are shown for clarity of illustration. In FIGS. 2A, 2B, and 4A to
4C, the substrate 10 is not shown for clarity of illustration.
[0012] Referring to FIGS. 1 and 2A, a semiconductor device package
according to some embodiments may include a first semiconductor
package 100 and a second semiconductor package 200, and the
interposer 300 is on the substrate 10. The first semiconductor
package 100 may be on the substrate 10. The first semiconductor
package 100 may include a first semiconductor package substrate
101, a first semiconductor chip 110, and a first molding material
120.
[0013] The first semiconductor package substrate 101 may be a
substrate for a package, for example, a printed circuit board (PCB)
or a ceramic substrate. The first semiconductor package substrate
101 may include first and second surfaces facing each other. The
first semiconductor chip 110 may be mounted on the first surface of
the first semiconductor package substrate 101. A first connection
element (e.g., connector) 103 may be attached to the second surface
of the first semiconductor package substrate 101. A predetermined
number of the first connection elements (or connectors) 103 are
illustrated. A different number of the first connection elements
103 may be attached to the second surface of the first
semiconductor package substrate 101 in another embodiment.
[0014] The first connection element 103 may be, for example, a
conductive ball or a solder ball. For example, the first connection
element 103 may be one of a conductive bump, a conductive spacer,
and a pin grid array (PGA). The first semiconductor package 100 may
be electrically connected to an external device through the first
connection element 103.
[0015] The first semiconductor chip 110 may be, for example, a flip
chip. The lower surface of the first semiconductor chip 110 may be
a first semiconductor device circuit region 111. A second
connection element 113 may be in the first semiconductor device
circuit region 111. The second connection element 113 may be, for
example, a solder ball or a conductive bump.
[0016] The first semiconductor chip 110 may be electrically
connected to the first semiconductor package substrate 101 through
the second connection element 113. A predetermined number of the
second connection elements 113 are illustrated. A different number
of the second connection elements 113 may be included in other
embodiments.
[0017] Referring to FIGS. 1, 2A, and 3, the shape of the first
semiconductor chip 110 may be, for example, a stepped shape. In
some embodiments, the width W1 of a first portion 110_1 may be
larger than a width W2 of a second portion 110_2. The first
semiconductor chip 110 may include the first portion 110_1 and the
second portion 110_2. The second portion 110_2 may protrude from
the first portion 110_1. In some embodiments, the first portion
110_1 may include, for example, the first semiconductor device
circuit region 111. In some embodiments, The first portion 110_1
and the second portion 110_2 may be connected to each other.
[0018] Each of the first portion 110_1 and the second portion 110_2
may be a portion of one first semiconductor chip 110. In one
embodiment, the first portion 110_1 and the second portion 110_2
may be different semiconductor chips. In one embodiment, the first
semiconductor chip 110 may include two different semiconductor
chips.
[0019] The shape of the first semiconductor chip 110 may be
different from that illustrated in FIG. 2A. For example, referring
to FIG. 2B, the shape of a first semiconductor chip 110' may not
have any steps. A first' portion 110'_1 of the first semiconductor
chip 110' may be a portion not inserted into a first interposer
hole 300h_1. A second portion 110'_2 of the first' semiconductor
chip 110' may be inserted into the first interposer hole 300h_1.
The first semiconductor chip 110' may be one semiconductor chip, or
in another embodiment a stack of a plurality of semiconductor chips
may be included.
[0020] Referring again to FIGS. 1 and 2A, the first molding
material 120 may include a hole 310h for receiving a third
connection element 310. The first molding material 120 may
completely fill a space between the first semiconductor chip 110
and the first semiconductor package substrate 101. The first
molding material 120 may completely surround the side surface of
the first portion 110_1 and the side surface of the third
connection element 310. The first molding material 120 may
completely fill, for example, a space between the upper surface of
the first portion 110_1 of the first semiconductor chip and the
interposer 300.
[0021] The first molding material 120 may surround only a part of
the side surface of the second portion 110_2, for example. In one
embodiment, the first molding material 120 may completely fill the
space between the upper surface of the first portion 110_1 and the
interposer 300, but may not contact the side surface of the second
portion 110_2. Accordingly, an empty space may be between the side
surface of the second portion 110_2 and the first molding material
120. The first molding material 120 may be, for example, an epoxy
molding compound (EMC).
[0022] The second semiconductor package 200 may be on the substrate
10 and may include a second semiconductor package substrate 201, a
