Core Viewpoint - The recent supply disruption of CMP slurry, specifically DST slurry produced by AGC in Taiwan, has accelerated the pace of domestic alternatives in the semiconductor industry, highlighting the urgency for local manufacturers to innovate and adapt [1][2]. Group 1: Importance of CMP Slurry - CMP slurry is essential for the chemical mechanical polishing process in semiconductor manufacturing, akin to smoothing and leveling surfaces in construction [2]. - The slurry consists of ultra-fine abrasives, chemical agents, and water, and is crucial for achieving the required surface smoothness in logic and memory chip production [2]. Group 2: Market Dynamics - The CMP slurry market is predominantly controlled by American and Japanese companies, with Cabot Microelectronics holding 33% of the global market share, while Japanese firms account for an additional 23% [3]. - Domestic manufacturers currently hold a market share of 25-30%, which is even lower in high-end processes (e.g., below 28nm) [3]. - The global CMP slurry market was valued at $1.89 billion in 2021 and is projected to exceed $2.6 billion by 2026, with a compound annual growth rate (CAGR) of approximately 6% [3]. - In China, the CMP slurry market is expected to grow from approximately 2.3 billion yuan in 2023 to 4.6 billion yuan by 2028, reflecting a CAGR of 15% [3]. Group 3: Demand Surge Factors - The demand for CMP slurry is increasing due to the growing complexity of high-end processes, with the number of CMP steps for 14nm logic chips doubling, requiring more types of slurry [3]. - The rise of 3D NAND memory chips, with increasing stacking layers, necessitates more intricate polishing processes, leading to a significant increase in CMP slurry usage [3]. Group 4: Domestic Players - Anji Technology has been a leader in CMP slurry since 2006, achieving a market share of over 5% globally and increasing its share in China from 20.9% in 2020 to 30.8% in 2021 [4]. - Sanhe New Materials focuses on diamond polishing liquids for hard materials and is gradually increasing its market share by supplying to companies like SMIC [4]. - Dinglong Co. is a key player in the domestic polishing pad market, offering a comprehensive solution that includes polishing liquids, cleaning liquids, and polishing pads, enhancing its competitive edge [5].
