Abstract
Description
Technical Field
[0001] The present application relates to the field of semiconductor technology, and in particular to a labeling jig. Background Art
[0002] Before wafer dicing, an adhesive film (such as blue film) needs to be attached to the back of the wafer. After the adhesive film is applied, a label matching the product information, such as a label with a barcode, needs to be affixed to the edge of the adhesive film to prevent product mixing and abnormal traceability. During the subsequent dicing operation, the product information on the label can be scanned with the device's built-in scanner to export the product information.
[0003] Currently, there are two methods for labeling: machine labeling and manual labeling. Machine labeling requires the purchase of equipment, which is expensive. Manual labeling, on the other hand, is less expensive. However, manual labeling involves applying the label directly to the adhesive film, and the placement of the label can be affected by factors such as the operator's viewing angle and the different operators.

[0029] The present application provides a labeling jig for attaching labels to wafers after an adhesive film is attached, wherein a steel ring spaced from the periphery of the wafer is fixed to the adhesive film. The labeling jig includes an annular support body and a label alignment structure. The annular support body has a support groove adapted to and used to support the steel ring; the label alignment structure is connected to the support body and located on the inner side of the support body, and is used to indicate the label attachment position when the label is attached, allowing the user to attach the label on the other side of the adhesive film away from the label alignment structure. The above-mentioned labeling jig is configured to have an annular support body capable of supporting the steel ring, and the support body has a support groove adapted to and used to support the steel ring. The labeling jig also has a label alignment structure connected to the inner side of the support body, and the label alignment structure is used to indicate the label attachment position when the label is attached, allowing the user to attach the label on the other side of the adhesive film away from the label alignment structure. This can achieve low-cost manual labeling while improving the stability of the labeling position and ensuring the repeatability of the labeling position.
[0030] The following is combined with Figures 1 to 6 , some embodiments of the present application are described in detail. In the absence of conflict, the features of the following embodiments can be combined with each other.
[0031] Please refer to Figure 1 , and when necessary, combine Figures 2 to 6 As shown, the labeling jig 100 can be used to attach labels to a wafer 70 after an adhesive film 60 is attached. A steel ring 50 is fixed to the adhesive film 60 and spaced from the periphery of the wafer 70. The labeling jig 100 may include an annular support body 10 and a label alignment structure 20.
[0032] The annular supporting body 10 has a supporting groove 1001 adapted to the steel ring 50 and used to support the steel ring 50 .
[0033] The label alignment structure 20 is connected to the support body 10 and is located on the inner side of the support body 10 . It is used to indicate the pasting position of the label 90 when the label 90 is pasted, so that the user can paste the label 90 on the other side of the adhesive film 60 away from the label alignment structure 20 .
[0034] Combine Figure 3 As shown, before wafer 70 is diced, the wafer 70 can be attached to the adhesive film 60, and the adhesive film 60 can be fixed and supported by the steel ring 50 to form an intermediate structure 1000 including the wafer 70, the adhesive film 60 and the steel ring. The labeling jig 100 can be used to attach labels to the intermediate structure 1000.
[0035] The label mentioned here may be a barcode label having a barcode.
[0036] The labeling jig 100 is configured to have an annular support body 10 capable of supporting a steel ring 50. The support body 10 has a support groove 1001 that matches the outer contour of the steel ring 50 and is used to support the steel ring 50. The labeling jig 100 also has a label alignment structure 20 connected to the inner side of the support body 10. The label alignment structure 20 is used to indicate the affixing position of the label 90 when the label 90 is affixed. This allows the user to affix the label 90 to the side of the adhesive film 60 facing away from the label alignment structure 20. This achieves low-cost manual labeling while improving the stability of the labeling position and ensuring repeatability of the labeling position.
[0037] Combine Figure 2 As shown, in some embodiments, the support body 10 includes a support bottom wall 11 and a support side wall 12, the support bottom wall 11 has a first surface 101 and a second surface 102 relative to each other, the support side wall 12 is connected to the periphery of the support bottom wall 11, and extends from the first surface 101 to the side away from the second surface 102, forming the support groove 1001 on the periphery of the support body 10 and the first surface 101 of the support bottom wall 11.
[0038] In some embodiments, the height h of the supporting side wall 12 is in the range of 1.5 mm to 5 mm, so as to well limit the periphery of the steel ring 50 and facilitate the taking and placing of the steel ring.
[0039] In some embodiments, the labeling jig 100 is provided with an anti-misalignment structure for preventing the steel ring 50 from being misplaced before the wafer 70 is affixed with the adhesive film 60 , so that the labels are affixed to the same position on different intermediate structures 1000 , facilitating subsequent identification.
[0040] In some embodiments, the outer edge of the steel ring 50 has a first steel ring edge 51 and a second steel ring edge 52 that are opposite to each other and are flush. The outer edge of the steel ring 50 has two notches 501 and 502 located at both ends of the first steel ring edge 51, and the anti-dislocation structure cooperates with at least one of the two notches 501 and 502.
[0041] The anti-dislocation structure can prevent the first steel ring edge 51 and the second steel ring edge 52 from being placed upside down.
