Description

Technical Field

[0001] The present invention relates to the field of semiconductor packaging test production control technology, and in particular to a manufacturing data acquisition system for semiconductor chip packaging test. Background Art

[0002] Semiconductor chip packaging and testing involves quality management in many aspects, including personnel, materials, objects, methods, and environment. Key indicators need to be collected in each link of the management process. There are many types of indicators, and the inspection and verification of each indicator parameter item are related to the quality control of production. The degree of automation of information collection is directly related to the production efficiency of employees. The system integration capability (horizontally or vertically) is strongly related to the process control, real-time alarm, data governance and utilization of production, which ultimately affects the production decision-making power and product delivery capabilities.

[0003] The existing data collection system has been able to digitize paper data collection, realize paperless production line information collection, and save a certain amount of cost. The data collection system adopts a typical MVC (Model-View-Controller) model in structure, with the front-end web page as the information collection end, and the back-end service processing requests and access to the database. In principle, the system is divided into equipment module, department module, role module, and collection module. The system administrator can assign roles and departments to users according to the actual production line. Collection sheet designers can create collection sheets according to the process flow, define collection items, and classify and group collection sheets. The system is embedded with Microsoft Excel functions, and collection sheet designers can independently design collection sheets and collection sheet styles. Operators need to log in to the web page to determine the location of the collection sheet according to the product and process flow, manually create a collection information table (also called a collection table) based on the collection sheet, manually enter the collected information and submit it for saving, etc.

[0004] Although the existing data collection system has achieved the transition from paper-based collection to paperless collection, saving a certain amount of material costs, there are still many problems:

[0005] 1. Lack of automated creation of collection orders and automatic entry of collection order information. During the complex production process, operators need to log in to the system at different production nodes (such as product verification, switching, loading and unloading), manually create collection orders corresponding to the production nodes, and manually enter the collection item information. This process lacks automation, resulting in many wrong orders and low collection efficiency, which affects output;

[0006] 2. The format of the collection form depends on the subjective experience of the collection form designer (such as process engineers). There are various collection form formats, which results in high learning costs and low efficiency for operators to identify and operate the collection form.

[0007] 3. There is no role control for multi-role collection tasks. The information collection list has many details, involving multiple departments and multiple roles to cooperate in the collection operation. There is no authority control in the collection process. This method is difficult to ensure the reliability and security of information;

[0008] 4. The existing data collection system is a typical "information island". Data can only be shared within the department. There is no information bridge with any system, and multi-department data sharing cannot be achieved. Summary of the invention

[0009] The present invention provides a manufacturing data acquisition system, which is used to solve at least some of the technical problems existing in the existing data acquisition system. The technical solution is as follows:

[0043] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described in detail in conjunction with the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present invention. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for clarity and brevity, the description of known functions and structures is omitted.

[0044] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0045] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0046] The embodiment of the present invention provides a manufacturing data collection (MDC) system. The system is based on the nature of the collection unit and the actual production line, and uses the existing software and hardware of the factory to achieve the design, creation, input, and verification of the collection unit at the lowest cost, thereby simplifying and automating the process, effectively improving the work efficiency of users and operators, and reducing time and labor costs. The system can also realize the integration, processing, storage, and retrieval of data flows of various process flows, greatly improving the quality of information and realizing multi-dimensional presentation of data. In addition, the system is integrated with the CIM system to break the "information island", and can realize automatic verification of key collection items, timely control problem items in the production process, and effectively improve quality management.

[0047] The manufacturing data acquisition system provided by the embodiment of the present invention adopts a front-end and back-end separation architecture in the technical solution, which makes the system more maintainable and fast iterative. The system architecture is reconstructed to support high concurrency, high availability, and high scalability. At the same time, the system takes into account both system performance and operation and maintenance efficiency, and realizes system load balancing and high availability under high concurrency through Nginx technology, and realizes micro-sustainable deployment by using virtualization technology and Docker (container) technology, which greatly reduces the system operation and maintenance workload and the cost of fast iteration, effectively realizing the cost reduction and efficiency improvement of the enterprise and improving the quality and ability of product delivery.

[0048] like Figure 1As shown, the manufacturing data acquisition system (also called MDC system) provided by the embodiment of the present invention includes:

[0049] The user module 100 is used to implement user management and user group management. The user management includes user legitimacy verification. The user group management includes classifying and managing different users by group and allocating corresponding system permissions to different user groups.

