dc.description.abstract | Electronics industry is very important in every country, and the semiconductor industry is the key point for the electronics industry. The rapid growth of semiconductor technology also changes defense, communication, information, transportation, and consumer electronics industry. In recent years, fab construction and process technology R & D costs rising, many of the traditional IDM(Integrated Device Manufacturer)companies will continue manufacturing outsourcing, head towards to be a Fab-lite and Fabless company. Foundry, this business model created by the Taiwanese manufacturer makes IC design industry growing. Two professional IC design companies: Qualcomm and Broadcom, are promoted to the top 10 semiconductor company in 2011. Huge capacity demand from IDM and IC design companies usually makes the production of foundry in short supply, therefore timely to improve productivity and meet customer demand is an important lesson for the foundry.
Large amount of investment in the semiconductor industry is necessary. An eight-inch fab costs about $ 1 billion, 80% for manufacturing equipment (about NT $20 billion) and from equipment installation to trial production will take more than three months. Prosperity of semiconductor industry changes very quickly, every semiconductor company is facing severe challenges, it’s very cautious to construct a new fab or to purchase new manufacturing equipment. Therefore, to increase productivity of existing machines is more important to semiconductor fab to reduce costs and enhance competitiveness. This study attempts to identify the factors of poor equipment efficiency then improve it to increase productivity and competitiveness of semiconductor companies.
High current ion implanter in A Company, fab 5, is the topic in this study. A company is a professional foundry, its fab5 was often unable to meet the customer’’s capacity requirements because the high current ion implanter was the production bottleneck. For this reason, we set up a team to analyze this problem in Ford-8D procedures. Ford-8D uses eight basic criteria to solve the problem. To solve problem, we first identify the root cause of problem, and propose short, medium and long-term plans and take appropriate action. This study provides a practical case to understand how to use 8D method to improve productivity and also be a reference to solve the problem.
