The present disclosure relates to the field of panel manufacturing technologies, and in particular, to a substrate processing method.
The equipment of a panel factory are divided into a process machine table and a measuring machine table. The process machine table is the table that a glass substrate will certainly run through, and the measuring machine table is the table that the glass substrate is not necessarily required to run through. Taking a thin film transistor (TFT) manufacturing process as an example, the process machine table adopted relates to three main process flows: a thin film process, a lithography process, and an etching process, all of which are needed to be carried out for five cycles, and the sequence of the processes cannot be wrong. In a Manufacturing Execution System (MES), a process flag is used for controlling. Specifically, 15 bits (corresponding to three processes*5 cycles) are used for a process flag, an initial value of which is 000000000000000, and a corresponding bit is set to be 1 after one main process flow, for example, the process flag is changed to be 100000000000000 after the first thin film process flow. If reworking is carried out, the corresponding bit of the process flag will be set to be 0. Therefore, as for the current method, if the number of cycles of the process is increased, the bit number of the process flag is increased, and in consideration of reworking as well, the control logic of on/off of the process flag is very difficult for coding. Moreover, due to the fact that a hard code manner is adopted, if the process needs to be modified in the future, the program source codes need also to be modified, thus the method is very inconvenient.
An embodiment of the present disclosure is to provide a substrate processing method, so that the process flag control logic is optimized, and an effective control of process flows of a substrate is achieved.

To illustrate the technical solutions according to the embodiments of the present disclosure more clearly, the accompanying drawings for describing the embodiments are introduced briefly in the following. Apparently, the accompanying drawings in the following description are only about some embodiments of the present disclosure, and persons of ordinary skill in the art can derive other drawings from the accompanying drawings without creative efforts.
The technical solutions of the embodiments of the present disclosure will be clearly and completely described in the following with reference to the accompanying drawings. It is obvious that the embodiments to be described are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by persons skilled in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
The substrate processing method provided by the embodiment of the disclosure adopts a new process flag control logic. Specifically, a system screen and the logic relate to the process flag control logic of the embodiment are shown in
In addition, the operator may also select a certain operation site at operation site bar in the operation list setting interface shown in
It is noted that the main process flow operation list is shown in
Referring to
S201: loading an operation list of substrate;
S203: loading a substrate onto a production line;
S205: when the substrate flows to an operation site on the production line, the operation site is inquired at the operation site bar of the operation list, and judging whether the operation site is provided with an inspection site;
S207: if the operation site is provided with an inspection site at the inspection site bar, verifying whether a current operation flag of the substrate matches the inspection site;
S209: if the current operation flag of the substrate matches the inspection site, processing the substrate at the operation site.
In details, the operation list loaded in S201 is, for example, a main process flow (MAIN) operation list loaded by an MES system, and the operation list includes an operation sequence number bar, an operation site bar, an inspection site bar and an operation flag record enabling bar, in order to increase user-friendliness and the expandability of the interface, other bars could be further included. More specifically, in
In S203, the substrate is loaded onto a production line, such as shown in
As described above, in S205, when the substrate flows into a certain operation site on the production line, such as the operation site A1200 after the operation site A1100 shown in
In S207, continues to take the operation site A1200 as an example, the operation site A1200 is provided with an inspection site A1100 at the inspection site bar; the system will continue to verify whether the current operation flag of the substrate matches the inspection site A1100. Wherein the current operation flag of the substrate is obtained by: obtaining a S/N number set on the substrate by a scanner provided on the operation site A1200, and then inquiring an operation flag corresponding to the S/N number in the system database according to the S/N number. The operation flag herein is typically represented by operation sites (e.g., an operation site identification number). If the S207 verifies that the current operation flag of the substrate matches the inspection site A1100, it indicates that the verification is successful, then executing S209; otherwise, if not matching, it indicates that the verification fails, and a message is returned to indicate causes of the failure, the operation site A1200 will not process the substrate later, in other words, the operation site A1200 will not allow the substrate to enter.
In S209, if the current operation flag of the substrate matches the inspection site A1100, which indicates that the substrate has gone through operation site A1100, that is, the verification is successful, so that the substrate is processed by the process equipment of the operation site A1200. The glass substrate for the display panel is taken as an example, the processing is, for example, a thin film process, a lithography process or an etching process.
In addition, the substrate processing method of the embodiment may further include the following steps: if the operation site is set to be in an enabling state at the operation flag record enabling bar, after the substrate is processed at the operation site completely, the operation flag of the substrate is recorded to be the operation site to update the current operation flag of the substrate. Taking the operation site A1100 as an example, it is set to be in an enabling state (Y) at the operation flag record enabling bar, after the substrate is processed at the operation site A1100 completely, an MES system records the operation flag of the substrate (represented by the S/N number) to be operation site A1100, so that a verification of sites may be carried out subsequently.
Further, the substrate processing method according to the embodiment may further include the following steps before S210: obtaining an operation list setting interface (such as shown in