[0050] In the embodiment of the present invention, user management at least includes maintaining user information and verifying the legitimacy of user identity. User group management at least includes classifying different users by group, obtaining multiple user groups, maintaining information of each user group, and assigning corresponding system permissions to different user groups. In actual application, the system administrator can group users in the system, assign corresponding system permissions to each user group, and initiate requests for verification, addition, freezing, modification, retrieval, etc. of user information by displaying the front-end page of the MDC system. The user module 100 responds to the input request from the front-end system administrator, performs user grouping, assigns corresponding system permissions to each user group, and performs corresponding user information verification, addition, freezing, modification, retrieval, etc.

[0051] The system permissions assigned to each user group can be web page access permissions, with granularity down to buttons. For example, user groups can be bound to accessible buttons on accessible pages to achieve high-granularity management and control of user permissions.

[0052] The user module 100 implements user legitimacy verification, including: the user module 100 automatically associates the company domain account and loads the user information, and verifies the legitimacy of the user's identity based on the loaded user information. In specific implementation, the MDC system automatically associates the company domain account and loads the user information by calling the company domain account interface, and verifies whether the current user's identity is legal, such as whether the user is an employee of the company, based on the loaded user information. For new users, when the current new user's identity is verified to be legal, the new user can also be assigned to a user group.

[0053] The MDC system provided by the embodiment of the present invention can verify the legitimacy of newly added users by verifying the company domain account, preventing the problem of illegal identity not being recognized due to the addition of user roles without verification, thereby ensuring the security and stability of the system. In addition, users are managed by group classification, and different user groups are assigned corresponding system permissions, achieving the effect of access control of operation permissions based on user roles, solving the illegal operation problems caused by chaotic user management, imperfect user permission control, and insufficient granularity in existing data collection systems.

[0054] The equipment module 200 is used to manage production equipment information.

[0055] The production equipment information includes the production equipment name, equipment type, process category, etc.

[0056] In actual applications, the MDC system background periodically obtains online equipment information of the one-key automation system. In addition, the MDC system is connected to the CIM system, interacts with the CIM system in real time through Web Service, obtains the list of production equipment in the factory from http requests, and thus obtains accurate production equipment information.

[0057] The product module 300 is used to manage product information, wherein each type of product is associated with at least one collection form template.

[0058] Specifically in the embodiment of the present invention, the product module 300 implements the management of product information including:

[0059] ① The product module 300 maintains a product list, which represents the relationship between customers and products within the company; the product list is associated with product groups; the product list can be used as reference data for designing a collection form template;

[0060] ② The product module 300 manages different products by classification into groups to form different product groups, and each product group is associated with at least one collection order template.

[0061] In actual applications, system administrators can actively maintain product lists based on new product import information, or passively add product information based on system alarm prompts. System administrators can independently define product groups and associate products in the system based on collection orders and customer management requirements.

[0062] In the MDC system provided by the embodiment of the present invention, product management includes two management methods: product group management and product list management. The product list can be associated with the product group, and the product group is used to associate with the collection form template. This can effectively solve the user's subjective judgment of the collection form required for the product and avoid human errors and risks.

[0063] The parameter module 400 includes a parameter pool, and the parameter module 400 is used to manage the parameters in the parameter pool. The management method at least includes defining parameter attributes, and the parameter attributes include at least one of a parameter domain, a parameter name, a parameter type, and a parameter example; each parameter in the parameter pool is respectively associated with a process type or an equipment type.

[0064] In the embodiment of the present invention, the parameter module 400 includes a parameter pool, which is mainly used to implement the maintenance and management of the parameters in the parameter pool. In practical applications, the acquisition unit designer can independently define parameters according to the process he is responsible for, and the defined parameters form a parameter pool as the acquisition unit template parameter source. Specifically, defining parameters is specifically defining parameter attributes, and the parameter attributes include at least one of parameter domain, parameter name, parameter type, and parameter example. And each parameter in the parameter pool is associated with a process type or an equipment type, respectively. Among them, the process type or equipment type is used to limit the process to which the parameter belongs, the parameter domain is used to classify the parameters in the parameter pool, the parameter type is used to specify the parameter verification method, and the parameter example is used to limit whether the parameter collection needs to be photographed for evidence.

