Description

Technical Field

[0001] This application relates to the field of semiconductor intelligent manufacturing, and in particular to a method, apparatus and equipment for drawing a Gantt chart of production scheduling in a semiconductor factory. Background Technology

[0002] In semiconductor manufacturing, especially in semiconductor plant scheduling, Gantt charts are a commonly used method for clearly presenting complex production processes, equipment usage, and key time points. For example, a Gantt chart can be used to show the relationship between machines and Lots (25 wafers packed in a die box are called Lots). Specifically, a Gantt chart can show the number of Lots to be processed on a machine, the processing sequence, and the specific processing time.

[0003] Gantt charts are typically drawn based on machine type and time, with a single row representing an individual machine. However, in actual semiconductor manufacturing, even the same machine may require multiple rows to be rendered due to its structural composition. For example, an Etch machine (a key piece of equipment in semiconductor manufacturing used to remove material to form specific patterns) might have scenarios where a Lot is processed sequentially through four cavities or multiple cavities are processed in parallel. Therefore, an Etch machine needs to render its four cavities independently. Consequently, the Gantt chart row objects corresponding to the Etch machine have four levels, and there are relationships between the items at each level. Therefore, existing Gantt charts are not suitable for data differences between different areas within a semiconductor plant, and multiple items are unrelated, making it impossible to view combined relationships. Furthermore, the time granularity of Gantt charts is fixed and cannot be adjusted based on data content; when data exceeds a certain range, the overall data is not visible. Summary of the Invention

[0004] Therefore, in order to overcome the shortcomings of the prior art, the present invention provides a method, apparatus and equipment for drawing Gantt charts of production scheduling in semiconductor factories, which can design different Gantt layer levels and establish correlation relationships for different types of machine processing flows in semiconductor factories; and can adjust the granularity of the page time axis to display more comprehensive information.

[0005] To achieve the above objectives, this invention provides a method for drawing a Gantt chart of production scheduling in a semiconductor factory, comprising: receiving work order schedules corresponding to each processing machine in the scheduling area to be drawn, and determining the time granularity of the time axis of the Gantt chart based on the work order schedules; constructing a data structure hierarchy corresponding to each processing machine based on the business scenario of the processing machine to display the relationship between the business scenarios; receiving a real-time Gantt chart rendered and fed back by the server, wherein the server receives interface data corresponding to each processing machine, calculates the interface data, and draws task bars that make up the business scenario according to the time granularity through each Gantt chart component to obtain a real-time Gantt chart corresponding to the work order schedule; displaying the real-time Gantt chart so that the task bars can be dragged and modified, and outputting the real-time Gantt chart after drag-and-drop verification.

[0006] In one embodiment, determining the time granularity of the Gantt chart's time axis based on the work order schedule includes: determining the processing time corresponding to each work order task based on the work order schedule; configuring the initial time granularity based on the processing time, the configuration being determined according to the business characteristics of the scheduling area; displaying the time axis and obtaining the input adjustment granularity, and modifying the time axis based on the adjustment granularity to adapt to global or detailed data viewing needs.

[0008] In one embodiment, the server uses an independent thread to handle the logic of each work order task, and a main thread to handle the logic between task modules.

[0009] In one embodiment, the step of constructing a data structure hierarchy corresponding to the processing machine based on the business scenario of the processing machine to display the association between the business scenarios includes: obtaining the execution hierarchy between the processing machine and the work order task based on the business scenario of the processing machine, and obtaining the mapping relationship between the processing machine and the work order task; performing dependency hierarchy analysis on the work order task based on the execution hierarchy and the mapping relationship, and generating Gantt chart row objects in the data structure hierarchy.

[0010] In one embodiment, displaying a real-time Gantt chart includes: organizing work order data from all business scenarios into a list or array; distributing the work order data to multiple pages using pagination logic; generating a Gantt chart for each page using a chart library; and adding navigation buttons to facilitate user switching between different pages.

