Development Of The IC-CAM System Based On B/S And C/S Mixed Architecture

Computer-aided manufacturing(CAM) refers to how to use computer technology effectively through direct or indirect combining computer and material resources manpower resources of one enterprise, in such aspect as plan, management, cantonment, operation, etc. When CAM is used in integrated circuit (IC) manufacturing, we call it IC-CAM. At present, both integrated circuit computer-aided design(IC-CAD) technology and integrated circuit computer-aided manufacturing technology in our country are inferior to that of advanced country. If we use IC-CAM system to manage IC manufacturing, our IC manufacture will be advanced. Furthermore, IC-CAM will increase the yield and decrease the cost of the products, and help to gain the certification of ISO 9000 quality system. So it's necessary that the semiconductor manufacturing enterprise in our country should use IC-CAM technology.Based on the IC-CAM system of Tsinghua's and HongKang's IC manufacturing fab, Microelectronics R && D Center ,Chinese Academy of Science designed one new IC-CAM system according its own condition. This new IC-CAM system is based on C/S and B/S mixed architecture, so its data information not only can be browsed in the web but also can be shared in local area network. In the configuration, the ORACLE7.3 DBMS operates with SCO Unix platform at the server end and application programs create with Power Builder kit on Windows98/xp/2000 work at the client end. The system composed of eight- subsystem covers all the departments of the pilot line.The design of the IC-CAM system relates to some technologies, such as Unix Oracle Powerbuilder and the processing of IC manufacturing. This paper begins with an introduction of database technique, Afterwards, it illuminated the client/server and browser/server mix architecture ,Then the design idea and application technologies of the IC-CAM system are analyzed. At last, the characteristics and the results of running the new IC-CAM system are concluded, and some ideas of improving IC-CAM systems are proposed.
