Description

Technical Field

[0001] The invention relates to a packaging process monitoring system and a packaging process monitoring method. Background Art

[0002] After the wafers undergo manufacturing, yield testing, and appearance inspection before shipment, they are shipped to the wafer foundry or the customer's wafer sales office according to product requirements. In the wafer packaging process, the corresponding customer labels and information are printed and affixed to the wafer shipping box (for example, the front opening shipping box (FOSB)) and the barrier bag for identification. The factory has now introduced a fully automatic wafer packaging process. However, in the packaging process, the printed and affixed labels are divided into inner labels (affixed to the wafer shipping box) and outer labels (affixed to the barrier bag). After the packaging process is completed, the production line personnel can only confirm the outer label, while the inner label needs to be checked one by one by the personnel opening the barrier bag.

[0047] Step S201: Put materials into the material box MB.

[0048] Please refer to Figure 3 . Figure 3FIG. 1 is a schematic diagram of a material box MB containing a wafer W according to an embodiment of the present invention. In this embodiment, the material is placed in the material box MB. In some embodiments, the material may be a wafer W, such as Figure 3 More specifically, the packaging device 110 places the wafer W into the material box MB.

[0049] In some embodiments, the material box MB may be a front opening shipping box (FOSB). In some other embodiments, the material box MB may be a front opening wafer transfer box (FOUP) or other suitable containers.

[0050] Step S202: Printing the barcode BC on the first label TG1 and the second label TG2.

[0051] Please refer to Figure 3 as well as Figure 4 . Figure 4 According to one embodiment of the present invention, a barrier bag BB is used for packaging. Figure 3 Schematic diagram of a material box MB in which a wafer W is placed. Figure 3 as well as Figure 4 As shown, in this embodiment, the barcode BC is printed on the first tag TG1 and the second tag TG2. Each of the first tag TG1 and the second tag TG2 may include a plurality of barcodes BC printed thereon. More specifically, the printing device 120 prints one or more barcodes BC on each of the first tag TG1 and the second tag TG2.

[0052] In some embodiments, the step of printing the barcode BC on the first label TG1 and the second label TG2 (ie, step S202 ) is performed after the step of placing the material in the material box MB (ie, step S201 ).

[0053] In one usage scenario, after the packaging device 110 places the wafer W in the material box MB, the printing device 120 prints the barcode BC on the first label TG1 and the second label TG2 .

[0054] Step S203: Paste the first label TG1 on the material box MB.

[0055] Please continue to refer to Figure 3 In this embodiment, the first label TG1 is affixed to the material box MB. Specifically, the first label TG1 is affixed to the outer surface of the material box MB. Figure 3 As shown, the first label TG1 printed with the barcode BC is attached to the material box MB. More specifically, the labeling device 130 attaches the first label TG1 to the material box MB.

[0056] In some embodiments, the step of attaching the first label TG1 to the material box MB (ie, step S203 ) is performed after the step of printing the barcode BC on the first label TG1 and the second label TG2 (ie, step S202 ).

[0057] In one usage scenario, after the printing device 120 prints the barcode BC on the first label TG1 and the second label TG2 , the labeling device 130 affixes the first label TG1 on the material box MB.

[0058] In some embodiments, the method M further includes attaching a blank RFID label to the material box MB. After executing step S203, the labeling device 130 attaches the blank RFID label to the material box MB. Figure 3 As shown, in some embodiments, the previous electronic label RFID is affixed to the material box MB. Therefore, the labeling device 130 removes the previous electronic label RFID on the material box MB and affixes a blank RFID label without any barcode on the material box MB.

[0059] Step S204: Capture a first image of the first tag TG1 including the barcode BC.

[0060] Please refer to Figure 5 . Figure 5 Schematic diagram of a first tag TG1 or a second tag TG2 according to an embodiment of the present invention. Figure 5 As shown, in this embodiment, the first image of the first tag TG1 is captured. More specifically, the image capture device 140 captures the first image of the first tag TG1. Figure 5 As shown, the first image of the first label TG1 includes a text portion TX and a pattern portion ICN. In some embodiments, the text portion TX includes a batch number, a product number, product quantity information, and customer information. The text portion TX at least provides information on where the wafer W is processed, the identification of the wafer W, the quantity of the wafer W, and where the wafer W is shipped. The pattern portion ICN includes one or more barcodes BC as described above. The barcode BC at least includes the information shown in the text portion TX. In other words, the image capture device 140 captures the text portion TX and the pattern portion ICN of the first image of the first label TG1.

