[0026] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] The embodiment of the present application provides a material box of a semiconductor structure. The material box of the semiconductor structure includes a material box body and a limiting device. The material box body has an internal accommodating cavity, the material box body has two ends that are mutually opposed in the length direction L, and the accommodating cavity has a first opening and a second opening respectively located at the two ends; the limiting device is arranged on the material box body, including a first limiting member, a second limiting member, and a driving component connected to the first limiting member and the second limiting member; under the drive of the driving component, the first limiting member can move to the first opening, the second limiting member can move to the second opening, and the first limiting member can move away from the first opening, and the second limiting member can move away from the second opening; when the first limiting member moves to the first opening and the second limiting member moves to the second opening, the semiconductor structure in the accommodating cavity can be limited to the accommodating cavity, and when the first limiting member moves away from the first opening and the second limiting member moves away from the second opening, the semiconductor structure can move into the accommodating cavity from one of the first opening and the second opening, or move out of the accommodating cavity from the first opening and the second opening. The arrangement of the upper limit device on the material box of the semiconductor structure facilitates the sealing and removal of the semiconductor structure at the first opening and the second opening, and can prevent the semiconductor structure from slipping.

[0028] The following is combined with Figures 1 to 4 The material box of the semiconductor structure is described in detail.

[0029] First, please refer to Figure 1 , and when necessary, combine Figure 2 and Figure 4 As shown, a semiconductor structure material box 100, the semiconductor structure material box 100 comprises a material box body 10 and a limiting device. The material box body 10 has an internal accommodating cavity 1003, the material box body 10 has two ends that are separated from each other in the length direction L, and the accommodating cavity 1003 has a first opening 1001 and a second opening 1002 respectively located at the two ends.

[0030] The limiting device is provided on the magazine body 10, and includes a first limiting member 21, a second limiting member 22, and a driving assembly 23 drivingly connected to the first limiting member 21 and the second limiting member 22. Under the drive of the driving assembly 23, the first limiting member 21 can move to the first opening 1001, the second limiting member 22 can move to the second opening 1002, and the first limiting member 21 can move away from the first opening 1001, and the second limiting member 22 can move away from the second opening 1002. When the first limiting member 21 moves to the first opening 1001 and the second limiting member 22 moves to the second opening 1002, the semiconductor structure in the accommodating cavity 1003 can be limited in the accommodating cavity 1003; when the first limiting member 21 moves away from the first opening 1001 and the second limiting member 22 moves away from the second opening 1002, the semiconductor structure can move into the accommodating cavity 1003 from one of the first opening 1001 and the second opening 1002, or move out of the accommodating cavity 1003 from the first opening 1001 and the second opening 1002.

[0031] Here, the first stopper 21 moving to the first opening 1001 can be understood as the first stopper 21 at least blocking the middle area of ​​the first opening 1001, for example Figure 2 Similarly, the second stopper 22 moving to the second opening 1002 can be understood as the second stopper at least blocking the middle area of ​​the second opening 1002, such as Figure 2 That is, the first limiting member 21 and the second limiting member 22 move to a position where they can limit the semiconductor structure in the accommodating cavity 1003 and prevent the semiconductor structure from falling out of the accommodating cavity 1003 .

[0032] The first limiting member 21 moving away from the first opening 1001 mentioned here can be understood as the first limiting member 21 moving from the middle area of ​​the first opening 1001 to the edge area (for example Figure 1 shown in the position) or move to the outside of the cartridge body 10 (e.g. Figure 3 Similarly, the second stopper 22 moves away from the second opening 1002, which can be understood as the second stopper 22 moving from the middle area of ​​the second opening 1002 to the edge area (such as Figure 1 shown in the position) or move to the outside of the cartridge body 10 (e.g. Figure 3 The position shown in the figure) does not hinder the position where the semiconductor structure passes through the second opening 1002.

[0033] Here, the first limiting member 21 and the second limiting member 22 may be as follows Figure 1The bent rod-shaped limiting structure shown, the first limiting member 21 and the second limiting member 22 have simple structures, are easy to manufacture, move and operate, and are relatively cost-effective. Of course, in some other embodiments, the first limiting member and the second limiting member can also be plate-shaped or other shaped structures that can limit the semiconductor structure located in the accommodating cavity 1003.