[0011] In one embodiment, displaying a real-time Gantt chart to allow dragging and modifying the task bar, and outputting a drag-verified real-time Gantt chart, includes: obtaining the starting and ending horizontal coordinates of the Gantt chart row object selected by the user being dragged, and obtaining the affected associated row objects; recalculating the start time positions of the Gantt chart row objects and the associated row objects based on the starting and ending horizontal coordinates; performing business logic verification on the calculated start time positions; and outputting and displaying the drag-verified real-time Gantt chart.

[0027] This application provides a method for drawing a Gantt chart of production scheduling in a semiconductor factory. It can be applied to a server or a terminal. The terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable smart devices. The server can be a standalone server or a server cluster composed of multiple servers. Figure 1 As shown, taking the application of this method to a terminal as an example, the steps include:

[0028] Step 101: Receive the work order schedules corresponding to each processing machine in the scheduling area to be drawn, and determine the time granularity of the time axis of the Gantt chart based on the work order schedules.

[0029] A Gantt chart row object is a data packet with a Gantt chart-recognizable data structure, including row numbers, task start time, end time, and image tile objects. For example... Figure 2 As shown, the task list on the left side of the Gantt chart contains different times, and in the Gantt chart display area on the right, different row numbers represent different processing machines. Row numbers can be represented by strings or numbers. Figure 2The row numbers, such as BARC_01, BARC_02, and BARC_03, correspond to different processing machines, with different shades of gray representing different work order tasks. A Gantt chart row object records not only the row number corresponding to a processing machine and a work order task, but also the earliest start time, the latest end time, and the corresponding image block object. The image block object records the vertical, starting, and ending horizontal coordinates of the image block, indicating its position within the Gantt chart. These coordinates allow the drawing of the image block corresponding to the work order task, and different image blocks form the Gantt chart. Since a task may be divided into multiple time segments, each time segment corresponds to an image block, resulting in multiple image blocks within a single Gantt chart row object. The Gantt chart row object can also include basic data about the work order task, such as task number, quantity, product number, and production department. This data can be used to construct and display a task list.

[0030] Work order scheduling is a mapping table between work order tasks and processing machines. It not only rationally allocates work order tasks to different processing machines, but also stores the start and end times of each work order task.

[0031] A scheduling area refers to a designated area within a factory that contains at least one processing machine with work orders already scheduled for execution or already in operation. Drawing a Gantt chart of this scheduling area helps production managers visually understand the allocation of work orders, timelines, and resource utilization.

[0032] The terminal receives the work order schedules corresponding to each processing machine within the scheduling area to be plotted, and determines the time granularity of the Gantt chart's time axis based on the work order schedules. The processing time for a Lot varies depending on the processing machine. For example, processing a batch in the furnace tube area takes 6-8 hours, while photolithography processing a Lot takes less than 30 minutes. Therefore, the time granularity of the Gantt chart's time axis needs to be adjusted according to the characteristics of the work order schedules in different areas to avoid situations where one area is displayed completely while another only shows a portion.

[0033] Step 102: Construct a data structure hierarchy corresponding to the processing machine based on the business scenario of the processing machine to show the relationship between the business scenarios.

[0034] The terminal constructs a data structure hierarchy corresponding to the processing machine based on the processing machine's business scenario to display the relationships between these scenarios. The terminal constructs different structural hierarchies based on the processing machine's business scenario. For example, the terminal recognizes multiple business scenarios in the Etch machine, such as "the Lot is processed sequentially through four cavities or multiple cavities are processed in parallel." Therefore, the image block object corresponding to the Etch machine can be first divided into a hierarchy of four cavities. In parallel processing scenarios, when the same Lot is split into multiple sub-Lots (slicing strategy), each part is displayed as the same Lot. Specifically, when a color block is selected, multiple associated color blocks are simultaneously selected, displaying the relationship.

