[0038] It should be noted that these drawings are intended to
illustrate the general characteristics of structure and/or methods
utilized in certain example embodiments and to supplement the
written description provided below. These drawings are not,
however, to scale and may not precisely reflect the precise
structural or performance characteristics of any given embodiment,
and should not be interpreted as defining or limiting the range of
values or properties encompassed by example embodiments. For
example, the relative thicknesses and positioning of molecules,
layers, regions and/or structural elements may be reduced or
exaggerated for clarity. The use of similar or identical reference
numbers in the various drawings is intended to indicate the
presence of a similar or identical element or feature.
DETAILED DESCRIPTION OF THE EMBODIMENTS
[0039] Example embodiments will now be described more fully with
reference to the accompanying drawings. Example embodiments may,
however, be embodied in many different forms and should not be
construed as being limited to the embodiments set forth herein;
rather, these embodiments are provided so that this disclosure will
be thorough and complete, and will fully convey the concept of
example embodiments to those of ordinary skill in the art. In the
drawings, the thicknesses of layers and regions are exaggerated for
clarity. Like reference numerals in the drawings denote like
elements, and thus their description will be omitted.
[0040] It will be understood that when an element is referred to as
being "connected" or "coupled" to another element, it can be
directly connected or coupled to the other element or intervening
elements may be present. In contrast, when an element is referred
to as being "directly connected" or "directly coupled" to another
element, there are no intervening elements present. Like numbers
indicate like elements throughout. As used herein the term "and/or"
includes any and all combinations of one or more of the associated
listed items. Other words used to describe the relationship between
elements or layers should be interpreted in a like fashion (e.g.,
"between" versus "directly between," "adjacent" versus "directly
adjacent," "on" versus "directly on").
[0041] It will be understood that, although the terms "first",
"second", etc. may be used herein to describe various elements,
components, regions, layers and/or sections, these elements,
components, regions, layers and/or sections should not be limited
by these terms. These terms are only used to distinguish one
element, component, region, layer or section from another element,
component, region, layer or section. Thus, a first element,
component, region, layer or section discussed below could be termed
a second element, component, region, layer or section without
departing from the teachings of example embodiments.
[0042] Spatially relative terms, such as "beneath," "below,"
"lower," "above," "upper" and the like, may be used herein for ease
of description to describe one element or feature's relationship to
another element(s) or feature(s) as illustrated in the figures. It
will be understood that the spatially relative terms are intended
to encompass different orientations of the device in use or
operation in addition to the orientation depicted in the figures.
For example, if the device in the figures is turned over, elements
described as "below" or "beneath" other elements or features would
then be oriented "above" the other elements or features. Thus, the
exemplary term "below" can encompass both an orientation of above
and below. The device may be otherwise oriented (rotated 90 degrees
or at other orientations) and the spatially relative descriptors
used herein interpreted accordingly.
[0043] The terminology used herein is for the purpose of describing
particular embodiments only and is not intended to be limiting of
example embodiments. As used herein, the singular forms "a," "an"
and "the" are intended to include the plural forms as well, unless
the context clearly indicates otherwise. It will be further
understood that the terms "comprises", "comprising", "includes"
and/or "including," if used herein, specify the presence of stated
features, integers, steps, operations, elements and/or components,
but do not preclude the presence or addition of one or more other
features, integers, steps, operations, elements, components and/or
groups thereof.
[0044] Example embodiments are described herein with reference to
cross-sectional illustrations that are schematic illustrations of
idealized embodiments (and intermediate structures) of example
embodiments. As such, variations from the shapes of the
illustrations as a result, for example, of manufacturing techniques
and/or tolerances, are to be expected. Thus, example embodiments
should not be construed as limited to the particular shapes of
regions illustrated herein but are to include deviations in shapes
that result, for example, from manufacturing. For example, an
implanted region illustrated as a rectangle may have rounded or
curved features and/or a gradient of implant concentration at its
edges rather than a binary change from implanted to non-implanted
region. Likewise, a buried region formed by implantation may result
in some implantation in the region between the buried region and
the surface through which the implantation takes place. Thus, the
regions illustrated in the figures are schematic in nature and
their shapes are not intended to illustrate the actual shape of a
region of a device and are not intended to limit the scope of
example embodiments.