second semiconductor chip 210, and a second molding material
220.
[0023] The second semiconductor package substrate 201 may be the
same as or different from the first semiconductor package substrate
101. The second semiconductor package substrate 201 may include
first and second surfaces facing each other. The second
semiconductor chip 210 may be mounted on the first surface of the
second semiconductor package substrate 201. A fourth connection
element 203 may be attached to the second surface of the second
semiconductor package substrate 201. The fourth connection element
203 may be the same as or different from the first connection
element 103. The second semiconductor package 200 may be
electrically connected to an external device or another
semiconductor package through the fourth connection element
203.
[0024] The second semiconductor chip 210 may be attached to the
second semiconductor package substrate 201 through a first adhesive
215. The second semiconductor chip 210 may be electrically
connected to the second semiconductor package substrate 201 through
a fifth connection element 213, for example. The upper surface of
the second semiconductor chip 210 may be a second semiconductor
device circuit region 211. The fifth connection element 213 may be,
for example, wire bonding. The second semiconductor chip 210 is one
semiconductor chip, or in another embodiment a stack of a plurality
of semiconductor chips may be included.
[0025] Each of the first semiconductor chip 110 and the second
semiconductor chip 210 may be, for example, a memory chip, a logic
chip, or another type of church. When the first semiconductor chip
110 and/or the second semiconductor chip 210 is a logic chip, the
first semiconductor chip 110 and/or the second semiconductor chip
210 may be variously designed in consideration of operations to be
performed. When the first semiconductor chip 110 and/or the second
semiconductor 202 is a memory chip, the memory chip may be, for
example, a non-volatile memory chip.
[0026] The second molding material 220 may be on the second
semiconductor package substrate 201. The second molding material
220 may seal the upper surface of the second semiconductor package
substrate 201, the second semiconductor chip 210, and the fifth
connection element 213. The second molding material 220 may
include, for example, the same material as the first molding
material 120.
[0027] The interposer 300 may be between the first semiconductor
package 100 and the second semiconductor package 200. The
interposer 300 may electrically connect the first semiconductor
package 100 to the second semiconductor package 200. The interposer
300 may include first and second surfaces facing each other. A
connection element of the semiconductor package on the interposer
300 may be on the first surface of the interposer 300. The third
connection element 310 may be attached to the second surface of the
interposer 300. The interposer 300 may include the first interposer
hole 300h_1 passing through the interposer 300. The first
interposer hole 300h_1 may extend from the first surface to the
second surface of the interposer 300.
[0028] In some embodiments, the second semiconductor package 200
may be on the first semiconductor package 100. For example, the
first semiconductor package 100 and the second semiconductor
package 200 may have a Package on Package (PoP) structure. The
first portion 110_1 of the first semiconductor chip 110 may be
between the second portion 110_2 and the first semiconductor
package substrate 101. The interposer 300 may be between the first
semiconductor package 100 and the second semiconductor package 200.
The third connection element 310 may be inserted into a hole 310h
of the first molding material 120. The fourth connection element
203 may be on the first surface of the interposer 300. For example,
the fourth connection element 203 may be between the first surface
of the interposer 300 and the second semiconductor package
substrate 201. The fourth connection element 203 may be on a
portion of the first surface of the interposer 300, other than a
portion where the first interposer hole 300h_l is formed.
[0029] The first semiconductor package substrate 101 may be
electrically connected to the interposer 300 through the third
connection element 310. The interposer 300 may be electrically
connected to the second semiconductor package substrate 201 through
the fourth connection element 203.
[0030] The second portion 110_2 of the first semiconductor chip may
be inserted into the first interposer hole 300h_1. For example, the
first interposer hole 300h_1 may expose the second portion 110_2 of
the first semiconductor chip when viewed in a direction from the
first surface of the interposer 300 toward the second surface of
the interposer 300 as in FIG. 1.
[0031] The second portion 110_2 of the first semiconductor chip may
protrude from the upper surface of the first surface of the
interposer 300. In one embodiment, depending on a semiconductor
chip fabricating process, the second portion 110_2 may not protrude
from the upper surface of the first surface of the interposer
300.
[0032] Referring to FIGS. 1, 2A, and 2C, a portion 110_1a of the
first portion of the first semiconductor chip may at least
partially overlap a fourth_first connection element 203_1. The