[0035] The Gantt chart displays various states of a Lot, such as processing and production preparation, and various states of a machine, such as Down (machine unavailable due to malfunction), Monitor (machine production progress), and Season (machine switching processing environment). In the Etch machine, the Down state of the machine will be transformed into the Down state of the cavity. During this process, multiple sub-projects and parent projects are also simultaneously linked.

[0036] Step 103: Receive the real-time Gantt chart rendered by the server. The server receives the interface data corresponding to each processing machine, calculates the interface data, and uses each Gantt chart component to draw task bars for the business scenario according to the time granularity, thus obtaining a real-time Gantt chart corresponding to the work order schedule.

[0037] The terminal receives the real-time Gantt chart rendered and fed back by the server. The server receives the interface data corresponding to each processing machine, calculates the interface data, and uses each Gantt chart component to draw task bars for the business scenario according to the time granularity, thus obtaining a real-time Gantt chart corresponding to the work order schedule.

[0038] By placing the data conversion process on the server side during rendering, the potential memory bottlenecks that may occur when the terminal processes data are avoided, as well as the risk of memory overflow on the terminal.

[0039] Step 104: Display the real-time Gantt chart so that the task bar can be dragged and modified, and output the real-time Gantt chart after drag-and-drop verification.

[0040] The terminal displays a real-time Gantt chart, allowing users to drag and drop tasks to modify them, and outputs a real-time Gantt chart after drag-and-drop verification. After generating the Gantt chart for the work order schedule, the terminal also generates a Gantt chart API and publishes it. After publication, the terminal receives the API call request and, based on the request, displays the Gantt chart and its plotting data through the API, enabling users to view the Gantt chart or drag and drop specific blocks within the real-time Gantt chart to modify and regenerate the chart.

[0041] After displaying a real-time Gantt chart on the terminal, business personnel may find that the sorting of certain lots on the processing machine does not meet actual business needs and require increasing the priority of certain lots. This necessitates manual modification of the Gantt chart results. The terminal displays a real-time Gantt chart, allowing business personnel to drag and drop an image object block of a specific lot on the timeline. After the movement, the terminal re-acquires the start time position and recalculates the start and end times of subsequent activities. The terminal validates the dragged Gantt chart to determine if it conforms to business logic. Business logic could include whether the start time of the dragged lot exceeds its arrival time at the machine. When the drag is deemed to conform to business logic, the validated real-time Gantt chart is output.

[0042] The above method constructs a data structure hierarchy corresponding to different types of processing machines within a semiconductor factory, designs different Gantt chart hierarchy levels, and establishes relationships to display the connections between business scenarios. It can also determine the time granularity of the Gantt chart's time axis based on work order scheduling, thereby adjusting the page's time axis granularity and displaying more comprehensive information. Furthermore, it displays a real-time Gantt chart, allowing for drag-and-drop modification of the task bar, and outputs a real-time Gantt chart after drag-and-drop verification, enabling rapid adjustments.

[0043] In one embodiment, determining the time granularity of the Gantt chart's time axis based on the work order schedule includes: determining the processing time corresponding to each work order task based on the work order schedule; configuring the initial time granularity based on the processing time, the configuration being determined according to the business characteristics of the scheduling area; displaying the time axis and obtaining the input adjustment granularity, and modifying the time axis based on the adjustment granularity to adapt to global or detailed data viewing needs.

[0044] The terminal determines the processing time for each work order task based on the work order schedule, and then selects a time range based on the processing time. Based on the selected time range, the terminal generates a Gantt chart time axis according to preset mapping rules. The preset mapping rules include determining the time range and actual pixel values ​​mapped to each unit length of the time axis based on different time modes.

[0045] The terminal configures the initial time granularity based on the processing time, and the configuration is determined by the business characteristics of the scheduling area. The terminal can obtain a pre-stored configuration table, which configures the initial time granularity for each processing machine in the scheduling area. For example, the selectable granularity of the initial time granularity is 0.5, 1, 2, 4, 6, 8, 10, 12, 24, 48, and 72, with the unit being hours (h).

[0046] When the processing machine is not found in the configuration table by the terminal, the terminal selects a specific time granularity, such as 0.5 hours.

