In the Back end process of fig. 3-8, the semiconductor product 10 is located on the chase 4, and the chase 4 carries the semiconductor product 10 into the apparatus for the process. Since the semiconductor product 10 is firmly mounted on the iron frame 4, and the iron frame 4 and the product are symmetrical, the iron frame 4 can be manually taken and placed only by manpower when being placed in the square carrying box-front opening wafer transfer box (Front Opening Unified Pod, FOUP) -and can be manually checked whether to be reversed or not, no engineering confirmation means is found, and when the semiconductor product 10 is placed in the FOUP in the opposite direction during self-inspection, the door of the FOUP can be normally closed, but if the iron frame 4 is placed in the FOUP in the form of being faced downwards upwards, the machine can cause damage such as scratch and the like to the semiconductor product 10 when the semiconductor product 10 is taken out from the FOUP, and the yield of the semiconductor product 10 is reduced.

In the future, large-sized Fan-out (Fan out) panel products will gradually develop, and rectangular panel-level thinned products with 600mm and 300mm are not popular in the semiconductor industry, and the problem of low use universality exists in the process equipment, jigs (such as FOUP, metal bearing box and the like) used correspondingly by the equipment, and materials are required to be customized and developed and evaluated.

The embodiment of the application solves the problem that the directivity of the carrier 20 is not easy to determine by forming the first limiting structure 31 on the carrier 20 and the body 22 is an asymmetric structure.

Fig. 10 shows a perspective view of the carrier box 40 according to an embodiment of the present application, fig. 11 shows an internal plan view when the carrier 20 shown in fig. 9 and the semiconductor product 10 are located in the carrier box 40, and fig. 12 shows a schematic structural view of the inner side (second side wall 42) of the front cover 80 of the carrier box 40.

Fig. 14 to 19 show embodiments different from fig. 13, in which the first and second limit structures 31, 32 in fig. 14 may be asymmetrical with respect to the virtual center line 228, or with respect to the virtual center line 228, since the asymmetry of the body 22 is ensured by providing a third limit structure 33 of a different shape located to the left of the virtual center line 228; the embodiment of fig. 15 guarantees an asymmetry of the body 22 by the different shapes of the first and second limit structures 31, 32; the embodiment of fig. 16 ensures the asymmetry of the body 22 by the different shape, position asymmetry of the first and second limit structures 31, 32; the embodiment of fig. 17 ensures the asymmetry of the body 22 by the different sizes of the first and second limit structures 31, 32; the embodiment of fig. 18 ensures asymmetry of the body 22 by providing the first limit structure 31 only to the right of the virtual center line 228; the embodiment of fig. 19 ensures an asymmetry of the body 22 by the different shapes of the first and second limit structures 31, 32.

In the embodiment of fig. 15 to 17, 19, the carrier 20 further comprises: the second limiting structure 32 is disposed on the second side of the body 22 asymmetrically with respect to the first limiting structure 31 based on the virtual center line 228.

In the embodiment of fig. 15 to 16, 19, the carrier 20 further comprises: the second limiting structure 32 is disposed on the second side of the body 22 with reference to the virtual center line 228, and the outer contour of the second limiting structure 32 and the outer contour of the first limiting structure 31 are different in geometric contour when viewed from the top view, and includes: the shape and the size are different; or the same shape but different sizes.

In the embodiment of fig. 17, the outer contour of the second limiting structure 32 is the same as the outer contour of the first limiting structure 31 in shape and different in size.

In the embodiment of fig. 15 to 16 and 19, the outer contour shape of the second limiting structure 32 is different from the outer contour shape of the first limiting structure 31.

In the embodiment of fig. 13-17 and 19, the second stop structure 32 is disposed on the first edge 221.

In the embodiment of fig. 13-19, the first and second stop structures 31, 32 are grooves recessed from the first edge 221.

In some embodiments, the distance between the limiting member 70 and the center point of the circular product 10 is greater than or equal to the radius of the circular product/semiconductor product 10, that is, the limiting member 70 does not touch or interfere with the circular product 10, and does not affect the taking and placing of the circular product 10.

In the embodiment of fig. 16, a stop 70 is provided on the third side wall 43. The round product 10 is in contact with the stop 70.

In the embodiment of fig. 14, the stopper 70 is provided on the first side wall 41. The stopper 70 is provided on the first side wall 41 and is provided side by side with the abutting piece 60.

In the embodiment of fig. 13 and 14, the limiting member 70 is disposed on the body 22 of the carrying case 40, and the limiting member 70 and the square product 20 are in a concave-convex structure 82.

When a plurality of carriers 20 are put into the respective layer accommodating spaces of the carrier box 40, even if only one direction of the carriers 20 is reversed, it is clearly observed that the reversed carrier 20 is not engaged with the stopper 70 when the front cover 80 of the carrier box 40 is covered. However, if all the carriers 20 are reversed, i.e. all the upper surfaces of the carriers 20 are facing downward, the front cover 80 is only likely to be covered if rotated 180 °, and the operator can obviously perceive that the direction is incorrect, the entire product of the carrier case 40 is reversed, and the stop 70 on the front cover 80 and the asymmetric third stop structure 33 are the last line of confirmation defense.

Referring to fig. 12, the second side wall 42 of the front cover 80 has a concave-convex structure 82 cooperating with the supporting frame 50, and when the carrier 20 is accommodated in the carrier box 40, the carrier 20 is located between the concave-convex structures 82.

In the embodiment of fig. 14, the shape of the abutment 60 and the stop 70 are different.

Embodiments of the present application provide a design of a carrier/square product 20 that carries a semiconductor product 10 (e.g., a panel-level package) as a chase and a carrier box 40 that is mutually restrained. The carrier 20 and carrier box 40 of embodiments of the present application may be used for panel-level packages (PANEL LEVEL PACKAGE, PLP) with a 300 x 300mm size panel, 300 x 300mm size wafer, fan-out, or Fan-in.
