Core Viewpoint - The article emphasizes the critical role of photoresist in the semiconductor industry, highlighting the risks posed by the current reliance on foreign suppliers, particularly Japan, which dominates 90% of the high-end photoresist market. The potential for supply disruptions could severely impact China's semiconductor capabilities, especially in advanced processes below 14nm [2][11][23]. Group 1: Importance of Photoresist - Photoresist is described as an essential material in semiconductor manufacturing, likened to a precision tool that enables the creation of intricate circuit patterns on silicon wafers [4][11]. - The production of high-end photoresist involves complex chemical formulations and stringent manufacturing processes, making it a highly specialized field with significant technical barriers [7][23]. Group 2: Current Market Situation - China's domestic production of high-end photoresist is alarmingly low, with KrF photoresist at 15% and ArF photoresist below 5% [2][11]. - The article outlines various types of photoresist used in semiconductor manufacturing, including G-line, I-line, KrF, ArF, and EUV photoresists, each serving different technological nodes [8][10]. Group 3: Risks of Supply Disruption - The article discusses potential scenarios of supply disruption due to geopolitical tensions, particularly the risk of a comprehensive technology embargo from the U.S. and its allies, which could lead to a halt in semiconductor production in China [27][28][29]. - The impact of such disruptions would be felt across various sectors, including automotive, consumer electronics, and advanced computing, leading to significant economic repercussions [33][34][38]. Group 4: Strategies for Mitigation - The article suggests immediate emergency strategies, such as inventory management, global sourcing through gray channels, and temporary use of lower-performance alternatives to maintain production [42][44][45]. - Long-term strategies include building a self-sufficient photoresist supply chain through national collaboration, technological innovation, and investment in research and development [51][55][58]. Group 5: Future Outlook - The article concludes that while the current situation poses severe challenges, it also presents an opportunity for China to strengthen its semiconductor industry by investing in domestic capabilities and reducing reliance on foreign technology [62].
