Wafer Testing Information Management System Process Reform Implementation Research Of DUT

The integrated circuit industry has been the fundamental part in economic development, which was prioritized and supported by our nation. Since 2013 the national level brewing support integrated circuit industrial policy was released in 2014, clearly elaborate about the industry’s importance in safeguard national security. But by historical and structural reasons, China’s IC industry still faces great pressure in the industry competition and some other advanced countries and regions of the despite of development & remarkable progress in the past 15 years.Wafer testing industry belongs to the backend of integrated circuit industry in the semiconductor supply chain, also a relatively low barriers to entry, relatively faster scale formation possibility, however still play a decisive role within the industry. Therefore it became a breakthrough point in the in industry chain. During the industry fast growing process, we find a truth that, how to provide customers the most effective information, allowing customers to decide the optimal methodology as soon as possible, is best powerful weapon to compete in the industry and win business opportunities, market share.In this research, through the analysis of the present situation of information system management of case enterprises, we discusses the related theory of RFID and the semiconductor industry practical application cases; Then detailed analyze enterprise newly introduced "RFID based wafer test real-time information sharing system", which was composed by supply chain logistics information management, inventory management, the accurate inventory data system. Carried out the feasibility analysis above three system, and put them into practice. Based on the analysis of the benefit from implementation of the system, to verify the feasibility of wafer testing into RFID in the actual production environment applications, by consolidation of RFID and information management system, reduce the operation time and improve production efficiency, precise control of WIP flow, improve the operation process. Therefor strengthen the operation process monitoring and analysis, provide information in order to benefit enterprise management by providing assistance when making decisions. Also the study proposes on the improvement and development direction to the future, reference as the foundation to continue to improve in future reference for Industry and other enterprises.