[0034] like Figure 1 As shown, in some embodiments, the first limiting member 21 and the second limiting member 22 are rotatably provided on the material box body 10, and the driving assembly 23 drives the first limiting member 21 and the second limiting member 22 to rotate, so that the first limiting member 21 moves to the first opening 1001, the second limiting member 22 moves to the second opening 1002, or the first limiting member 21 moves away from the first opening 1001, and the second limiting member 22 moves away from the second opening 1002.

[0035] The first limiting member 21 and the second limiting member 22 may include a limiting body and a connecting portion connecting the limiting body and the driving assembly 23. Figure 1 The second limiting member 22 shown in the figure includes a limiting body 221 and a connecting portion 222. The driving assembly 23 drives the connecting portion to rotate, so that the limiting body rotates with the rotation of the connecting portion. The limiting body is mainly used to limit the semiconductor structure located in the accommodating cavity 1003.

[0036] It is understandable that in some other embodiments, the first limiting member and the second limiting member may also be moved to the first opening and the second opening, or moved away from the first opening and the second opening, by other means such as translation.

[0037] In some embodiments, the limiting device further comprises a transmission assembly connected between the driving assembly 23 and the first limiting member 21 , and between the driving assembly 23 and the second limiting member 22 .

[0038] The transmission assembly mentioned here can be a transmission gear assembly, or a combination structure formed by a transmission gear and a connecting rod and other structures.

[0039] In some embodiments, the material box body 10 has a first wall 101 for forming the accommodating cavity 1003, and a second wall 102 and a third wall 103 connected to the first wall 101 and the opposite sides. The driving assembly 23 and the transmission assembly are both arranged on the first wall 101, and the first limit member 21 and the second limit member 22 are rotatably arranged on the first wall 101 through the rotating shaft 2101 respectively.

[0040] When the first limiting member 21 moves away from the first opening 1001, the first limiting member 21 is located outside one end portion between the second wall 102 and the third wall 103; when the second limiting member 22 moves away from the second opening 1002, the second limiting member 22 is located outside one end portion between the second wall 102 and the third wall 103.

[0041] In some embodiments, the first wall 101 is the top wall of the semiconductor structure material box 100. The first wall 101 is the top wall, which is convenient for the arrangement of the limiting device and the driving component 23 to perform the driving operation.

[0042] In some embodiments, the driving assembly 23 includes a driving gear 231 , a first driven gear 210 is disposed on the rotating shaft of the first limiting member 21 , and a second driven gear 220 is disposed on the rotating shaft of the second limiting member 22 .

[0043] The transmission assembly includes a first transmission assembly 31 connected between the driving gear 231 and the first driven gear 210, and a second transmission assembly 32 connected between the driving gear 231 and the second driven gear; when the driving gear 231 rotates, the first driven gear rotates to drive the first limit member 21 to rotate, and the second driven gear 220 rotates to drive the second limit member 22 to rotate through the transmission of the first transmission assembly 31 and the second transmission assembly 32.

[0044] like Figure 1 As shown, the first transmission assembly 31 includes a transmission rod 313, transmission gears 311 and 314 rotatably disposed at both ends of the transmission rod 313, and a mounting shaft 312. The transmission gear 314 meshes with the first driven gear 210, and the transmission gear 311 meshes with the driving gear 231. The transmission rod 313 is rotatably mounted on the first wall 101 through the mounting shaft 312.

[0045] The second transmission assembly 32 includes a transmission rod 323, transmission gears 321 and 324 rotatably disposed at both ends of the transmission rod 323, and a mounting shaft 322. The transmission gear 324 meshes with the second driven gear 220, and the transmission gear 321 meshes with the driving gear 231. The transmission rod 323 is rotatably mounted on the first wall 101 via the mounting shaft 322.

[0046] It should be noted that the first position-limiting member 21 and the second position-limiting member 22 are driven to move synchronously by the same driving assembly 23, and the overall structure of the driving assembly is relatively simple, and the driving operation is also relatively simple. In some other embodiments, the driving assembly may also include two driving structures for driving the first position-limiting member and the second position-limiting member to move, respectively, so as to drive the first position-limiting member and the second position-limiting member to move.

[0047] In some embodiments, the driving assembly 23 further includes an operating member connected to the driving gear 231 , and the operating member can drive the driving gear 231 to rotate along a first direction R1 or a second direction R2 opposite to the first direction R1 when subjected to an external force.