[0047] The terminal displays a timeline and obtains the input adjustment granularity. It then modifies the timeline based on this adjustment granularity to suit both global and detailed data viewing needs. Alternatively, the terminal displays a timeline generated based on the initial time granularity, then obtains the adjustment granularity input by the business personnel, and modifies the timeline accordingly to adapt to both global and detailed data viewing needs.

[0048] The above method first automatically adjusts the granularity of the timeline based on the work order tasks, and then makes a second adjustment based on the display needs of the business personnel, ensuring that all work order tasks can be displayed completely in the display area even under specific viewing requirements.

[0049] In one embodiment, the calculation interface data is used to draw task bars that make up the business scenario according to the time granularity of each Gantt chart component to obtain a real-time Gantt chart corresponding to the work order schedule. The steps include: calculating the start time and end time of each work order task on the time scale table according to the interface data and the work order schedule; drawing the work order tasks with scalable vector graphics and binding the work order tasks to preset slots to obtain task blocks; and generating a real-time Gantt chart corresponding to the work order schedule based on the time scale table and task blocks.

[0050] The server calculates the start and end times of each work order task on the time scale based on the interface data and work order scheduling. The server determines the start and end times of the current work order on the time scale based on the feedback from the interface data and the work order scheduling. The interface data is the information provided by the processing machine to the server regarding whether the current work order task is progressing smoothly.

[0051] After the server determines the start and end times of the target task, it can draw the shape of the target task using scalable vector graphics and bind the drawn shape to preset slots to obtain the task blocks corresponding to the Gantt chart. When generating slots, the server can determine the pre-set target slot template in the database based on the slot rendering data sent by the user. Then, the terminal renders the target slot template according to the slot rendering data. It should be noted that a slot template is a means of rendering and displaying data using pre-made templates. Its main function is to format content. For example, given slot templates A and B, for the same data D, it can be displayed as a loop four times with red text in A, while it can be displayed as multiple lines in B. That is, different slot templates correspond to different layout methods.

[0052] The server generates a real-time Gantt chart corresponding to the work order schedule based on a time scale and task modules. The Gantt chart can be... Figure 2 A Gantt chart containing multiple work order tasks can also be Figure 3 A Gantt chart corresponding to multiple levels of the processing machine.

[0053] like Figure 3As shown, the server divides the business scenario of Lot being processed sequentially through four cavities into four cavities corresponding to the Etch machine. In the parallel processing scenario, when the same Lot is split into multiple sub-Lots (sharding strategy), each part is displayed as the same Lot. Specifically, when a certain color block is selected, multiple associated color blocks are selected simultaneously, showing the relationship.

[0054] In the above method, the server obtains each Gantt chart row object from the Gantt chart based on the interface data and work order scheduling, and sends the Gantt chart row objects to the terminal, thereby avoiding the memory bottleneck that may exist in the terminal's data processing and avoiding the risk of memory overflow.

[0055] In one embodiment, the server uses independent threads to handle the logic of each work order task, and a main thread to handle the logic between task modules. The thread pool contains the main thread and independent threads. The server can use the thread pool to process multiple work order tasks in parallel to obtain Gantt chart row objects in the Gantt chart.

[0056] In one embodiment, a data structure hierarchy corresponding to the processing machine is constructed based on the business scenario of the processing machine to display the relationship between business scenarios. This includes: obtaining the execution hierarchy between the processing machine and the work order task based on the business scenario of the processing machine, and obtaining the mapping relationship between the processing machine and the work order task; performing dependency hierarchy analysis on the work order task based on the execution hierarchy and mapping relationship, and generating Gantt chart objects in the data structure hierarchy.

[0057] The terminal obtains the execution level between the processing machine and the work order task based on the business scenario of the processing machine, and obtains the mapping relationship between the processing machine and the work order task. The terminal uses each cavity in the processing machine as the smallest unit on the vertical axis, distinguishes the execution level of the Gantt chart object corresponding to each work order task on the vertical axis according to different processing machines, and obtains the mapping relationship between the processing machine and the work order task.

