[0022] A control chart configuration method, device, electronic device and storage medium provided in an embodiment of the present application can store candidate control chart types and candidate control parameter items in two data tables respectively. When a new control chart type is added, it is only necessary to add data to the data table. There is no need to store the candidate control chart type and the candidate control parameter items in one data table at the same time as in the prior art, which results in the need to modify the data table structure each time a new control chart type is added. Compared with the control chart configuration method in the prior art, the problem of long development time and high development cost when adding a new control chart type is solved.

[0023] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, preferred embodiments are specifically cited below and described in detail with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope.

[0028] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0029] It is worth noting that before the present application was proposed, the control chart was a chart with control limits used to analyze and determine whether the process was in a stable state. The control chart of the Statistical Process Control (SPC) system can perform parameter test data collection, rule determination, and control actions on process quality, and is an effective means of implementing quality control. At present, most SPC software systems usually only provide a few fixed control chart types, such as: Xbar, Sigma, Range, MR. However, with the continuous improvement of quality control requirements, there are more and more demands for control chart types. When users need to configure new control chart types, they need to invest R&D funds and manpower for additional customization. For example: in MaskShop process production, it is necessary to expand custom Chart types (control chart types) such as MTT, RTT, and SIG3TT. In the prior art, the control chart type and the control parameter items corresponding to each control chart type are stored in a table, and each control parameter item under each control chart type corresponds to a field. For example, the fields stored in the data table are the average value control upper line, the average value control lower line, the average value specification upper line, the average value specification lower line, the range control upper line, the range control lower line, the range specification upper line, the range specification lower line, etc. When a new control chart type is added, it is necessary to modify the data structure, add a new field to the data table, or insert a new field in the middle of multiple control parameter items. When a new field is inserted in the middle of multiple control parameter items, the order of the control parameter items displayed in the graphical user interface will also change. However, the cost of customizing a new control chart type is high and the development time is long, which cannot meet the growing user demand for control chart customization.

[0030] Based on this, an embodiment of the present application provides a control diagram configuration method to reduce the development time and development cost when adding a new control diagram type.

[0031] See also Figure 1 , Figure 1This is a flow chart of a control diagram configuration method provided in an embodiment of the present application. Figure 1 As shown, the control diagram configuration method provided in the embodiment of the present application includes:

[0032] Step S101, in response to a configuration information creation instruction for a target parameter, respectively obtaining candidate control chart types and candidate control parameter items corresponding to each control chart type from two control chart configuration tables;

[0033] Step S102, providing candidate control diagram types and candidate control parameter items corresponding to each control diagram type in a graphical user interface;

[0034] Step S103 , in response to a configuration information saving instruction for a target parameter, storing control diagram configuration information of the target parameter corresponding to the configuration information saving instruction.

[0035] The control chart configuration method provided in the embodiment of the present application can store candidate control chart types and candidate control parameter items in two data tables respectively. When a new control chart type is added, it is only necessary to add data to the data table. There is no need to store the candidate control chart type and the candidate control parameter items in one data table at the same time as in the prior art, which results in the need to modify the data table structure each time a new control chart type is added. This solves the problem of long development time and high development cost when adding a new control chart type.

[0036] To facilitate understanding of this embodiment, the above exemplary steps provided in the embodiment of the present application are described below by taking the control chart configuration method applied to a statistical process control system as an example.

[0037] In step S101, in response to a configuration information creation instruction for a target parameter, candidate control chart types and candidate control parameter items corresponding to each control chart type are respectively obtained from two control chart configuration tables.

[0038] In this step, the control chart type may refer to a Chart type in an SPC (statistical process control) system, and the control chart types include but are not limited to: Xbar, Sigma, Range, MR, MTT, RTT, and SIG3TT.

[0039] The two control chart configuration tables include the control chart type table and the data control table.

[0040] The following describes the control chart type table with reference to Table 1.

[0041] Chart_seq Chart_name 1 MTT 2 RTT 3 SIGMA

[0042] Table 1 is a control chart type table. As shown in Table 1, the control chart type table is used to record candidate control chart types. The control chart type table includes two fields: control chart type identifier Chaart_seq and control chart type name Chart_name. For example, if three control chart types MR, MTT, and RTT are filled in the control chart type table, then MR, MTT, and RTT are candidate control chart types.

