説明

Different from adopting the conventional "vertical integration" concept, Taiwanese Semiconductor Industry is fast developing a new industrial structure, "vertical disintegration" which emphasizes on the specialization of each semiconductor manufacturing process. Such approach raised the attentions both in academic and in practice. As a result, a rich body of research about Taiwan's Semiconductor Industry started surfacing. Most research emphasized on the policies of Taiwanese government, e.g., how to promote the development of the semiconductor industry, how they can be the world industry leader, etc. I, however, proposed urgent needs for studies to investigate the issues of competitive advantages of the semiconductor firms, especially those of the semiconductor foundry. I performed in depth case study analyses of two major Taiwanese firms. The results addressed several such issues and provided insights to this new structure and I linked its characteristics to business performance and success. The study has three major findings. First, TSMC and UMC remained in leading positions not just by having productive capability, product technology capability, and design service support capability, but also by having an excellent productive process system and a knowledge management system. Second, TSMC and UMC integrated design and manufacturing functions into the firms, and built a platform of optimum production system and opened this optimum platform to all customers worldwide to acquire the economies of scale and scope. Third, compared with the IDM companies, I found that, Taiwanese semiconductor foundry showed the characteristics of a destructive innovation, termed "New-Market Destructions Type", and these characteristics led to business success.
