Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a container, especially to
a container for storing semiconductor devices.
[0003] 2. Description of Related Art
[0004] Semiconductor chips whose linear width is smaller than 90 nm
have been produced in wafer foundries or in semiconductor
fabrication plants due to breakthroughs and developments in wafer
fabrication techniques. More semiconductor devices per unit wafer
are produced along with the minimized linear width and the
increased integrated density. But the semiconductor devices with
high integrated density are quite sensitive. Even a bit of
contaminants such as particles, dust, organic materials, gas,
volatiles, etc result in defects in the semiconductor devices, or
static electricity and a short circuit that damage the
semiconductor devices.
[0005] In general manufacturing processes of semiconductor devices,
a clean room with a low level of air pollutants is used for
protection of the semiconductor devices. After being produced, a
protective container is required for pollution control of the
semiconductor devices during transportation of the semiconductor
devices.
[0006] To prevent damages to semiconductor devices occurred during
transportation or storage, many techniques that focus on the
improvement of container structure and fastening members in the
container have been provided. In an operating system of a
standardized mechanical interface, a machine pin is inserted into a
driver of a fastening member in the container so as to open and
close the container.
[0007] However, friction occurs between components of fastening
members in the container. Thus not only operation of the fastening
member is unstable but the container is not opened or closed
smoothly. Even some contaminants are produced due to the friction
and the semiconductor devices stored in the container get
polluted.
[0008] In order to solve the above problems, there is a need to
have a novel container for storing semiconductor devices that
includes at least one fastening member having at least one fastener
and at least one driver. A rolling element is mounted on the
fastener for reducing contact area between the fastener and the
driver and minimizing friction between the fastener and the driver.
Thus no contaminants produced in the container and the
semiconductor devices in the container will not be polluted. The
container is of high cleanness.
SUMMARY OF THE INVENTION
[0009] Therefore it is a primary object of the present invention to
provide a container for storing semiconductor devices that includes
a fastening member having at least one fastener and at least one
driver. The fastener is mounted with a rolling element in contact
with the driver. Thus contact area between the fastener and the
driver is reduced and friction between the fastener and the driver
is minimized to prevent production of contaminants and protect the
semiconductor devices in the container. The high cleanness of the
container is attained. Moreover, the rolling element is moved along
with rotation of the driver and friction between the fastener and
the driver is effectively reduced. Thus the fastening member works
well and the container is opened and closed smoothly.
[0010] In order to achieve the above objects, a container for
storing semiconductor devices of the present invention includes a
cover, a receiving body with at least one insertion hole on a side
wall, and a driver. The receiving body consists of at least one
fastener disposed therein. The fastener is composed of a fastening
body, at least one fixing part, a driving part and a rolling
element. The fixing part is arranged at one side of the fastening
body and corresponding to the insertion hole of the receiving body
while the driving part is disposed on the other side of the
fastening body. The rolling part is mounted on the driving part.
The driver is disposed in the receiving body, against the driving
part and in contact with the rolling element of the fastener. The
cover is covered over the receiving body that includes at least one
fastening part at the side wall thereof. The fastening part is
corresponding to the insertion hole. When the driver is rotated, it
drives the fastener to move in the receiving body. The fixing part
of the fastener is inserted through the insertion hole of the
receiving body to be mounted on the fastening part of the cover.
Thus the cover is fixed on the receiving body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0021] For solving the problem of friction occurred between each
component of the fastening member of the container that cause
contamination of semiconductor stored in the container, a container
for storing semiconductor devices of the present invention is
provided.
[0022] Refer to FIG. 1, FIG. 2 and FIG. 3, a container for storing
semiconductor devices 1 includes a cover 10, a receiving body, and
a seal plate 112. At least one semiconductor device is loaded on an
outer surface of the receiving body 111 and the cover 10 is
disposed over the outer surface of the receiving body 111. The
receiving body 111 is mounted with a fastening member therein and
the seal plate 112 is against the fastening member for fixing the
fastening member in the receiving body 111. The cover 10 is fixed
on the receiving body 111 by the fastening member. Thus the
container 1 is airtight and is free from external contaminants.