overlapping direction may be, for example, a vertical direction
with respect to the first semiconductor package substrate 101. For
example, the fourth connection element 203 may include a plurality
of connection elements for electrically connecting the interposer
300 with the second semiconductor package 200. For example, a
plurality of connection elements of the fourth connection element
203 may include the fourth_first connection element 203_1. The
fourth_first connection element 203_1 may be a connection element
closest to the first interposer hole 300h_1 among the plurality of
connection elements in the fourth connection element 203. The
portion 110_1a of the first portion of the first semiconductor chip
may be a portion including an end portion 110_1e of the first
portion of the first semiconductor chip. For example, the portion
110_1a of the first portion of the first semiconductor chip may not
overlap the second portion 110_2 of the first semiconductor
chip.
[0033] Referring again to FIGS. 1 and 2A, an empty space may be
between a sidewall of the first interposer hole 300h_1 and a
sidewall of the second portion 110_2 of the first semiconductor
chip. For example, the area of the first interposer hole 300h_1 may
be larger than the area of the upper surface of the second portion
110_2 of the first semiconductor chip. Also, for example, an empty
space may be between the upper surface of the second portion 110_2
of the first semiconductor chip and the second surface of the
second semiconductor package substrate 201.
[0034] As shown in FIG. 4A, a fourth connection element 203' and a
pad 203p may be between the upper surface of the first
semiconductor chip 110 and the second surface of the second
semiconductor package substrate 201. The fourth connection element
203' may include a material (e.g., a heat transfer material) for
transferring the heat of the first semiconductor package 100 to the
outside. The pad 203p may be, for example, a wetting layer
including an easily wettable material. The pad 203p may be, for
example, a metal wetting layer. The first semiconductor chip 110
may be thermally connected to the second semiconductor package 200
through the fourth' connection element 203' and the pad 203p on the
upper surface of the first semiconductor chip 110.
[0035] A heat transfer material may be, for example, between the
sidewall of the first interposer hole 300h_1 and the sidewall of
the second portion 110_2 of the first semiconductor chip. Further,
for example, as shown in FIG. 4B, a heat transfer material layer
400 may be further formed between the upper surface of the second
portion 110_2 of the first semiconductor chip and the second
surface of the second semiconductor package substrate 201. The heat
transfer material layer 400 may be, for example, a thermal
interface material (TIM). In FIG. 4B, the heat transfer material
layer 400 is formed only between the upper surface of the second
portion 110_2 of the first semiconductor chip and the second
surface of the second semiconductor package substrate 201.
[0036] In one embodiment, the heat transfer material layer 400 may
be partially formed along the sidewall of the second portion 110_2
of the first semiconductor chip, as well as between the upper
surface of the second portion 110_2 of the first semiconductor chip
and the second surface of the second semiconductor package
substrate 201. The heat transfer material layer 400 may fill at
least a part of the empty space between the sidewall of the second
portion 110_2 of the first semiconductor chip and the sidewall of
the first interposer hole 300h_l. The first semiconductor chip 110
may be thermally connected to the second semiconductor package 200
through the heat transfer material layer 400.
[0037] As shown in FIG. 4C, an insertion adhesive layer 401 may be
between the heat transfer material layer 400 and the second surface
of the second semiconductor package substrate 201.
[0038] In the semiconductor device package according to some
embodiments, a portion of the first semiconductor chip 110 may be
inserted into the first interposer hole 300h_1 to increase the
overall thickness of the first semiconductor chip 110. When the
overall thickness of the first semiconductor chip 110 is increased,
the heat generated from the first semiconductor chip 110 may be
effectively transferred in a horizontal direction. When the heat is
effectively transferred in the horizontal direction, the thermal
resistance is reduced and performance of the semiconductor device
package may be improved. Further, when the heat is effectively
transferred in the horizontal direction, the temperature
distribution inside the semiconductor chip becomes uniform. As a
result, reliability of the semiconductor device package may be
improved.
[0039] According to some embodiments, in the semiconductor device
package, the second portion 110_2 of the first semiconductor chip
may be inserted into the first interposer hole 300h_1. Accordingly,
the heat generated from the first semiconductor chip 110 may be
effectively transferred in the vertical direction. When the heat is
effectively transferred in the vertical direction, the thermal
resistance is reduced and performance of the semiconductor device
package may be improved.