[0045] Unless otherwise defined, all terms (including technical and
scientific terms) used herein have the same meaning as commonly
understood by one of ordinary skill in the art to which example
embodiments belong. It will be further understood that terms, such
as those defined in commonly-used dictionaries, should be
interpreted as having a meaning that is consistent with their
meaning in the context of the relevant art and will not be
interpreted in an idealized or overly formal sense unless expressly
so defined herein.
[0046] FIG. 1 is a schematic view illustrating an apparatus of
packing a semiconductor package according to an example embodiment
of the inventive concepts, and FIG. 2 is a schematic view
illustrating a method of receiving a semiconductor package in a
pocket of a carrier tape of FIG. 1.
[0047] Referring to FIGS. 1 and 2, an apparatus 1 of packing a
semiconductor package according to the example embodiments may
include a carrier tape supply unit 10, a semiconductor package
packing unit 20, and a carrier tape winding unit 30.
[0048] The carrier tape supply unit 10 supplies a carrier tape T1
to the semiconductor package packing unit 20. The semiconductor
package packing unit 20 packs a semiconductor package in the
carrier tape T1. The carrier tape winding unit 30 winds the carrier
tape T1 in which the semiconductor package is packed.
[0049] The carrier tape supply unit 10 includes a carrier tape
supply reel 12 and a reel driving part (not shown). The carrier
tape T1 is wound round the carrier tape supply reel 12. The carrier
tape T1 may be formed of a resin material containing a conductive
material. The reel driving part (not shown) rotates the carrier
tape supply reel 12. When the carrier tape supply reel 12 is
rotated clockwise by the reel driving part, the carrier tape T1 may
be unwound from the carrier tape supply reel 12.
[0050] The carrier tape T1 may have a plurality of pockets P
receiving a plurality of the semiconductor packages PKG. The
plurality of pockets P may be formed along a longitudinal direction
of the carrier tape T1 by equal intervals. Transfer holes H, which
are used for transferring the carrier tape T1, may be formed at
both edge regions of the pockets P to be arranged in lines.
Protrusions 231 of a sprocket 230 described later are inserted in
the transfer holes H. The sprocket 230 and the protrusions 231 are
illustrated in FIG. 4. Due to a rotation of the sprocket 230, the
protrusions 231 are inserted in the transfer holes H and then the
protrusion 231 push sidewalls of the transfer holes H to get out
from the transfer holes H. According to these operations, the
carrier tape T1 is moved straight toward the semiconductor package
packing unit 20. The movement of the carrier tape T1 may also be
guided by a transfer rail 21.
[0051] The semiconductor package packing unit 20 includes a picker
22, a cover tape supply reel 24, an upper heating roller 26a, and a
lower heating roller 26b. The picker 22 picks up the semiconductor
package PKG and then puts the semiconductor package PKG in the
pocket P of the carrier tape T1. The picker 22 may pick up the
semiconductor package PKG by a vacuum suction method. The cover
tape supply reel 24 may disposed over the carrier tape T1. A cover
tape T2 is wound round the cover tape supply reel 24. The cover
tape T2 may be formed of a resin material containing a conductive
material. When the cover tape supply reel 24 is rotated
counterclockwise by a reel driving part (not shown), the cover tape
T2 may be unwound from the cover tape supply reel 24.