[0042] Of course, the steel ring 50 may also have two other flush steel ring edges that are perpendicular to the first steel ring edge 51 and face the second steel ring edge 52. The anti-misalignment structure can accordingly prevent the steel ring edges other than the first steel ring edge 51 from being placed on the side where the label alignment structure 20 is located.
[0043] In some embodiments, the support bottom wall 11 is provided with openings 1002 and 1003. The staggered structure includes two fixing members 30 that can be fixed to the openings 1002 and 1003 and can protrude from the first surface 101 of the support bottom wall 11.
[0044] The openings 1002 and 1003 may be provided with internal threads, and the fixing member 30 may be a bolt structure adapted to the openings, which has a simple structure and is convenient for taking and placing the intermediate structure 1000 .
[0045] In some embodiments, the label alignment structure 20 is in a strip shape, such as Figure 1 The inner ring of the supporting bottom wall 11 is circular, and the labeling jig 100 includes a connecting rib 40 for connecting the label alignment structure 20 and the supporting bottom wall 11. The connecting rib 40 is at least located on the side of the label alignment structure 20 away from the center O of the inner ring of the supporting bottom wall 11.
[0046] In some embodiments, the label alignment structure 20 has a first alignment edge 21 on the side away from the center O of the inner ring of the support bottom wall 11, and a second alignment edge 22 on the side toward the center of the inner ring of the support bottom wall 11, as well as a third alignment edge 23 and a fourth alignment edge 24 respectively connecting the two ends of the first alignment edge 21 and the second alignment edge 22.
[0047] To prevent the label 90 from being damaged during dicing, a sufficient distance needs to be maintained between the label 90 and the wafer 70 . Generally, a distance of more than 5 mm needs to be maintained between the label and the wafer.
[0048] Here, an 8-inch wafer 70 (i.e., a 200 mm diameter wafer) is used as an example. In some embodiments, the distance between the second alignment edge 22 and the center of the inner ring of the support bottom wall 11 is 105 mm to 106 mm to ensure sufficient distance between the attached label 90 and the wafer 70 to prevent damage to the label 90 during dicing.
[0049] In some embodiments, the connecting rib 40 connects the first alignment edge 21, the third alignment edge 23 and the fourth alignment edge 24, and the side edge of the connecting rib 40 facing the center O of the inner ring of the supporting bottom wall 11 is flush with the second alignment edge 22.
[0050] Accordingly, the area inside the ring of the supporting bottom wall 11 except the connecting ribs 40 and the label alignment structure 20 may be a hollow structure, for example Figure 1 The hollow area 1004 shown is advantageous for saving material.
[0051] Of course, in some other embodiments, the area within the ring of the supporting bottom wall 11 except for the connecting ribs 40 and the label alignment structure 20 may also be a solid structure.
[0052] It should be noted that the label alignment structure 20 can be integrally formed with the connecting rib 40. Alternatively, the surface of the connecting rib 40 can be provided with an inner groove, and the label alignment structure 20 can be correspondingly positioned within the inner groove. The label alignment structure 20 and the connecting rib are substantially flush with the surface on the same side as the first surface of the supporting bottom wall 11.
[0053] In other embodiments, the connecting rib 40 surrounds the label alignment structure 20, and the side edge of the connecting rib 40 facing the center O of the inner ring of the support bottom wall 11 is closer to the center O of the inner ring of the support bottom wall 11 than the second alignment edge, which can greatly improve the strength of the label alignment structure and increase the service life of the labeling jig.
[0054] In some embodiments, the entire surface area of the label alignment structure 20 is a striking color or the outer contour surface of the label alignment structure 20 is a striking color.
[0055] In some embodiments, the eye-catching color is red. The inventors have found through research that when the surface area of the label alignment structure 20 or the external force contour surface is red, the labeling area corresponding to the label alignment structure 20 observed by the operator during alignment labeling is clearer.
[0056] It should be noted that the adhesive film 60 mentioned here is a transparent or translucent film layer, such as a blue film or a white transparent film.
[0057] Based on the above description of the labeling fixture 100, combined with Figures 3 to 6 For 100 pairs of the above labeling fixtures Figure 3 The intermediate structure 1000 including the wafer 70, the adhesive film 60 and the steel ring 50 is illustrated for labeling operation. Figure 4 The intermediate structure 1000 can be placed in the support groove 1001 of the labeling fixture 100, with the wafer 70 facing away from the first surface 101 of the support bottom wall 11, and the adhesive film 60 facing the first surface 101. The fixing member 30 can be correspondingly placed in the openings 1002 and 1003 to define the position of the steel ring 50. In this way, the position of the label alignment structure 20 can be checked from the surface of the adhesive film 60 facing away from the label alignment structure 20. Then, the label 90 is attached to the corresponding position of the surface of the adhesive film 60 facing away from the label alignment structure 20, as shown in FIG. Figure 5 Finally, the entire assembly structure 2000 with the label 90 attached thereto can be separated from the labeling fixture 100. At this point, the labeling operation is completed.