[0065] The template module 500 is used to implement the collection form template management, wherein each collection form template implements the association of products, equipment types / process types, parameters, and triggering methods through attribute definitions.

[0066] The collection order template management includes template creation, template modification, template preview, etc. Collection order designers can create collection order templates according to process control requirements, and associate the collection order template with product groups, equipment types or process categories, and set trigger methods. The trigger method is used to match the production operation of the operator, that is, the trigger method simultaneously associates the production operation of the operator and the collection order template. In actual applications, when the system detects the production operation of the operator, it will automatically trigger the creation of a collection order corresponding to the production operation. Trigger methods can include: product switching trigger, product verification trigger, product on-machine trigger, product off-machine trigger, equipment status abnormality trigger, etc.

[0067] In the practical application of the embodiment of the present invention, the template module 500 creates a collection form template including:

[0068] According to the received creation request, select parameters from the parameter pool to generate a first version of the collection order template;

[0069] The first version of the collection order template is associated with a product or product group, an equipment type or a process category, and a triggering method is set to form a final collection order template.

[0070] Preferably, the template module 500 is also used to implement template list management. The template list displays all the collection order templates that have been created in history. The collection order template can be modified, discarded, deleted, previewed, and manually triggered. The collection order template will be automatically upgraded after the change is approved, and the change record can be traced.

[0071] The embodiment of the present invention forms rules by defining the attributes of the collection form template (associated products / product groups, associated equipment types / process categories, associated parameters, setting trigger modes, etc.), the collection form template is created based on the process category, and the collection form template is associated with the parameters in the parameter pool, which is used to standardize the generation of the collection form template, thereby helping the integrated module 600 to realize the automatic creation of the collection form. Compared with the existing data collection system that requires operators to log in to the system at different production nodes, manually create collection forms corresponding to the production nodes, and manually enter the collection item information, the embodiment of the present invention realizes the automatic triggering and creation of collection forms based on the production operation of operators, with high accuracy and high collection efficiency. The present invention reconstructs the collection form design logic, abandons the Microsoft Excel module of the existing system, deeply understands the essence of the collection system, designs the parameter pool, and associates the process flow. The collection form designer does not need to spend time designing the collection form style, but only needs to create the collection form name, select parameters from the parameter pool of the process flow, and the system generates the collection form template in a standardized manner, which solves the problems of cumbersome and time-consuming collection form design (the collection form designer designs the row and column format based on subjective understanding), the problem of diversified formats of the same collection form, the large workload of the designer, and the large learning cost of the operator.

[0072] The integration module 600 is used to connect to the CIM system, automatically create a collection sheet according to the production operation information and product information transmitted by the CIM system, and automatically fill in the collection sheet information.

[0073] In the embodiment of the present invention, the integration module 600 is integrated with the CIM system based on the HTTP protocol, and the information interaction between the integration module 600 and the CIM system is transmitted through a standardized interface.

[0074] Preferably, in the embodiment of the present invention, the MDC system and the CIM system realize software integration, and the MDC system hardware is integrated with a product information entry device, and the product information entry device may include one of the following: a barcode scanner, an RFID (Radio Frequency Identification) card, and a PDA (mobile device).

[0075] In actual applications, the production operation information of users in the production process (such as line change, verification, product loading and unloading, etc.), as well as the product information collected by barcode scanners, RFID cards, PDA scanning, etc., are integrated and processed by the standardized interface and transmitted to the integration module 600. The integration module 600 automatically creates a collection form and automatically fills in basic information into the collection form with reference to the basic configuration data. Compared with the existing data collection system that requires manual information collection and entry into the system (for example, the operator observes the instrument parameters and opens the system to enter the control parameters), the present invention can ensure the accuracy and completeness of the collected information.

[0076] Figure 2The diagram shows the information interaction between the MDC system integrated with the CIM system software and the product information entry device hardware and the CIM system in the embodiment of the present invention.