[0052] The upper heating roller 26a is disposed on the carrier tape
T1 and the lower heating roller 26b is disposed under the carrier
tape T1 to face the upper heating roller 26a. The carrier tape T1
and the cover tape T2 are disposed between the upper heating roller
26a and the lower heating roller 26b. The upper and lower heating
rollers 26a and 26b bond the cover tape T2 on the carrier tape T1
in thermo-compression. A groove (not shown) may be formed in the
lower heating roller 26b so that the pocket P of the carrier tape
T1 may not be in contact with the lower heating roller 26b. Heat
blocks may be replaced with the upper and lower heating roller 26a
and 26b. The heat blocks may move in up and down directions to bond
the cover tape T2 to the carrier tape T1 using
thermocompression.
[0053] The carrier tape winding unit 30 includes a carrier tape
adhesion member 100, a carrier tape transfer member 200, a carrier
tape cut member 300, and a reel replacement member 400.
[0054] FIG. 3 is an enlarged view of the carrier tape winding unit
of FIG. 1, and FIG. 4 is a cross-sectional view taken along a line
A-A' of FIG. 3. Referring to FIGS. 3 and 4, the carrier tape
adhesion member 100 include feeder 110, a chuck 120, a tape
adhesion tool 130, an adhesive tape cutter 140, and an adhesive
tape pressurization tool 150.
[0055] The feeder 110 may be disposed over and on the right of a
winding reel 420. A adhesive tape T3 is wound round the feeder 110.
When the feeder 110 is rotated counterclockwise by a driving part
(not shown), the adhesive tape T3 may be unwound from the feeder
110.
[0056] The chuck 120 may be disposed over and on the left of the
winding reel 420a to face the feeder 110. The chuck 120 may move
straight toward the feeder 110 to chuck the front of the fixing
tape T3 unwound from the feeder 110. For example, the chuck 120 may
move straight in a direction far away from the feeder 110 to extend
the chucked fixing tape T3 in length.
[0057] The tape adhesion tool 130 includes a first adhesion tool
132 and a second adhesion tool 134. The first adhesion unit 132 and
the second adhesion unit 134 are disposed between the feeder 110
and the chuck 120 and are spaced apart from each other by a desired
(or, alternatively a predetermined) interval in a horizontal
direction. The first adhesion unit 132 picks up one end of a
portion having a desired (or, alternatively a predetermined) length
of the fixing tape T3 and the second adhesion unit 134 picks up
another end of the portion having the desired (or, alternatively a
predetermined) length of the fixing tape T3. The first and second
adhesion units 132 and 134 may pick up the fixing taper T3 by a
vacuum suction method. The portion having the desired (or,
alternatively a predetermined) length of the fixing tape T3 may be
cut from the fixing tape T3 by the adhesive tape cutter 140 in the
state that the first and second adhesion units 132 and 134 pick up
the portion having the desired (or, alternatively a predetermined)
length of the adhesive tape T3.
[0058] The first and second adhesion units 132 and 134 may move in
up and down directions. In the state that the first and second
adhesion units 132 and 134 pick up the cut adhesive tape T3 (i.e.,
the cut portion having the desired (or, alternatively a
predetermined) length of the adhesive tape T3), the first and
second adhesion units 132 and 134 descend to bond the cut adhesive
tape T3 to the winding reel 420a. In more detail, the first and
second adhesion units 132 and 134 may bond the front end of the
carrier tape T1 to the winding reel 420a before a wind of the
winding reel 420a is started. The first and second adhesion units
132 and 134 may attach a cut back end of the carrier tape T1 to the
winding reel 420a or the outermost wound portion of the carrier
tape T1 after the winding of the winding reel 420a is completed.
This will be described in more detail later.
[0059] The tape pressurization tool 150 may be disposed between the
first adhesion unit 132 and the second adhesion unit 134. The tape
pressurization tool 150 may include a body 152 and a pressurization
part 154. The pressurization part 154 is a combination of a bottom
surface of the body 152 and a pressurization curved surface 155
having an upward concave shape 155 formed on a bottom surface of
the pressurization part 154. The tape pressurization tool 150 may
move in up and down directions. The tape pressurization tool 150
descends toward the winding reel 420a so that the pressurization
curved surface 155 pressurizes the adhesive tape T3. An adhesion
force of the adhesive tape T3 may be improved by the pressurization
force of the tape pressurization tool 150.
