| Summary: | 碩士 === 國立臺灣大學 === 經濟學研究所 === 105 === Over the past decades, DRAM Industry has played a significant role in the Global Economy. High Capex is the feature of this industry which becomes the barrier to entry and exit. After being through the Global Bank Crisis in 2003 and Financial Crisis in 2008, this industry has been turned into Oligopoly status of High Concentration. Top 3 makers reach above 90% makert share; Powerchip and ProMOS in DRAM Industry are both facing the difficulties. However it comes up with different results after business transformation finally.
This paper started from the development of global Semiconductor industry then contracted to the current situation of DRAM market. The research reviewed Competitive Strategies, Five Force Model, FRSA to Business Analysis to explore the Business Model of DRAM makers. On the basis of Enterprise Competitive Advantage, the local DRAM makers: Powerchip and ProMOS are the subjects of case study.
The research indicates the difference between Powerchip and ProMOS is the Source of Technology Transfer. Powerchip has always remained the same source but ProMOS has been through different several resources. In the end, Powerchip turns into Foundry Compnay and ProMOS turns into IC design house.
For future research, the Anaylsis of Competitive Strategies based on Oligopoly of high concentration would be highly recommended. Secondly, research how to maintain the Enterprise Competitive Advantage except technological advantage.