[0077] In actual applications, the production operation information of users in the production process, such as switching products, verifying products, loading products on the machine, unloading products on the machine, querying collection orders, temporarily storing collection orders, submitting collection orders, etc., as well as the product information collected by the product information entry device, are sent to the CIM system together. The CIM system determines the triggering of the collection order and the collection order processing method according to the production operation information (corresponding to the triggering method set by the collection order template), such as creating a collection order, querying a collection order, temporarily storing a collection order, and verifying a collection order, and generates corresponding collection order processing requests, such as creating a collection order request, querying a collection order request, temporarily storing a collection order request, and verifying a collection order request, and sends the request together with the product information to the MDC system standardized interface, which is integrated and processed by the standardized interface and then transmitted to the integration module 600. Finally, the integration module 600 completes the corresponding collection order processing according to the collection order processing request and product information, such as automatic creation of the collection order, automatic filling of the collection order information, querying the collection order information, temporarily storing the collection order, and verifying the collection order.

[0078] The embodiment of the present invention combines the production operation information collection requirements with the manufacturing process, and creatively adds a "trigger mode" as a collection order trigger mechanism. In the normal process of chip production, the CIM system automatically identifies the production operation mode of the employees and triggers the MDC system to create a collection order, automatically fill in the basic parameters, check the key parameter items and feedback the results to ensure the quality of information. The integrated CIM system can automatically identify the product and process categories, accurately create collection orders, and avoid the problems of erroneous creation, non-timely creation, and inefficiency caused by employees manually creating collection orders. The MDC system provided by the embodiment of the present invention realizes software integration with the CIM system, and integrates a barcode scanner, RFID card, PDA, etc. in hardware to realize product information entry. The CIM system integrates product information and process flow information and transmits them to the MDC system through a standardized interface. The MDC processes, stores, renders and displays form information based on the MVC model, completely solves the "information island" problem, realizes data interoperability, and presents collection statistics in multiple dimensions, providing data support for problem analysis and production decision-making.

[0079] Further preferably, the integrated module 600 in the embodiment of the present invention can also be used to implement at least one of the following functions:

[0080] ① Retrieve unfinished collection forms and enter the parameters to be filled in for the unfinished collection forms in a timely manner;

[0081] ②Verify the correctness of the collection form in real time and set the alarm reminder mode;

[0082] ③After confirming that the collection form has been verified successfully, the collection form will be automatically closed.

[0083] In actual applications, operators can independently retrieve unfinished collection orders in the MDC system by operating the integrated module 600 embedded in the mobile CIM system, and enter the parameters to be filled in for the unfinished collection orders in a timely manner; verify the correctness of the collection order in real time and issue an alarm reminder; and automatically close the collection order after the collection order is successfully verified.

[0084] The embodiment of the present invention innovatively customizes the mobile version of the MDC system to achieve efficient operation. Based on PDA hardware, the integrated module 600 is customized and moved. In the normal process of chip production, the system automatically identifies the employee's operation mode (such as line change, verification, product loading and unloading, etc.) and triggers the integrated module 600 to create a collection order, real-time alarm for unprocessed collection orders, automatically fill in basic parameters, check key parameter items and feedback results to ensure information quality.

[0085] Further Figure 3 As shown, the MDC system provided by the embodiment of the present invention may further include: an approval module 700 and a dashboard module 800 .

[0086] The approval module 700 is used to receive and display parameter-related requests initiated by the parameter module 400, and / or collection order template-related requests initiated by the template module 500, and receive and feedback the request response results of the operator;

[0087] The parameter-related request includes at least one of the following: creating a new parameter, modifying a parameter, or deleting a parameter;

[0088] The collection order template related requests include at least one of the following: creating a new collection order template, modifying a collection order template, discarding a collection order template, deleting a collection order template, previewing a collection order template, and manually triggering a collection order template.

[0089] The dashboard module 800 is used to display the manufacturing data collection status in multiple dimensions in combination with charts.

[0090] Specifically, the approval module 700 mainly implements parameter pool maintenance and collection form template maintenance, which specifically involves the approval of operations such as creating new parameters, modifying parameters, deleting parameters, and the approval of operations such as creating new collection forms, modifying collection forms, discarding collection forms, deleting collection forms, previewing collection forms, and manually triggering collection forms. In actual applications, operators input parameter-related requests / collection form template-related requests through the front-end page, such as creating new parameters / creating new collection forms. The parameter module 400 / template module 500 sends the corresponding request to the approval module 700, and the approval module 700 displays the request in the approval list for approval by the approving personnel. Once a parameter item or collection form template is submitted for approval, its status will change to "pending approval". After the approval is passed, the status will change to "effective" and the version number will be automatically advanced.