Therefore the semiconductor device (such as photomask, wafer or
others) will not be polluted. For further increasing air-tightness
of the container 1, a seal 14 is set between the cover 10 and the
receiving body 111 to prevent contaminants from entering the
container 1. Thus a high level of cleanness is achieved in the
container 1.
[0023] The receiving body 111 is composed of an inner surface 1111
and a side wall 1112 around a periphery of the inner surface 1111.
Thus a receiving space is formed in the receiving body 111. The
fastening member of this embodiment is mounted in the receiving
space and is having two fasteners 121 and a driver 122. The two
fasteners 121 are symmetrically arranged at the inner surface 1111
of the receiving body 111 and each fastener 121 consists of a
fastening body 1211 and two fixing parts 1212 disposed on one side
of the fastening body 1211. The side wall 1112 of the receiving
body 111 is set with four insertion holes 1110 respectively
corresponding to four fixing parts 1212 of the two fasteners 121.
As to the cover 10, its sidewall is also arranged with four
fastening parts 102 (as shown in FIG. 1) corresponding to the four
insertion holes 1110 of the receiving body 111 respectively. Thus
the four fixing parts 1212 of the two fasteners 121 are
respectively passed through the four insertion holes 1110 of the
receiving body 111 so as to fix the cover 10 on the receiving body
111. The fixing part 1212 is a convex part while the fastening part
102 corresponding to the fixing part 1212 is a slot in this
embodiment. The fixing part 1212 and the fastening part 102 can
also be in other forms that lock with each other.
[0024] Refer to FIG. 4, the driver 122 is disposed on the inner
surface of the receiving body 111 and is between the two fasteners
121. Moreover, the inner surface of the receiving body 111 is
arranged with a pivot part 1113 as shown in FIG. 3. The driver 122
consists of a driving body 1221 and a rotating shaft 1222 (as shown
in FIG. 2). The driving body 1221 includes a first surface 12211
and a second surface 12212 while the rotating shaft 1222 is
disposed on the first surface 12211 of the driving body 1221 and is
pivotally connected to the pivot part 1113 (as shown in FIG. 3).
Thus the driver 122 is rotatable in the receiving body 111.
Moreover, a bearing 1114 is further disposed on the pivot part 1113
of the receiving body 111 and the rotating shaft 1222 is pivotally
connected to the bearing 1114 for being pivotally connected to the
pivot part 1113. The bearing 114 is used to reduce friction between
the pivot part 1113 and the rotating shaft 1222 and allow the
driver 122 rotating smoothly in the receiving body 111.
[0025] Refer to FIG. 2 ad FIG. 5, the driver 122 further includes
two guiding members 1223, respectively is a projecting rod. The two
guiding members 1223 project from the first surface 12211 of the
driving body 1221 and respectively extend from the rotating shaft
1222 to a periphery of the driving body 1221. The other side of the
fastening body 1211 of each fastener 121 is arranged with a driving
part 1213. The driving parts 1213 of the two fasteners 121 are
respectively located between the two guiding members 1223 of the
driver while the two guiding members 1223 are against the
corresponding driving part 1213 respectively.
[0026] The seal plate is fixed under the receiving body 111 and is
against the second surface 12212 of the driving body 1221 of the
driver 122 for fixing the driver 122 between the inner surface 1111
of the receiving body 111 and the seal plate 112. Thus the
fastening member is fixed in the receiving body 111. In this
embodiment, the rotating shaft 1222 is not directly fixed on the
driver in the receiving body 111 so that a force opposite to the
rotating shaft 1222 will not be generated around a periphery of the
driver 122. And the driver 122 will not be affected by the force
and become unstable during rotation.