[0048] In some embodiments, the operating member is a rotatable operating handle 232, and the operating handle 232 has different first positions and second positions. When the operating handle 232 is rotated to the first position, the first limiting member 21 is outside the first opening 1001, and the second limiting member 22 is outside the second opening 1002. When the operating handle 232 is rotated to the second position, the first limiting member 21 is located at the first opening 1001, and the second limiting member 22 is located at the second opening 1002.

[0049] for example Figure 1 As shown, the position of the operating handle 232 may be the first position. Figure 2 As shown, the position of the operating handle 232 is the second position.

[0050] In some embodiments, at least one of the second wall 102 and the third wall 103 is provided with two receiving grooves extending along the height direction H of the semiconductor structure magazine 100 to receive the first limiting member 21 and the second limiting member 22 respectively.

[0051] like Figures 1 to 3 As shown, the second wall 102 is provided with a first receiving groove 1021 extending along the height direction H of the semiconductor structure magazine 100. The third wall 103 is provided with a second receiving groove 1022 extending along the height direction H of the semiconductor structure magazine 100. The first receiving groove 1021 and the second receiving groove 1022 are respectively close to the two ends of the length direction L of the semiconductor structure magazine 100, and the first receiving groove 1021 is used to receive the first limiter 21, and the second receiving groove 1022 is used to receive the second limiter 22.

[0052] In some embodiments, the operating handle also has a third position, and the third position and the second position are located on opposite sides of the first position. When the operating handle is located at the third position, one of the first limiting member 21 and the second limiting member 22 is located in the first receiving groove 1021, and the other is located in the second receiving groove 1022.

[0053] for example Figure 3 As shown, the position of the operating handle 232 may be the third position.

[0054] Combination Figures 1 to 3As shown, based on the above description of the semiconductor structure cartridge 100, during use of the semiconductor structure cartridge 100, the initial position of the operating handle 232 can be as follows: Figure 3 The operating handle 232 is in the third position as shown. When the operating handle is in this position, the first limiting member 21 and the second limiting member 22 are in the storage state. The operating handle 232 can rotate from the initial position along the first direction R1 to the position as shown. Figure 1 The operating handle 232 can be moved from the second position to the first position and the third position along the second direction R2. Figure 1 The first position shown is the middle position. When the operating handle 232 is in the middle position, the semiconductor structure can be loaded into or removed from the material box 100. Figure 2 In the second position shown, the first limiting member 21 and the second limiting member 22 are located in the middle regions of the first opening 1001 and the second opening 1002 respectively, that is, at the positions for shielding the semiconductor structure.

[0055] It is understandable that the operating handle 232 can also move or stay at any position between the second position and the third position other than the first position.

[0056] It should be noted that if Figures 1 to 3 In the illustrated embodiment, the first limiting member 21 and the second limiting member 22 rotate in the same direction during operation, and the first limiting member 21 and the second limiting member 22 are received outside two different second walls 102 and third walls 103 .

[0057] In some other embodiments, the first stopper and the second stopper can also be arranged to rotate in opposite directions, and when stored, they are stored outside the same wall of the second wall 102 and the third wall 103. Accordingly, the driving gear 231 can be arranged as two meshing gears, and the two gears are respectively used to drive the first stopper 21 to rotate and the second stopper 22 to rotate. The operating handle can be arranged on one of the gears and rotate synchronously with the arranged gear.

[0058] In addition, if Figure 4 As shown, in other embodiments, the semiconductor structure material box 200 may also have two limiting structures 40, which are used to position the operating handle 232 at the second position and the third position respectively. The limiting structure may be a limiting button, which is in a pressed state during the rotation of the operating handle 232, and does not hinder the rotation of the operating handle 232. When the operating handle 232 is at the second position or the third position, it pops up accordingly to limit the operating handle 232.

[0059] It should be noted that in the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It is also understood that when an element or layer is referred to as being "on" another element or layer, it may be directly on the other element, or there may be an intermediate layer. In addition, it is understood that when an element or layer is referred to as being "under" another element or layer, it may be directly under the other element, or there may be more than one intermediate layer or element. In addition, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it may be the only layer between the two layers or two elements, or there may also be more than one intermediate layer or element. Similar reference numerals throughout the text indicate similar elements.