[0091] The embodiment of the present invention sets the approval module 700 to determine that parameter changes and collection form template changes must go through the approval process, which can effectively avoid the problem of users arbitrarily changing collection form templates and parameters without quality control.

[0092] The MDC system and the CIM system are integrated and interactive, and the MDC system can efficiently collect a large amount of manufacturing data. The Kanban module 800 extracts, cleans, integrates and applies these data, and displays the manufacturing data collection status in multiple dimensions in combination with charts. Through reasonable database design in the embodiment of the present invention, the Kanban module 800 can efficiently extract data and present the collection status of the collection order in multiple dimensions, such as presenting the completion status of the collection order based on the equipment type or process category dimension, tracking the data collection records in the process flow based on the product number dimension, quantitatively displaying the repeatedly submitted templates based on the template dimension, and obtaining the alarm parameter items based on the parameter dimension.

[0093] Figure 4 The data flow diagram of the MDC system in the embodiment of the present invention is shown.

[0094] Different identities of operators have different corresponding system permissions. For example, the administrator's system permissions correspond to all modules in the MDC system, the product engineer's system permissions correspond to parameter module 400 and template module 500 in the MDC system, the approval personnel's system permissions correspond to approval module 700 in the MDC system, and the foreman's system permissions correspond to template module 500 in the MDC system. The MDC system supports responding to the operation requests of operators and saves all operation information and result records to the MDC database. At the same time, the production operation information of production personnel, such as switching products, verifying products, putting products on the machine, taking products off the machine, equipment offline, and replacing materials, will enable the CIM system to determine the triggering of the collection order, and send the determined collection order processing method, such as creating a collection order, and the collected product information to the MDC system through a standardized interface. After the MDC system responds, it will also save the response result record to the MDC database.

[0095] Compared with the existing system, the MDC system provided by the embodiment of the present invention can automatically, intelligently, accurately and efficiently create manufacturing data collection orders based on the complex process flow of semiconductor chip production, greatly improving the efficiency of collection order generation, collection and closing, and reducing production costs. At the same time, the MDC system has the characteristics of standardized interfaces, high application availability and load balancing, and sustainable deployment. It can efficiently support data collection, transmission, identification and utilization under the complex process flow of semiconductor packaging and testing plants 24 hours a day, 7 days a week, meeting the high requirements of modern semiconductor intelligent manufacturing. Its advantages are specifically reflected in the following aspects:

[0096] 1. Improve the work efficiency of the engineering team: introduce concepts such as parameter pool and collection template. Process engineers do not need to spend time designing the collection form. They only need to associate the corresponding parameters in the parameter pool based on the collection template name to automatically generate the template;

[0097] 2. Improve the work efficiency of production operators: introduce the concept of trigger mode to automatically and accurately create collection orders, avoiding problems such as manual creation, erroneous creation, and missed creation in the existing system;

[0098] 3. Reduce production costs: Integrate the CIM system to achieve truly accurate creation, automatic filling, and paperless records, greatly saving labor costs and time costs;

[0099] 4. Enhanced quality control: The MDC system provides a quality measurement index setting area for key parameters, verifies collection items in real time, alarms for items that exceed the index, and performs process card control on the corresponding products, which greatly reduces the quality risks brought about by manual recording, delayed filling, and no process control in the existing system;

[0100] 5. Enhance user response capabilities: Based on data analysis and statistics, user collection records can be traced. Combined with front-end display technology, multi-dimensional graphical collection form filling status provides a solid basis for user departments to analyze operator performance, process improvement and other decisions, greatly enhancing user decision-making capabilities;

[0101] 6. Realize resource conservation: The MDC system is integrated into the factory manufacturing system, and data intercommunication is achieved through standardized interfaces, virtualization and container technology are used to save technical resources, and NGINX technology is used to achieve load balancing and high availability. This solves the problems of "information islands", bloated data, unstable performance, and waste of technical resources in existing technologies or systems.

[0102] 7. Improved operation and use: The MDC system is based on access control, customizes access rights for multiple roles, streamlines the user interface, simplifies the operation steps, and users can complete specific tasks with one-click submission, which greatly improves user experience and user satisfaction.