[0027] Back to FIG. 3, there are two insert holes 1121 on the seal
plate 112. In this embodiment, each insert hole 1121 is curved. The
driving body 1221 of the driver 122 is arranged with two driving
holes 1224. Each driving hole 1224 penetrates the driving body 1221
to the guiding member 1223, without penetrating the guiding member
1223. Thus the driving hole 1224 is a blind hole. The two insert
holes 1121 of the seal plate 112 are corresponding to the two
driving holes 1224 of the driver 122. When users want to rotate the
driver 122, a pin 2 is inserted through the insert holes 1121,
inserted into the driving holes 1224 and then moved within the
inset holes 1121 for driving the driver 122 to rotate.
[0028] When the driver 122 is rotated, the two guiding members 1223
of the driver 122 push the two driving parts 1213 of the two
fasteners 121 and the two fasteners 121 move horizontally within
the receiving body 111. While the driver 122 being rotated
counterclockwise, the two guiding members 1223 push the two driving
parts 1213 of the two fasteners 121. Thus the two fasteners 121
move toward two sides of the receiving body 111 respectively and
the fixing parts 1212 of each fastener 121 are moved to be locked
in the fastening parts 102 of the cover 10. Ad the cover 10 is
fastened on the receiving body 111. Once the driver 122 is rotated
clockwise, the two guiding members 1223 push the two driving parts
1213 of the two fasteners 121 to move toward the center of the
receiving body 111. Thus the fixing parts 1212 of each fastener 121
are released from the fastening parts 102 of the cover 10.
Therefore the cover 10 and the receiving body 11 are separated from
each other.
[0029] Still refer to FIG. 3, for linear movement of the fastener
121, the receiving body 111 is further mounted with two first
stopping parts 1115. The two first stopping parts 115 are
respectively located on two sides of the two fasteners 121 so as to
move horizontally between the two stopping parts 1115. In other
words, the stopping parts 115 are parallel to the movement
direction of the fasteners 121. Furthermore, the receiving body 111
is further disposed with two first stopping parts 1116 respectively
located on two sides of the driver 122. Two stopping members 1225
are disposed on a periphery of the driving body 1221 of the driver
122. The two stopping members 1225 are respectively located between
the two second stopping parts 1116. Also refer to FIG. 6, when the
driver 122 is rotated, the two stopping members 1225 of the driver
122 are respectively moved between the two second stopping parts
1116 so as to restrict the rotation angle of the driver 122.
Moreover, two third stopping parts 1117 are arranged at the inner
surface 1111 of the receiving body 111 and the fastening body 1211
of each fastener 121 is disposed with a positioning hole 1214. Each
third stopping part 1117 is corresponding to the positioning hole
1214 so as to limit the position of the two fasteners 121 in the
receiving body 111.
[0030] The receiving body further includes a plurality of
supporting parts 1118 arranged between the two first stopping parts
1115 and under the two fasteners 121 for supporting the two
fasteners 121. The supporting parts 1118 keep the two fasteners 121
away from the inner surface 1111 of the receiving body 111 and
reduce contact area between the two fasteners 121 and the inner
surface 1111 of the receiving body 111. Thus the friction force
between the two fasteners 121 and the inner surface 1111 of the
receiving body 111 is reduced. Therefore the two fasteners 121 move
smoothly on the inner surface 1111 of the receiving body 111.
[0031] Refer to FIG. 2, FIG. 3, FIG. 4, and FIG. 5, the driver 122
is further disposed with two pressing parts 1226 each of which is a
projecting block that projects from the first surface 12211 of the
driving body 1221. The two pressing parts 1226 respectively are
located between the two guiding members 1223. The pressing part
1225 includes a guiding surface 12261 and a positioning slot 12262.
