The Research On Process Optimization Of S Semiconductor Company In Memory Chip Assembly And Testing Area

Semiconductor manufacturing as high technology industry,take a very important role in the social economic,and solid state hard disk(SSD)have been become very hot topic in the semiconductor segment.Recently the requirement of cloud computing and Big Data Applications,the demand of memory chip have been reached a high level.As a memory chip manufacturing company,it is urgent to extend the manufacturing capability,and take the more market share,that is very critical to keep the advantage in the future competition.But there is also some limitation for semiconductor manufacturing process,how to optimize and adjust the management style is a very critical topic to the manufacturing company.This paper take the S Company as an example,to analysis the manufacturing process of assembly and testing area,and find the deep details of the lights off manufacturing mode,build a solution to optimize the process based on the company manufacturing data.And we also provide a solution to optimize the company information technology service workflow.This Paper analysis the feature of the semiconductor manufacturing process,and point out the manufacturing process issue based on the lights off manufacturing mode,and also explain why we need to optimize the semiconductor assembly and testing work process.Based on the summarized international and domestic process optimize theory and principals,evaluate the value of the process optimization,and find out a way to realize the process.Based on the S company manufacturing features,built a model to matching the order number between the wafer die quantity and the strip quantity.And also built a virtual wafer testing process to lower down the wafer physical moving numbers.Beside that also analysis the information system service work flow and provide an optimization solution.At last also evaluation the whole process optimization result based on the S company manufacturing data.Finally,we take a look of the future of big data application in the semiconductor manufacturing process,the new technology will be take more and more important role,and the intelligent manufacturing mode will affect the business competitions.