[0061] In some embodiments, the step of capturing the first image of the first label TG1 including the barcode BC (ie, step S204 ) is performed after the step of attaching the first label TG1 to the material box MB (ie, step S203 ).

[0062] In a usage scenario, after the labeling device 130 affixes the first label TG1 to the material box MB, the image capturing device 140 captures a first image of the first label TG1 , and the first image includes the barcode BC of the pattern part ICN and the text of the text part TX.

[0063] Step S205: Packing the material box MB with a barrier bag BB.

[0064] Please continue to refer to Figure 4 .like Figure 4 As shown, in this embodiment, the material box MB is packaged by a barrier bag BB. Figure 3 As shown, the material box MB contains the wafer W. More specifically, the packaging device 110 packages the material box MB with the barrier bag BB. The barrier bag BB wraps the material box MB in which the wafer W is placed.

[0065] In some embodiments, the barrier bag BB may be a moisture-proof bag, an aluminum bag, an antistatic bag, a transparent bag, or the like. The present invention is not intended to be limited to the type of the barrier bag BB.

[0066] In some embodiments, the step of capturing the first image of the first tag TG1 including the barcode BC (ie, step S204 ) is performed before the step of packaging the material box MB with the barrier bag BB (ie, step S205 ).

[0067] In one usage scenario, after the image capturing device 140 captures the first image of the first label TG1 including the barcode BC, the packaging device 110 packages the material box MB with the barrier bag BB.

[0068] Step S206: affix the second label TG2 on the barrier bag BB.

[0069] Please continue to refer to Figure 4 In this embodiment, the second label TG2 is affixed to the barrier bag BB. Specifically, the second label TG2 is affixed to the outer surface of the barrier bag BB. Figure 4 As shown, the second label TG2 printed with the barcode BC is attached to the barrier bag BB. More specifically, the labeling device 130 attaches the second label TG2 to the barrier bag BB.

[0070] In some embodiments, the number of the first tag TG1 and the number of the second tag TG2 may be plural. In some embodiments, the number of the first tag TG1 and the number of the second tag TG2 may be the same. The present invention is not intended to limit the number of the first tag TG1 and the number of the second tag TG2.

[0071] In some embodiments, the step of attaching the second label TG2 to the barrier bag BB (i.e., step S206) is performed after the step of packaging the material box MB with the barrier bag BB (i.e., step S205). In some embodiments, the step of capturing the first image of the first label TG1 including the barcode BC (i.e., step S204) is performed before the step of attaching the second label TG2 to the barrier bag BB (i.e., step S206).

[0072] In one usage scenario, after the packaging device 110 packages the material box MB with the barrier bag BB, the labeling device 130 labels the second label TG2 on the barrier bag BB.

[0073] Step S207: Capture a second image of the second tag TG2 including the barcode BC.

[0074] Please continue to refer to Figure 5 In this embodiment, the second image of the second tag TG2 is captured. More specifically, the image capturing device 140 captures the second image of the second tag TG2. Figure 5 As shown, the second image of the second tag TG2 also includes the text portion TX and the pattern portion ICN shown in the first image of the first tag TG1. In other words, the image capture device 140 captures the text portion TX and the pattern portion ICN of the second image of the second tag TG2.

[0075] In some embodiments, the step of capturing the second image of the second label TG2 including the barcode BC (i.e., step S207) is performed after the step of attaching the second label TG2 to the barrier bag BB (i.e., step S206). In some embodiments, the step of capturing the second image of the second label TG2 including the barcode BC (i.e., step S207) is performed after the step of capturing the first image of the first label TG1 including the barcode BC (i.e., step S204).

[0076] In a usage scenario, after the labeling device 130 affixes the second label TG2 to the barrier bag BB, the image capturing device 140 captures a second image of the second label TG2 , and the second image includes the barcode BC of the pattern part ICN and the text of the text part TX.

[0077] Step S208: Identify the first image and the second image.

[0078] Please refer to Figure 6 , Figure 7 as well as Figure 8 . Figure 6 It is a schematic diagram of identifying whether a first image and a second image match a reference text TXR according to an embodiment of the present invention. Figure 7It is a schematic diagram of identifying whether a first image and a second image are consistent with a reference format FMR according to an embodiment of the present invention. Figure 8 Schematic diagram of determining whether the clarity of the first image and the clarity of the second image are greater than the clarity of the reference image IMGR according to an embodiment of the present invention. In this embodiment, the first image and the second image are identified. More specifically, the server 150 identifies the first image of the first tag TG1 and the second image of the second tag TG2. Figure 5 As shown, the server 150 identifies whether the pattern portion ICN of the first image and the pattern portion ICN of the second image are readable. For example, the server 150 substantially identifies the barcode BC of the first image and the barcode BC of the second image. This ensures that the customer can further utilize the material box MB with a usable (i.e., readable) barcode BC.

[0079] In some embodiments, the server 150 may recognize the text portion TX of the first image of the first tag TG1 and the text portion TX of the second image of the second tag TG2 by applying optical character recognition (OCR) or other suitable methods. The present invention is not intended to limit the method of recognizing the first image and the second image.

[0080] like Figure 6 As shown, the server 150 identifies whether both the first image and the second image match the reference text TXR. More specifically, the server 150 may record the information of the wafer W in advance, and then store the information of the wafer W in the server 150 as reference data (e.g., reference text TXR). In one usage scenario, the server 150 determines whether the lot number (i.e., Figure 6 The “Lot-ID” shown is the same as the lot number printed on the first label TG1 and the second label TG2.

[0081] like Figure 7 As shown, the server 150 identifies whether both the first image and the second image conform to the reference format FMR. More specifically, the server 150 may pre-record the formats of the first tag TG1 and the second tag TG2, and then store the formats of the first tag TG1 and the second tag TG2 in the server 150 as reference data (e.g., the reference format FMR). In a usage scenario, the server 150 determines the layout of the reference format FMR (i.e., Figure 7 The rectangular box shown in FIG. 1 is the same as the layout of the first tag TG1 and the second tag TG2, such as Figure 7 shown.

[0082] like Figure 8As shown, the server 150 determines whether the clarity of the first image and the clarity of the second image are both greater than the clarity of the reference image IMGR. More specifically, the server 150 can record the image of the historical tag pre-captured by the image capture device 140, and then store the image of the historical tag in the server 150 as reference data. Of course, the image of the historical tag has at least a resolution higher than the minimum resolution that the server 150 can recognize. In addition, the server 150 also calculates the resolution of the image of the historical tag. In one usage scenario, the server 150 determines whether the resolution of the first image and the resolution of the second image are both greater than or equal to the resolution of the reference image IMGR, such as Figure 8 shown.

[0083] In some embodiments, the step of identifying the first image and the second image (ie, step S208 ) is performed after the step of capturing the second image of the second tag TG2 including the barcode BC (ie, step S207 ).

[0084] In a usage scenario, after the image capturing device 140 captures the second image of the second tag TG2 including the barcode BC, the server 150 recognizes the first image and the second image.

[0085] Step S209: If at least one of the first image and the second image is identified as unreadable, a warning is issued.

[0086] Please continue to refer to Figure 6 , Figure 7 as well as Figure 8 In this embodiment, if at least one of the first image and the second image is identified as unreadable, an alert is issued accordingly. More specifically, if at least one of the first image and the second image is identified as unreadable, the server 150 issues an alert. That is, an alert is issued if at least one of the following conditions is met: both the first image and the second image are identified as unreadable; the first image is readable, while the second image is unreadable; the first image is unreadable, while the second image is readable. Otherwise, if both the first image and the second image are identified as readable, no alert is issued.

[0087] like Figure 6 As shown, if at least one of the first image and the second image does not match the reference text TXR, the server 150 determines that the material box MB corresponding to the first image and the second image is an error product and issues a warning. In other words, if at least one of the first image and the second image does not match the reference text TXR, the server 150 determines that the material box MB containing the wafer W is an error product and issues a warning.

[0088] like Figure 7 As shown, if at least one of the first image and the second image does not conform to the reference format FMR, the server 150 determines that the material box MB corresponding to the first image and the second image is an incorrect product and issues a warning. In other words, if at least one of the first image and the second image does not conform to the reference format FMR, the server 150 determines that the material box MB containing the wafer W is an incorrect product and issues a warning.

[0089] like Figure 8 As shown, if at least one of the clarity of the first image and the clarity of the second image is less than the clarity of the reference image IMGR, the server 150 determines that the material box MB corresponding to the first image and the second image is an incorrect product and issues a warning. In other words, if at least one of the clarity of the first image and the clarity of the second image is less than the clarity of the reference image IMGR, the server 150 determines that the material box MB containing the wafer W is an incorrect product and issues a warning.

[0090] In summary, if at least one of the following conditions is met, the material box MB is judged as an incorrect product: at least one of the first image and the second image does not match the reference text TXR; at least one of the first image and the second image does not match the reference format FMR; at least one of the clarity of the first image and the clarity of the second image is less than the clarity of the reference image IMGR.

[0091] In some embodiments, the step of issuing an alert if at least one of the first image and the second image is identified as unreadable further comprises sending an error email. For example, the error email is sent to a user of the packaging process monitoring system 100 (e.g., a technical assistant (TA), an operator, a manager, a gatekeeper, or the like).

[0092] In some embodiments, the step of issuing an alert if at least one of the first image and the second image is identified as unreadable further includes sending an error code of the wrong product to the server 150. For example, the server 150 can record the error code of the wrong product so that the user of the packaging process monitoring system 100 can find and take away the wrong product from the end of the production line, thereby preventing the wrong product from being shipped to the customer.

[0093] In some embodiments, if at least one of the first image and the second image is identified as unreadable, the step of issuing an alarm (ie, step S209 ) is performed after the step of identifying the first image and the second image (ie, step S208 ).

[0094] In a usage scenario, after the server 150 recognizes the first image and the second image, if at least one of the first image and the second image is recognized as unreadable, the server 150 issues a warning.

[0095] In some embodiments, the method M can be implemented by sequentially executing step S201, step S202, step S203, step S206, step S204, step S207, step S205, step S208, and step S209. That is, the labeling device 130 respectively affixes the first label TG1 and the second label TG2 to the material box MB and the barrier bag BB, and then the image capture device 140 captures the first image and the second image. Then, the server 150 finally recognizes the first image and the second image.

[0096] By implementing the present invention Figure 2 In the method M shown, the packaging process monitoring system 100 can monitor the packaging process and find out the wrong products on the production line.

[0097] From the above detailed description of the specific embodiments of the present invention, it can be clearly seen that in the packaging process monitoring system and the packaging process monitoring method of the present invention, since the method includes identifying the first image and the second image, the packaging process monitoring system can effectively manage the status of the first label and the second label of the material box. In the packaging process monitoring system and the packaging process monitoring method of the present invention, since the step of capturing the first image of the first label containing the barcode is performed before the step of packaging the material box with the barrier bag, the first image of the first label can be captured for identification before the material box is sealed, thereby eliminating the step of removing the barrier bag from the wrong product to check the first label one by one. In the packaging process monitoring system and the packaging process monitoring method of the present invention, since the image capture device can capture the images of the first label and the second label, the cost of manually checking the product by personnel can be reduced. In the packaging process monitoring system and the packaging process monitoring method of the present invention, since the method includes identifying the consistency of the text, pattern and format between the first label, the second label and the reference data, the situation that the barcode on the label cannot be read by the client device will be greatly reduced. In summary, the packaging process monitoring system and the packaging process monitoring method of the present invention not only improve the efficiency of the packaging process, but also avoid the huge losses caused by the return of products with incorrect labels after being shipped to customers.