While the driver 122 being rotated counterclockwise, one side of
the fastener 121 with the driving part 1213 is against the guiding
surface 12261 of the corresponding pressing part 1226. The guiding
surface 12261 against the surface of the driving part 1213 is moved
along the surface of the driving part 1213 along with the rotation
of the driver 122. Thus the one side of the fastener 121 with the
driving part 1213 is descended along with the guiding surface 12261
while one side of the fastener 121 with the fixing parts 1212 is
ascended. Thus the fixing parts 1212 are locked with the fastening
parts 102 of the cover 10 and the container 1 is with good
air-tightness. A ramp 12111 is disposed on one side of the driving
part 1213 of each fastener 121 that is against the pressing part
1226. The pressing part 1226 is moved along the ramp 12111 of the
fastening body 1211 to the surface of the driving part 1213 and
then moved along the surface of the driving part 1213, as shown in
FIG. 5.
[0032] Two rolling parts 1227 are mounted on the driving body 1221
of the driver 122, under the pressing part 1226. When the driver
122 is rotated, the rolling parts 1227 allow the driver not in
direct contact with the seal plate 112. Thus friction between the
driver 122 and the seal plate 112 is reduced. Moreover, the two
rolling parts 1227 are rolled along with rotation of the driver 122
so that the driver 122 is rotated stably. Thus contaminants
produced by the friction between the driver 122 and the seal plate
112 are reduced so as to protect the semiconductor device from
contamination. The rolling part 1227 of this embodiment is a
bearing and is able to be other component.
[0033] Although the two rolling parts 1227 enable the driver 122
rotating stably, there is still friction occurred between the
rolling parts 1227 and the seal plate 112. Thus there may be some
contaminants produced to contaminate the semiconductor devices. A
wear-resistant part 1122 is attached to the seal plate 112 and
located between the seal plate 112 and the two rolling parts 1227
so as to reduce friction between the rolling parts 1227 and the
seal plate 112 and minimize abrasion of the seal plate 112 caused
by the rolling parts 1227. The amount of contaminants produced is
further minimized so as to prevent contamination of the
semiconductor devices in the container 1.
[0034] Back to FIG. 6, the receiving body 111 further includes two
connecting parts 1119 respectively located on one side of the
corresponding fastener 121. The fastening body 1211 of each
fastener 121 is also disposed with a connecting member 1215. Each
connecting part 1119 is connected to the corresponding connecting
member 1215 of the fastener 121 by an elastic part 13. Each first
stopping part 1115 of the receiving body 111 includes a slot 11151
that is inserted by the corresponding elastic part 13. The length
of the elastic part 13 is shorter than the thickness of the
receiving body 111 so that the receiving body 111 is completely
closed by the seal plate 12 of the container 112. The position of
each fastener 121 being locked with the fastening parts 102 of the
cover 10 is defined as the original position of the fastener 121.
When the two fasteners 121 are moved toward the center of the
receiving body 111, the elastic part 13 is also moved toward the
center of the receiving body 111 along with the fastener 121 and
then to be stopped by one side of the slit 11151. A restoring force
is produced by the elastic part 13 due to material elasticity when
the elastic part 13 is in contact with and stopped by the side of
the slit 11151. The restoring force enables the fastener 121
turning back to the original position. When the driver 122 is not
working normally, the elastic parts 13 still make the fasteners 121
turn back to their original position. The fasteners 121 are
fastened to the fastening parts 102 of the cover 10 to prevent the
receiving 111 and the cover 10 from separating from each other.
[0035] With reference to FIG. 7, the elastic part 13 includes a
first part 131 and a second part 132 connected to the first part
131. The second part 132 is inclined downward with respect to the
first part 131 to press against the fastening body 1211 of the
fastener 121. One end of the first part 131 is disposed on the
connecting part 1119 of the receiving body 111 and one end of the
second part 132 is set on the connecting member 1215 of the
fastener 121.
[0036] When the driving part 1213 of the fastener 121 is pressed by
the pressing parts 1226, the fixing part of the fastener 1212 is
lifted and fastened to the fastening parts 102. The second part 132
of the elastic part 13 inclined downward with respect to the first
part 131 of the elastic part 13 is pressing against the fastening
body 1211 so as to make the fixing part 1212 of the fastener 12
stay in the ascended state and lock with the fastening part 102 of
the cover 10. Thus the container 1 has a high level of
air-tightness.