[0058] Based on the execution hierarchy and mapping relationships, the terminal performs dependency hierarchy analysis on work order tasks, generating Gantt chart objects at the data structure level. The terminal determines the work sequence between different lots and different work order tasks according to the business scenario of the processing machine, and performs dependency hierarchy analysis on work order tasks based on the execution hierarchy and mapping relationships, generating Gantt chart objects at the data structure level.

[0059] In one embodiment, displaying a real-time Gantt chart includes: organizing work order data from all business scenarios into a list or array; distributing the work order data to multiple pages using pagination logic; generating a Gantt chart for each page using a chart library; and adding navigation buttons to facilitate user switching between different pages.

[0060] In one embodiment, displaying a real-time Gantt chart to allow dragging and modifying of the task bar, and outputting a drag-verified real-time Gantt chart, includes: obtaining the starting and ending horizontal coordinates of the Gantt chart row object selected by the user being dragged, and obtaining the affected related row objects; recalculating the start time positions of the Gantt chart row objects and related row objects based on the starting and ending horizontal coordinates; performing business logic verification on the calculated start time positions, and outputting and displaying the drag-verified real-time Gantt chart.

[0061] The terminal obtains the starting and ending horizontal coordinates of the Gantt chart row object selected by the user and the affected related row objects. After adjusting the Gantt chart, the terminal can determine the axis scale information corresponding to the adjusted target Gantt chart, and then determine the time information corresponding to the axis scale information. It can then adjust the time information of the work order tasks corresponding to the Gantt chart row objects to modify the start and end times of the work order tasks. This enables the simultaneous display of the start and end times of the dragged bar chart at both ends, achieving simpler drag-and-drop interaction.

[0062] The terminal recalculates the start time and position of the Gantt chart row objects and related row objects based on the start and end horizontal coordinates. During the generation of the real-time Gantt chart, the terminal parses the work order data from the work order schedule and binds the Gantt chart row object attribute interaction events to each work order task according to the work sequence of each work order task. This generates drag-and-drop rules to limit the movement range of Gantt chart row objects within each work order and prohibits dragging across production lines.

[0063] The terminal performs business logic verification on the calculated start time position, outputs and displays a real-time Gantt chart after drag-and-drop verification. The business logic may include time-based judgment logic such as whether the start time of Lot processing after dragging exceeds its arrival time at the machine, or whether the end time of Lot processing exceeds its departure time from the machine.

[0064] The above method allows for manual drag-and-drop modification of Gantt chart results, thereby meeting different business needs.

[0065] In one embodiment, such as Figure 4 As shown, a semiconductor factory production scheduling Gantt chart drawing device is provided. The device includes a granular configuration module 401, a hierarchical construction module 402, a rendering module 403, and a display module 404.

[0066] The granularity configuration module 401 is used to receive the work order schedules corresponding to each processing machine in the scheduling area to be drawn, and to determine the time granularity of the time axis of the Gantt chart based on the work order schedules.

[0067] The hierarchy construction module 402 is used to construct a data structure hierarchy corresponding to the processing machine based on the business scenario of the processing machine, so as to show the relationship between the business scenarios.

[0068] The rendering module 403 is used to receive the real-time Gantt chart from the server-side rendering feedback. The server receives the interface data corresponding to each processing machine, calculates the interface data, and uses each Gantt chart component to draw task bars for the business scenario according to the time granularity, thus obtaining a real-time Gantt chart corresponding to the work order schedule.

[0069] The display module 404 is used to display a real-time Gantt chart so that the task bar can be dragged and modified, and the real-time Gantt chart after drag-and-drop verification is output.

[0080] The analysis unit is used to perform dependency hierarchy analysis on work order tasks based on execution hierarchy and mapping relationships, and generate Gantt chart row objects at the data structure level.

[0081] In one embodiment, the display module includes:
