DETAILED DESCRIPTION

[0015] Please referring to FIG. 1, a smart manufacturing controlling system 1000 is shown. The smart manufacturing controlling system 1000 includes a plurality of inspection apparatuses 100*, 100 and a recipe verifying server 200. The inspection apparatus 100*, 100 may be a wafer automatic optical inspection apparatus, an optical microscope apparatus or a die cutting appearance inspection apparatus. The inspection apparatuses 100*, 100 are used to inspect any pollution, scratch, metal residue, photoresist residue or edge chipping. Due to the pattern on one lot of the wafers WF is unique, the engineer must create a particular inputting recipe RP1 to operate the inspection apparatuses 100 for those wafers WF.

[0016] For example, the engineer may create the inputting recipe RP1 via the inspection apparatus 100*, and then upload the inputting recipe RP1 to the other inspection apparatus 100. The recipe verifying server 200 may intercept the inputting recipe RP1 and then automatically check the inputting recipe RP1. If the inputting recipe RP1 is successfully verified, then the inputting recipe RP1 can be uploaded to the other inspection apparatus 100. For example, the recipe verifying server 200 may be a server, a computer or a computer cluster.

[0017] Please refer to FIG. 2, which shows a block diagram of the smart manufacturing controlling system 1000. The recipe verifying server 200 includes a communication unit 210, a storage unit 220, a searching unit 230, a processing unit 240 and a report unit 250. The functions of those elements are described as below. The communication unit 210 is used to transmit and receive data. The communication unit 210 may be, for example, a Wi-Fi module, a network communication module, or a LET communication module.

[0018] The storage unit 220 is used to store data. The storage unit 220 may be, for example, a disk, a memory or a cloud storing center. The processing unit 240 is used to perform a processing procedure or an analyzing procedure. The report unit 250 is used to generate a report. The searching unit 230, the processing unit 240 and/or the report unit 250 may be, for example, a circuit, a chip, a circuit board, a computer program code or a non-transitory computer readable medium.

[0019] Once the inputting recipe RP1 is uploaded from the inspection apparatus 100*, the inputting recipe RP1 is intercepted by the recipe verifying server 200. Only if the inputting recipe RP1 is successfully verified, the inputting recipe RP1 will be uploaded to other inspection apparatuses 100. The operations of those elements are described via a flowchart.

[0020] Please refer to FIGS. 3A, 3B and 4. FIGS. 3A to 3B show a flowchart of a recipe verifying method for the inspection apparatuses 100*, 100.

[0021] FIG. 4 shows a data flow in the recipe verifying method. In step S101, the inputting recipe RP1 is created via the inspection apparatuses 100*. The inputting recipe RP1 has a plurality of inputting parameters Pi, such as scanning range, pixel size, moving step, and etc. The inputting recipe RP1 is created based on the process stage of the wafer WF (shown in FIG. 1). For example, one inspection apparatus may execute the inputting recipe to inspect the die cutting appearance. Or, one inspection apparatus may execute the inputting recipe to inspect any particle.

[0022] Next, in step S102, the inspection apparatus 100* transmits the inputting recipe RP1 to the network.

[0023] Then, in step S103, the communication unit 210 of the recipe verifying server 200 intercepts the inputting recipe RP1. In one embodiment, the communication unit 210 periodically monitors the inspection apparatus 100* to intercept the inputting recipe RP1.

[0024] Then, in step S104, the searching unit 230 of the recipe verifying server 200 searches out a target best known method (BKM) recipe BKM1 from a plurality of candidate BKM recipes BKM0 according to the inputting recipe RP1. The candidate BKM recipes BKM0 are stored in the storage unit 220. The candidate BKM recipes BKM0 are classified based on the process stage, the manufacturing apparatus and the layer. The inputting recipe RP1 may be assigned into one classification based on the process stage, the manufacturing apparatus and the layer. So, in this step, the searching unit 230 can search out the target BKM recipe BKM1 according to the classification of the inputting recipe RP1.

[0025] Afterwards, in step S105, the processing unit 240 obtains a plurality of predetermined limitations LTi according to the target BKM recipe BKM1. The predetermined limitation LTi may be a particular value, a range or a logic combination thereof. For example, “+, −, *, /, ( ), =, >, <, and, or” may be used to described the predetermined limitation LTi.

[0026] Next, in step S106, the processing unit 240 determines whether the inputting parameters Pi of the inputting recipe RP1 meet the predetermined limitations LTi of the target BKM recipe BKM1. If the inputting parameters Pi of the inputting recipe RP1 do not meet the predetermined limitations LTi of the target BKM recipe BKM1, the process proceeds to step S107; if the inputting parameters Pi of the inputting recipe RP1 meet the predetermined limitations LTi of the target BKM recipe BKM1, the process proceeds to step S111.

[0027] In step S107, the report unit 250 generates an error report EP. For example, please refer to FIG. 5, which shows the error report EP according to one example. In the error report EP, the inputting recipes RP11, RP12 and the target BKM recipes BKM11, BKM12 are shown. At least one error is highlighted in the error report EP. For example, a first color, such as green, is used for presenting the inputting parameter P111 which meet the predetermined limitation LT111 and a second color, such as red, is used for presenting the inputting parameter P121 which does not meet the predetermined limitation LT121. The first color is different from the second color. The inputting parameter P121 is highlighted with red color in the error report EP.

[0028] The error report EP may be shown on a display of the recipe verifying server 200. Or, the error report EP may be transmitted to the inspection apparatus 100* and then shown on a display of the inspection apparatus 100*. Or, the error report EP may be transmitted to a mobile device of the user and then shown on a display of the mobile device. The user can clearly see the errors on the error report EP. As shown in FIG. 4, the user can further modify the inputting recipe RP1 according to the error report EP.

[0029] Next, referring to FIG. 5, in step S108, the processing unit 240 determines whether a confirm button B1 is clicked. The error report EP is displayed with the confirm button B1. If the confirm button B1 is clicked, the process proceeds to step S109. Please refer to FIG. 6, which shows a comment window W1. After the confirm button B1 is clicked, the comment window W1 is popped up. The user keys in the user identity number ID, the password WD and the comment CM. The user may write the requesting reason for the permission of the inputting recipe RP1.

[0030] In step S109, the communication unit 210 sends a permission request RQ to a manager. The permission request RQ includes the comment CM and the error report EP. In one case, the inputting recipe RP1 may be created for a new process, so the inputting parameters Pi of this inputting recipe RP1 cannot meet the predetermined limitations LTi of the target BKM recipe BKM1. For this new process, the newly created inputting recipe RP1 can be permitted by the manager.

[0031] Next, in step S110, the processing unit 240 determines whether an authorization message AM is received from the manager. If the authorization message AM is received from the manager, the process proceeds to step S111.

[0032] Then, in step S111, the upload unit 260 uploads the inputting recipe RP1 to the other inspection apparatuses 100.

[0033] Afterwards, in step S112, each of the inspection apparatuses 100 receives the inputting recipe RP1.

[0034] Then, in step S113, each of the inspection apparatuses 100 executes the inputting recipe RP1.

[0035] According to the embodiments described above, once the inputting recipe RP1 is uploaded from the inspection apparatus 100*, the inputting recipe RP1 is intercepted by the recipe verifying server 200. Only if the inputting recipe RP1 is successfully verified, the inputting recipe RP1 will be uploaded to other inspection apparatuses 100. Therefore, any newly created inputting recipe RP1 can be checked automatically for improving the inspection accuracy.

[0036] It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed embodiments. It is intended that the specification and examples be considered as exemplary only, with a true scope of the disclosure being indicated by the following claims and their equivalents.