[0037] Refer to FIG. 8 and FIG. 9, another embodiment of the
present invention is disclosed. As shown in figure, friction occurs
between the pressing parts 1226 of the driver 122 and the driving
parts 1213, when the driver 122 is rotated and is in contact with a
part of the surface of each driving part 1213. In order to minimize
the friction between the driver 122 and the driving part 1213, a
rolling element 12110 is arranged at the driving part 1213 of the
fastener 121 where the friction occurs. Thus the rolling surface
12261 of the pressing part 1226 of the driver 122 is in contact
with the rolling element 12110 on the driving part 1213 of the
fastener 121 and the contact area between the driving part 1213 and
the pressing part 1226 is reduced. Therefore friction between the
driving parts 1213 and the pressing parts 1226 is further reduced
to minimize production of contaminants and protect the
semiconductor devices in the container.
[0038] While the driver 122 being rotated, the driver 122 drives
the rolling element 12110 to roll because that the guiding surface
12261 of the pressing part 1226 of the driver 122 is in contact
with the rolling element 12110 on the driving part 1213 of the
fastener 121. Then the rolling element 12110 is rolled and moved
along the guiding surface 12261. The positioning slot 12262 is
arranged at a rear end of the guiding surface 12261. When the
rolling element 12110 is rolled along the guiding surface 12261 and
moved to the positioning slot 12262, the rolling element 12110 is
stopped and positioned by the positioning slot 12262. Thus the
fixing part 1212 of the fastener 121 is fixed on the fastening part
102 of the cover 10. In this embodiment, the friction between the
rolling element 12110 and the guiding surface 12261 is reduced by
the rolling element 12110 rolling along the guiding surface 12261.
Thus the driver 122 smoothly drives the fastener 121 to move in the
receiving body 111 and enables the fastening member working well.
Therefore the container 1 is opened and closed smoothly. The
rolling element 12110 of this embodiment can be a bearing or other
component. The rolling element 12110 can also be applied to other
structure where the driver 122 is fastened to the receiving body
111.
[0039] In summary, the present invention provides a container for
storing semiconductor devices in which a cover is fixed on a
receiving body by a fastening member in the receiving body so as to
seal the container and protect the container from contamination.
The fastening member consists of at least one fastener and at least
one driver. The fastener and the driver are disposed on the
receiving body. The driver is fixed in the receiving body by a seal
plate against the driver instead of being fastened by screws. Thus
the driver is rotated stably. The driver is arranged with two
rolling parts that reduce contact area between the driver and the
seal plate to prevent contaminants produced by friction between the
driver and the seal plate and protect semiconductor devices stored
in the container from contamination. Moreover, a wear-resistant
part is attached to the seal plate where the seal plate is in
contact with the two rolling parts so as to reduce the amount of
contaminants produced by the friction between the rolling parts and
the seal plate and protect the semiconductor devices in the
container.
[0040] Furthermore, each fastener of the fastening member is set
with a rolling element in contact with the driver. The rolling
element is used for reducing contact area between the driver and
the fastener to minimize contaminants produced by friction between
the driver and the fastener. Thus the semiconductor devices stored
in the container will not be polluted. The rolling element is
rolled along with rotation of the driver to reduce the friction
therebetween and ensure smooth operation of the driver that drivers
the fastener to move in the receiving body. Thus the fastening
member runs smoothly and the container is opened and closed
smoothly.
[0041] Additional advantages and modifications will readily occur
to those skilled in the art. Therefore, the invention in its
broader aspects is not limited to the specific details, and
representative devices shown and described herein. Accordingly,
various modifications may be made without departing from the spirit
or scope of the general inventive concept as defined by the
appended claims and their equivalent.