[0043] The following refers to Table 2 to introduce the control chart type table.

[0044] Chart_seq Chart_name USL LSL CL UCL LCL 1 MTT 0.8 -0.8 0.72 -0.72 2 RTT 0.8 -0.8 0.72 -0.72 3 SIGMA 0.8 0.72

[0045] Table 2 is a data control table. As shown in Table 2, the data control table is used to record the control parameter items of each candidate control chart type and the specific values ​​of the control parameter items. The control parameter items corresponding to each candidate control chart type are called candidate control parameter items. The data control table includes multiple fields: Chart_seq (control chart type identifier), Chart_name (control chart type name), UCL (upper control line), LCL (lower control line), CL (center line), USL (upper specification line), and LSL (lower specification line).

[0046] The candidate control chart type may refer to the control chart type configured in the control chart configuration table. The candidate control parameter item may refer to the control parameter item configured in the data control table.

[0047] Exemplarily, when only control parameter items corresponding to two control graph types, MR and MTT, are configured in the data control table, five control parameter items corresponding to MR and five control parameter items corresponding to MTT are candidate control parameter items.

[0048] In an embodiment of the present application, in the mask production process (MaskShop process) of semiconductor devices, in order to better control and monitor the production process, it is necessary to use the SPC system to collect the data generated in the production process, and generate corresponding control charts based on the collected data. Different control chart types can reflect the actual situation of the production process from different dimensions. To this end, the control chart type table and the data control table can be configured in advance before the configuration information creation instruction is issued. For example, seven control chart types can be configured in the control chart type table, namely: Xbar, Sigma, Range, MR, MTT, RTT, SIG3TT, and the control parameter items corresponding to each of the above seven control chart types are configured in the data control table, and the control chart type identifiers of the seven control chart types are 1 to 7. Then, all candidate control chart types are obtained from the control chart type table, and the candidate control parameter items corresponding to each control chart type are obtained from the data control table. In this way, a total of seven candidate control chart types and five candidate control parameter items corresponding to each candidate control chart type are obtained.

[0049] In step S102, candidate control diagram types and candidate control parameter items corresponding to each control diagram type are provided in a graphical user interface.

[0050] In this step, the statistical process control system includes a graphical user interface, and the content displayed in the graphical user interface includes three parts, namely, SPEC information, candidate control chart types and candidate control parameter items.

[0051] Among them, SPEC information may refer to the control chart configuration information of all parameters recorded under the current project, for example: SPEC information under the process flow of screen detection. SPEC information includes multiple SPEC information, each SPEC information is a collection of all control chart configuration information recording a parameter, for example: a SPEC information may be all control chart configuration information under the parameter of metal layer thickness. Among them, the current project may refer to the inspection project under the current production process or the current process flow, for example: to inspect the mask production process, then the current project is the mask inspection project, and the mask inspection project involves multiple parameters, then the multiple SPEC information corresponding to these multiple parameters is all the control chart configuration information under the current project.

[0052] The candidate control chart types include multiple candidate control chart types. Taking the above example, seven candidate control chart types will be displayed in the candidate control chart type part.

[0053] The candidate control parameter items include the names of multiple candidate control parameter items and a parameter value box for each candidate control parameter item. Taking the above example, a total of thirty-five candidate parameter items corresponding to seven candidate control diagram types will be displayed in the candidate control parameter item part.

[0054] In one example, in response to a selection instruction for a candidate control diagram type, a target control diagram type is determined; in response to a selection and configuration instruction for a candidate control parameter item, a target control parameter item and a parameter value of the target control parameter item under the target control diagram type are determined.

[0055] For example: In the graphical user interface of the SPC system, a check box is set in front of each candidate control chart type. When the user wants to obtain a control chart with target parameters under MTT and RTT, the user can check the check boxes before MTT and RTT in the graphical user interface to generate a selection instruction for the candidate control chart type to select MTT and RTT as the target control chart types.

