In common with a number of other developing industries, the growing significance of IC industry development in Taiwan is notable for its CSFs that have helped it develop from labor-intensive, technology-intensive and capital-intensive stage during the 1970s to the highly profitable period of the 1990s. This paper identifies palpable correlationships of extracting factors among the dependent stages by factor analysis through an empirical work. Manufacturing capability is the only common extracting factor among all stages. Notably, six sets of extracting factors are two stages dependent. One stage dependent takes technology migration and market requirement extracting factors in the 1970s; unique characteristics of family-like culture extracting factor in the 1980s; and six extracting factors in the 1990s, namely: powerful industrial talent, strategic alliances, development momentum based on entrepreneurship and so on as the unique stage dependent factors that drive the development of each stage of the Taiwanese IC industry.
