The Design And Implementation Of Manufacturing Execution System For Circuit Probing

With the popularity of consumer electronics,semiconductor industry in China has developed rapidly.Circuit probing is an important step in the semiconductor manufacturing process.It has many characteristics,such as complex production process,frequent product updating and fierce competition in the industry.MES is the abbreviation of manufacturing execution system.It is an information management system for manufacturing enterprise.In order to manage the production process,shorten the production cycle,avoid human error and improve productivity,this paper designs and implements a MES for circuit probing.Firstly,this paper describes the research background of the subject,and analyzes the great significance of MES in circuit probing.It introduces the research status at home and abroad,and clarifies the main tasks of this subject.Secondly,according to the working principle of the system,the function modules of the system are divided.The functional requirements and non-functional requirements of the system are analyzed and the user’s permissions are divided.Thirdly,the software architecture is designed.In B/S mode,we use Java Web programming,and MySQL database.In the Domain Driven Design,we use open source framework Spring MVC + Spring + Hibernate.The software of the system is divided into 5 layers,which are view layer,controller layer,application layer,domain layer and infrastructure layer.Manufacturing execution system for circuit probing is divided into production management subsystem and data monitoring subsystem.The production management subsystem consists of 4 modules,which are wafer management,process management,circuit probing and exception handling.We carry out the overall design.Then for each module,introduce the working principle,design the relationship between the classes,show the front page,and realize the function of production management.The data monitoring subsystem is composed of output monitoring module and report module.Introduce the structure of data monitoring subsystem and the source of data.For each module we select the appropriate tools,design the format of the data,through the front page display,achieve the function of output monitoring and reporting.This paper realizes the production management and data monitoring in the circuit probing process.It has a certain practical function to improve the productivity and reduce the production cost.