surround the side surface of the second semiconductor chip 210 and
the side surface of the third connection element 310. The second
molding material 220 may be on the upper surface of the second
semiconductor chip 210 to cover the upper surface of the second
semiconductor chip 210. In one embodiment, the second molding
material 220 may cover only a part of the upper surface of the
second semiconductor chip 210.
[0047] The first connection element 103 may be on the first surface
of the interposer 300. The first connection element 103 may be
between the first surface of the interposer 300 and the first
semiconductor package substrate 101. The first connection element
103 may be on a portion of the first surface of the interposer 300
other than a portion where the first interposer hole 300h_1 is
formed.
[0048] The first semiconductor package substrate 101 may be
electrically connected to the interposer 300 through the first

the sidewall of the second portion 110_2 of the first semiconductor
chip and the sidewall of the first substrate hole 101h _1, and
between the sidewall of the second portion 110_2 of the first

and the area of the first substrate hole 101h_1 may be larger than
the area of the upper surface of the second portion 110_2 of the
first semiconductor chip.
[0053] In one embodiment, as shown in FIG. 7, the heat transfer

FIG. 9 illustrates a cross-sectional view taken along line A-A' of
FIG. 1 according to an embodiment.
[0055] Referring to FIGS. 1, 2A, and 8A, the second semiconductor
package 200 may be on the first semiconductor package 100. The
semiconductor device package of FIG. 2A and the semiconductor
device package of FIG. 8A may be substantially the same except for
a second substrate hole 201h and the second portion 110_2 of the
first semiconductor chip. The second semiconductor package
substrate 201 may include a first surface on which the second