[0056] At the same time, the user can also enter a specific value in the parameter value box of the graphical user interface to generate a selection and configuration instruction to determine the parameter value of the target control parameter item, wherein the target control parameter item includes a first control parameter representing the upper and lower control lines, and / or a second control parameter representing the upper and lower specification lines, and / or a third control parameter representing the center line. The first control parameter includes the upper control line and the lower control line, the second control parameter includes the upper specification line and the lower specification line, and the third control parameter includes the center line. For example: the user can enter a specific value in the parameter value box corresponding to the first control parameter of MTT to determine the value of the upper specification line and the lower specification line corresponding to MTT.

[0057] In one example, when it is necessary to add, delete or modify a candidate control chart type in the SPC system, it is only necessary to modify the control chart type table. At this time, in response to a type modification instruction for a candidate control chart type in the control chart type table, the candidate control chart types provided in the graphical user interface are adjusted.

[0058] For example, if the user wants to add a new candidate control chart type X / Y-DELTA, he only needs to add a new row in the control chart type table, set the control chart type identifier in the row to 8, and the control chart type name is X / Y-DELTA. Then, enter the type modification command or click the interface refresh button, and eight candidate control chart types will be displayed in the graphical user interface, including the newly added X / Y-DELTA. Similarly, when a candidate control chart type is deleted from the seven candidate control chart types in the control chart type table, six candidate control chart types will be displayed in the graphical user interface.

[0059] In one example, when it is necessary to add, delete or modify candidate control parameter items in the SPC system, it is only necessary to modify the data control table. At this time, in response to the parameter item modification instruction for the candidate control chart type in the data control table, the candidate control parameter items provided in the graphical user interface are adjusted.

[0060] For example: after adding the X / Y-DELTA candidate control chart type, you need to add a new candidate control parameter item corresponding to X / Y-DELTA. You only need to add a new row in the data control table, set the control chart type identifier in this row to 8, and name the control chart type as X / Y-DELTA. Then, enter the parameter item modification instruction, save, or click the interface refresh button, and the five candidate control parameter items corresponding to X / Y-DELTA and the parameter value box after each candidate control parameter item will be displayed in the graphical user interface. Similarly, when a candidate control chart type is deleted from the seven candidate control chart types in the data control table, the candidate control parameter items corresponding to each of the six candidate control chart types will be displayed in the graphical user interface.

[0061] In step S103, in response to a configuration information saving instruction for a target parameter, control diagram configuration information of the target parameter corresponding to the configuration information saving instruction is stored.

[0062] In this step, the configuration information saving instruction may refer to an instruction to save the configuration information. As an example, the configuration information saving instruction may be issued via a save configuration button in a graphical user interface.

[0063] In an embodiment of the present application, after receiving the configuration information saving instruction, the control chart configuration information of the target parameter under the target control chart type is generated and saved according to the mapping relationship between the target parameter, the target control chart type and the parameter value, that is, the parameter values ​​of different control parameter items under each target control chart type are saved according to the data control table, for example: the saved data includes SPEC ID CD_GA, the name of the target control chart type is MTT, the parameter value of UCL corresponding to MTT is 0.72, and the parameter value of LCL corresponding to MTT is -0.72. Among them, SPEC ID is the target parameter identifier. Then, a connection is established between the control chart configuration information corresponding to all parameters under the current project to obtain and save the control chart configuration information of all target parameters under the current project.

[0064] The following refers to Table 3 to introduce all the control chart configuration information saved in the current project.

[0065] FACTORY SPEC_ID MASK CD_GA MASK CD MASK C_CD

[0066] Table 3 is all the control chart configuration information under the current project. As shown in Table 3, all SPEC_IDs under the MASK project are recorded. Each SPEC_ID corresponds to all the control chart configuration information of a parameter. In this way, all the control chart configuration information under the MASK project can be obtained.

[0067] In this way, after determining the control chart configuration information of the target parameter, when generating the control chart of the target parameter, the control chart configuration information corresponding to the target parameter can be obtained, and according to the name of the control chart type in the control chart configuration information, the specific calculation formula corresponding to each control chart type can be obtained from the background, and then the value under each control chart type is determined according to the calculation formula, so as to generate the control chart of the target parameter by using the value and the parameter value of the target control parameter item.

[0068] Based on this, the present application can flexibly modify the control chart configuration information by adding, deleting or modifying row data in the control chart type table and the data control table, without modifying the data table structure (adding or deleting fields) and program code, thereby reducing development time and development costs.
