Research On Improvement Of Production Quality Management Of IIT Corporation

With people's demand on product quality become higher and higher,the competition of product quality among enterprises is increased.The control and improving the quality of products not only reduce the costs,but also make enterprise in a favorable position in the fierce competition.Semiconductor industry has characteristics of high technology integration,complex process,rapid technology refresh,high investment,high cost and long product cycle time,and so on,all these make enterprises have higher requirement on the technology process and quality.The quality of semiconductor products is not only the lifeblood of enterprises,but also related to the electronic equipment enterprises' survival and development.As the semiconductor industry in China's mainland started late and the technology of process has relatively fallen behind,therefore,it is especially important to strengthen the control of the product quality and improve the product quality management for the development of enterprises.Based on the study of relevant theories of quality management,this thesis makes an in-depth research and exploration on the existing production management problems of IIT company's only non-volatile memory chip Dalian factory,and analyzes the existing problems and related reasons of IIT company such as high frequent equipment problems,unstable product yield and increasing product scrap issues.Using quality management control methods,statistical process control,FMEA,error-proofing methods and others methods,the rectification scheme has put forward to optimize the quality management organization structure to make the resource allocation more reasonable,improve the corresponding quality management control methods,perfecting the error-proofing,and make the product quality control more reasonable.Finally,the quality management guarantee are proposed to protect the application of IIT quality management.By studying the quality management of IIT company,this thesis puts forward the problem,analyzes the problem and proposes the solution to the analysis according to the relevant theory and actual situation,establishes and perfects the quality management method and system of the company.The proposal and implementation of safeguard will further consolidate the quality management of this company.Meanwhile,the problems and methods of how to resolve,which mentioned in thesis has been representative in wafer fabrication industry,can be of a good reference for others factory.