the fourth connection element 203 is attached. The first and second
surfaces may face each other.
[0056] The second semiconductor package substrate 201 may include
the second substrate hole 201h passing through the second
semiconductor package substrate 201. The second substrate hole 201h
may extend from the first surface to the second surface of the
second semiconductor package substrate 201. The second portion
110_2 of the first semiconductor chip may be inserted into the
second substrate hole 201h through the first interposer hole
300h_1. For example, at least a part of the second portion 110_2 of
the first semiconductor chip may be inserted into the second
semiconductor package substrate 201.
[0057] In one embodiment, the second portion 110_2 of the first
semiconductor chip may include a portion to be inserted into the
first interposer hole 300h_1 and a portion to be inserted into the
second substrate hole 201h. The upper surface of the second portion
110_2 of the first semiconductor chip may be in the portion to be
inserted into the second substrate hole 201h. The upper surface of
the second portion 110_2 of the first semiconductor chip may be
below the first surface of the second semiconductor package
substrate 201. In some embodiments, the width W1 of the first
portion 110_1 of the first semiconductor chip may be substantially
the same as the width W2 of the second portion 110_2 of the first
semiconductor chip. In this case, the portion to be inserted into
the first interposer hole 300h_1 and the second substrate hole 201h
may be the second portion 110_2 of the first semiconductor chip.
The remaining portion may be the first portion 110_1 of the first
semiconductor chip.
[0058] An empty space may be between the upper surface of the
second portion 110_2 of the first semiconductor chip and the first
adhesive 215. Also, an empty space may be between the sidewall of
the second portion 110_2 of the first semiconductor chip and the
sidewall of the second substrate hole 201h, between the sidewall of
the second portion 110_2 of the first semiconductor chip and the
sidewall of the first interposer hole 300h_1, and between the
sidewall of the second portion 110_2 of the first semiconductor
chip and the fourth connection element 203. In one embodiment, the
pad and the fourth' connection element (e.g., see FIG. 4A) for
thermally connecting the first semiconductor package 100 to the
second semiconductor package 200 may be further disposed between
the upper surface of the second portion 110_2 of the first
semiconductor chip and the first adhesive 215.
[0059] Further, as shown in FIG. 9, the heat transfer material
layer 400 may be between the upper surface of the second portion
110_2 of the first semiconductor chip and the first adhesive 215.
The heat transfer material layer 400 may fill, for example, at
least a part of the empty space between the sidewall of the second
portion 110_2 of the first semiconductor chip and the sidewall of
the second substrate hole 201h. The heat transfer material layer
400 may further include an optional insertion adhesive layer.
[0060] Referring again to FIGS. 1, 2A, 8A, and 8B, the portion
110_1a of the first portion of the first semiconductor chip may at
least partially overlap the fourth first connection element 203_1.
The overlapping direction may be, for example, a vertical direction
with respect to the first semiconductor package substrate 101.
[0061] FIG. 10 illustrates a cross-sectional view taken along line
A-A' in FIG. 1 according to another embodiment. Referring to FIGS.
1, 8A, 8B, and 10, the second semiconductor package 200 may be on
the first semiconductor package 100. The semiconductor device
package of FIG. 8A and the semiconductor device package of FIG. 10
may be substantially the same, except for a cavity 201c. For
example, as compared with the second semiconductor package
substrate 201 of FIG. 8A, the second semiconductor package
substrate 201 of FIG. 10 may include the cavity 201c instead of the
second substrate hole 201h. The cavity 201c may not pass through
the second semiconductor package substrate 201. The cavity 201c may
be formed by removing a part of the second surface of the second
semiconductor package substrate 201.
[0062] The second portion 110_2 of the first semiconductor chip may
be inserted into the cavity 201c through the first interposer hole
300h_1. The second portion 110_2 of the first semiconductor chip
may include a portion to be inserted into the first interposer hole
300h_1 and a portion to be inserted into the cavity 201c. The upper
surface of the second portion 110_2 of the first semiconductor chip
may be in the portion to be inserted into the cavity 201c. In some
embodiments, the width W1 of the first portion 110_1 of the first
semiconductor chip may be substantially the same as the width W2 of
the second portion 110_2 of the first semiconductor chip. In this
case, the portion to be inserted into the first interposer hole
300h_1 and the cavity 201c may be the second portion 110_2 of the
first semiconductor chip. The remaining portion of the first
semiconductor chip may be the first portion 110_1 of the first
semiconductor chip.
[0063] An empty space may be between the upper surface of the
second portion 110_2 of the first semiconductor chip and the cavity
201c. In one embodiment, one of the heat transfer material layer
(e.g., see FIG. 4B) and the fourth connection element (e.g., see
FIG. 4A) may be in an empty space between the upper surface of the
second portion 110_2 of the first semiconductor chip and the cavity
201c. As a result, the first semiconductor package 100 may be
thermally connected to the second semiconductor package 200. When
the fourth connection element is in the empty space between the
upper surface of the second portion 110_2 of the first
semiconductor chip and the cavity 201c, a pad (e.g., a wetting
layer) may be between the fourth connection element and the upper
surface of the second portion 110_2 of the first semiconductor
chip.
[0064] In the semiconductor device package according to some
embodiments, heat dissipation generated from the first
semiconductor chip 110 and the like may be effective as described
above. In addition, by forming the second substrate hole 201h or
the cavity 201c in the second semiconductor package substrate 201
of the second semiconductor package 200 on the first semiconductor
package 100, the chances of warpage may be reduced.

embodiments, the width W1 of the first portion 110_1 of the first
semiconductor chip may be substantially the same as the width W2 of
the second portion 110_2 of the first semiconductor chip. In this
case, the portion to be inserted into the first interposer hole
300h_1 may be the second portion 110_2 of the first semiconductor
chip. The remaining portion of the first semiconductor chip may be
the first portion 110_1 of the first semiconductor chip.