[0060] The carrier tape transfer member 200 transfers the carrier
tape T1 to the winding reel 420a. The carrier tape transfer member
200 includes a transfer rail 220, the sprocket 230, and a guide
240.
[0061] As illustrated in FIG. 4, the transfer rail 220 includes a
rail part 222 and grippers 224. The rail part 222 extends in a
first direction which is the transfer direction of the carrier tape
T1 toward the winding reel 420a. The rail part 222 guides the
carrier tape T1 to be transferred toward the winding reel 420a. A
pair of guide sills 223 are formed on a top surface of the rail
part 222. Both edge portions of the carrier tape T1 are safely
mounted on the pair of guide sills 223, respectively. The guide
grippers 224 are disposed over the guide sills 223 to prevent the
carrier tape T1 from breaking away from the transfer rail 220.
[0062] The sprocket 230 is disposed over the rail part 222 to
transfer the carrier tape T1. The sprocket 230 may penetrate the
guide gripper 224 and be disposed over the guide sill 223. A
plurality of protrusions 231 are formed on a circumferential
surface of the sprocket 230. The plurality of protrusions 231 are
inserted in the transfer holes H of the carrier tape T1 by the
rotation of the sprocket 230 and then the protrusions 231 push
sidewalls of the transfer holes H to get out from the transfer
holes H. According to these operations, the carrier tape T1 moves
straight toward the winding reel 420a. The sprocket 230 may be
intermittently rotated by a driving part 232 for a step movement of
the carrier tape T1. For example, the driving part 232 may be a
step motor.
[0063] The guide 240 is disposed under the transfer rail 220. The
guide 240 may go ahead and back in a longitudinal direction of the
transfer rail 220. The guide 240 goes ahead to a space between an
end portion of the transfer rail 220 and the winding reel 420a and
supports the carrier tape T1 passing through the end portion of the
transfer rail 220.
[0064] The carrier tape cut member 300 cuts the carrier tape T1
after the wind of the carrier tape T1 on the winding reel 420a is
completed. The carrier tape cut member 300 includes a carrier tape
holder 320 and a carrier tape cutter 340. The carrier tape holder
320 pressurizes and holds the carrier tape T1 to prevent the
carrier tape T1 wound on the winding reel 420a from being unwound.
For example, the carrier tape holder 320 may pressurize the carrier
tape T1 wound in a first quadrant with respect to a center of the
winding reel 420a. The carrier tape cutter 340 may be disposed
between the transfer rail 220 and the winding reel 420a. The
carrier tape cutter 340 cuts the carrier tape T1 held by the
carrier tape holder 320. For example, the carrier tape cutter 340
may cut the carrier tape T1 at any location between the end portion
of the transfer rail 220 and the top of a circumferential surface
of the winding reel 420a.
[0065] FIG. 5 is a plan view illustrating the reel replacement
member of FIG. 3 and FIG. 6 is a schematic view illustrating an
operation replacing a winding reel by a reel replacement
member.
[0066] Referring to FIGS. 3, 5, and 6, the reel replacement member
400 replaces the winding reel 420a where winding of the carrier
tape T1 is completed with a new winding reel 420b. Additionally,
after winding of the winding reel 420b is completed, the reel
replacement member 400 may replace the winding reel 420b with
another new winding reel 420c again. The reel replacement member
400 includes a rotation axis 410, an axis support member 430, an
axis driving part 440, and a base driving part 450.
