半导体行业观察·2025-05-26 00:50Core Viewpoint - The semiconductor industry is characterized by a complex, interwoven global supply chain, making unilateral actions by either the US or China difficult in their competition for chip manufacturing dominance [1][2]. Group 1: Supply Chain Dynamics - The semiconductor production process relies on a global network for mining, design, manufacturing, packaging, and testing, with certain countries and companies holding proprietary technologies that dominate the market [1]. - Ultra-pure quartz, essential for semiconductor production, is primarily sourced from a single location in North Carolina, which supplies about 90% of the global ultra-pure quartz [1]. Group 2: Market Share and Competition - Shin-Etsu Chemical holds approximately 30% of the global wafer market, establishing itself as a leader in the industry [1]. - TSMC commands a significant 67.1% share of the global foundry market, followed by Samsung at 8.1% and China's SMIC at 5.5%, collectively accounting for over 80% of the market [2]. - The concentration of market power is expected to persist as leading companies continue to invest heavily in research and development, making it challenging for new entrants to disrupt their dominance [2].