may be substantially the same as the second semiconductor package
substrate 201 of FIG. 8A.
[0068] The second semiconductor chip 210 may have, for example, a
stepped shape. The second semiconductor chip 210 may include a
third portion 210_1 and a fourth portion 210_2. The fourth portion
210_2 of the second semiconductor chip may protrude from the third
portion 210_1 of the second semiconductor chip. The third portion
210_1 of the second semiconductor chip may include, for example,
the second semiconductor device circuit region 211. The third
portion 210_1 and the fourth portion 210_2 of the second
semiconductor chip may be connected to each other.
[0069] Each of the third portion 210_1 and the fourth portion 210_2
of the second semiconductor chip are illustrated to be a part of
one second semiconductor chip 210. In one embodiment, the third
portion 210_1 and the fourth portion 210_2 of the second
semiconductor chip may be different semiconductor chips,
respectively. In one embodiment, the second semiconductor chip 210
may be replaced, for example, by two different semiconductor chips.
The width W3 of the third portion 210_1 of the second semiconductor
chip may be different from (e.g., larger than) the width W4 of the
fourth portion 210_2 of the second semiconductor chip.
[0070] The second semiconductor chip 210 may be electrically
connected to the second semiconductor package substrate 201 through
the fifth connection element 213. The fifth connecting element 213
may be, for example, wire bonding. The second semiconductor chip
210 may be electrically connected to the second semiconductor
package substrate 201, for example, through the first adhesive 215.
The first adhesive 215 may be between the third portion 210_1 of
the second semiconductor chip and the second semiconductor package
substrate 201.
[0071] The fourth portion 210_2 of the second semiconductor chip
may be inserted into the second substrate hole 201h. The upper
surface of the fourth portion 210_2 of the second semiconductor
chip may face the upper surface of the second portion 110_2 of the
first semiconductor chip inserted in the first interposer hole
300h_1. The second portion 110_2 of the first semiconductor chip
may be disposed between the fourth portion 210_2 of the second
semiconductor chip and the first portion 110_1 of the first
semiconductor chip.
[0072] An empty space may be between the upper surface of the
fourth portion 210_2 of the second semiconductor chip and the upper
surface of the second portion 110_2 of the first semiconductor chip
inserted in the first interposer hole 300h_1. Further, an empty
space may be between the sidewall of the fourth portion 210_2 of
the second semiconductor chip and the sidewall of the second
substrate hole 201h.
[0073] As shown in FIG. 12, in one embodiment, the heat transfer
material layer 400 may be between the upper surface of the fourth
portion 210_2 of the second semiconductor chip and the upper
surface of the second portion 110_2 of the first semiconductor chip
inserted in the first interposer hole 300h_1. The heat transfer
material layer 400 is illustrated to be only between the upper
surface of the fourth portion 210_2 of the second semiconductor
chip and the upper surface of the second portion 110_2 of the first
semiconductor chip inserted in the first interposer hole 300h_1. In
one embodiment, the heat transfer material layer 400 may fill at
least a part of the empty space between the sidewall of the fourth

fill at least a part of the empty space between the sidewall of the
second portion 110_2 of the first semiconductor chip and the
sidewall of the first interposer hole 300h_1. In some embodiments,

substrate 101. The first region and the second region of the
interposer 300 may be regions spaced apart from each other. The
first region may be a region where more heat is generated due to a

interposer 300 may include the first interposer hole 300h_1. The
second region of the interposer 300 may not include a hole passing
through the second region of the interposer 300.
[0078] The first region of the interposer 300 may include a second

203_1 in FIG. 2C) of the connection elements of the semiconductor
package may overlap a portion (e.g., the portion 110_1a of the
first portion of the first semiconductor chip of FIG. 2C) of the

[0079] In some embodiments, the width W1 of the first portion 110_1
of the first semiconductor chip may be substantially the same as

[0105] Referring to FIG. 25B, a part of the first surface 1000_1 of
the wafer may be removed to form a plurality of recesses which are
spaced apart from each other. The plurality of recesses may include
a first recess r1 and a second recess r2. The first recess r1 and
the second recess r2 are illustrated to have a rectangular shape,

the first surface 1000_1 of the wafer. For example, in the case of
a silicon wafer, a portion irradiated with the laser beam may be
changed to polysilicon. A portion of the first surface 1000_1 of
the wafer on which the laser beam is locally irradiated may be
removed through an etching process to form a plurality of recesses.