[0067] The rotation axis 410 is separated from the end portion of
the transfer rail 220 in the transfer direction (hereinafter,
referred to as `a first direction`) of the carrier tape T1. An axis
of the rotation axis 410 is aligned in a second direction
perpendicular to the first direction in a plan view, as illustrated
in FIG. 5. The rotation axis 410 may be provided with a plurality
of the winding reels 420a, 420b, and 420c. The plurality of the
winding reels 420a, 420b, and 420c are rotated clockwise to be
wound with the carrier tape in which the semiconductor packages are
packed. Movement of outer winding reels 420a and 420c of the
winding reels 420a, 420b, and 420c along the rotation axis 410 is
limited by stoppers 412a and 412b. Hereinafter, the winding reels
420a, 420b, and 420c are referred to as a first winding reel, a
second winding reel, and a third winding reel, respectively.
[0068] The axis support member 430 supports the rotation axis 410.
The axis support member 430 may include support rods 432 and a base
434. The support rods 432 may support both ends of the rotation
axis 410 to rotate and may be vertically combined with a top
surface of the base 434. The axis driving part 440 may rotate the
rotation axis 410 and the base driving part 450 may move the base
434 straight in the second direction. The base driving part 450 may
be a linear motor. Additionally, the base driving part 450 may
include a combined structure of a motor and a motive power
transmission member converting a turning force of the motor into a
linear driving force.
[0069] After winding of the first winding reel 420a is completed,
the carrier tape cut member 300 cuts the carrier tape T1, and the
carrier tape adhesion member 100 attaches the adhesive tape T2 on
the cut carrier tape T1. Thereafter, the base driving part 450
moves the base 434 straight in the second direction to align the
second winding reel 420b with the carrier tape T1 on the transfer
rail 220. After the second winding reel 420b is aligned with the
carrier tape T1, the carrier tape T1 is moved toward the second
winding reel 420b, and then the carrier tape adhesion member 100
attaches the carrier tape T1 on the second winding reel 420b. As
described above, the reel replacement member 400 replaces the first
winding reel 420a where the winding of the carrier tape T1 is
completed with the second winding reel 420b. After the winding of
the second winding reel 420b is completed, the second winding reel
420b may be replaced with the third winding reel 420c by the same
method described above.
[0070] FIG. 7 is a flowchart illustrating a detailed method of
replacing a winding reel according to an example embodiment of the
inventive concepts.
[0071] After the winding of the first winding reel 420a is
completed (S10), the apparatus 1 of packing the semiconductor
packages illustrated in FIG. 1 operates an apparatus alarm (S20)
and then the apparatus 1 interrupts a process of packing the
semiconductor packages (S30). Subsequently, the carrier tape
adhesion member 100 prepares the adhesive tape which will be stuck
on the first winding reel 420a (S40).
[0072] The step S40 will be described in more detail with reference
to FIGS. 8A to 8D. The feeder 110 provides the adhesive tape T3.
The chuck 120 chucks the end of the adhesive tape T3 to extend the
adhesive tape T3 by a desired (or, alternatively a predetermined)
length. (FIG. 8A) The first adhesion unit 132 picks up a left end
of the desired (or, alternatively a predetermined) length of the
adhesive tape T3 and the second adhesion unit 134 picks up a right
end of the desired (or, alternatively a predetermined) length of
the adhesive tape T3. (FIG. 8B) The adhesive tape cutter 140 cuts
the adhesive tape T3 by the desired (or, alternatively a
predetermined) length. (FIG. 8C) The chuck 120 releases the
adhesive tape T3 and the adhesive tape cutter 140 returns to an
initial position. The cut fixing tape T3 maintains a picked up
state by the first and second adhesion tools 132 and 134. (FIG.
8D)
[0073] Referring to FIG. 7 again, an end of the wound carrier tape
T1 is fixed on the first winding reel 420a by using the prepared
adhesive tape T3 (S50).
[0074] The step S50 will be described in more detail with reference
to FIGS. 9A to 9E. The carrier tape holder 320 pressurizes and
holds the carrier tape T1 wound on the first winding reel 420a
(FIG. 9A) and the carrier tape cutter 340 cuts the carrier tape T1.
(FIG. 9B) The first winding reel 420a rotates clockwise such that
the cut end portion of the carrier tape T1 is located over the
center of the first winding reel 420a. At this time, the carrier
tape cutter 340 returns to an initial position. (FIG. 9C) The first
and second adhesion units 132 and 134 descends with picking up the
adhesive tape T3 so that the first and second adhesion units 132
and 134 stick the adhesive tape T3 to the cut end portion of the
carrier tape T1. At this time, the cut end portion of the carrier
tape T1 is located on a center region of the adhesive tape T3. In
other words, the first and second adhesion units 132 and 134 may
stick the adhesive tape T3 to the cut end portion of the carrier
tape T1 and the outermost wound portion of the carrier tape T1. At
this time, the carrier tape holder 320 returns to an initial
position. (FIG. 9D) The tape pressurization tool 150 pressurizes
the adhesive tape T3 so that the adhesive tape T3 is stuck closely
to the carrier tape T1. (FIG. 9E)
[0075] Referring to FIG. 7 again, the first winding reel 420a is
replaced with the second winding reel 420b (S60) and the carrier
tape adhesion member 100 prepares a adhesive tape which will be
stuck on the second winding reel 420b (S70). The step S70 may be
substantially the same as the step S40. Thus, the detail
description for the step S70 is omitted. A front end of the carrier
tape T1, which will be wound, is attached to the second winding
reel 420b by using the prepared adhesive tape T3 (S80).
[0076] The step S80 will be described in more detail with reference
to FIGS. 10 A to 10E. The guide 240 proceeds toward the second
winding reel 420b and supports the carrier tape T1 passing through
the end portion of the transfer rail 220. (FIG. 10A) The first and
second adhesion units 132 and 134 descend with picking up the
adhesive tape T3 so that the first and second adhesion units 132
and 134 attach the adhesive tape T3 to the carrier tape T1. At this
time, the front end of the carrier tape T1 is located on a center
region of the fixing tape T3. In other words, the first and second
adhesion units 132 and 134 attach the adhesive tape T3 to the
carrier tape T1 so that a region of the carrier tape T1 is
overlapped with a region of the adhesive tape T3. (FIG. 10B) The
guide 240 returns to an initial position. (FIG. 10C) The first and
second adhesion units 132 and 134 descends toward the second
winding reel 420b so that the first and second adhesion units 132
and 134 attach the rest region of the adhesive tape T3 that does
not overlap with the carrier tape T1 to a center portion of the
second winding reel 420b (i.e., hub (not shown)). (FIG. 10D) The
tape pressurization tool 150 descends toward the second winding
reel 420b so that the tape pressurization tool 150 pressurizes the
adhesive tape T3 to attach the adhesive tape T3 closely to the
center portion of the second winding reel 420b (i.e., hub (not
shown)). (FIG. 10E)
[0077] Referring to FIG. 7 again, the apparatus 1 of packing the
semiconductor packages restarts the process packing the
semiconductor packages (S90).
[0078] As described above, the apparatus 1 of packing the
semiconductor packages according to example embodiments of the
inventive concepts can replace the winding reels automatically.
Thus, the packing process using the apparatus of packing the
semiconductor packages according to the example embodiment of the
inventive concepts may improve work efficiency and productivity as
compared with a conventional manual packing semiconductor
packages.
[0079] While example embodiments have been particularly shown and
described, it will be understood by one of ordinary skill in the
art that variations in form and detail may be made therein without
departing from the spirit and scope of the claims. Therefore, it
should be understood that the above embodiments are not limiting,
but illustrative. Thus, the scope of the inventive concept is to be
determined by the broadest permissible interpretation of the
following claims and their equivalents, and shall not be restricted
or limited by the foregoing description.
