半导体材料：10000字详解中国光刻胶产业发展现状

Group 1 - The global photoresist market is expected to grow at an annual rate of approximately 5% from 2022 to 2027, despite a 2% decline in 2022 due to a drop in demand from the new display industry [4][9] - In the semiconductor sector, the global market size reached $573.5 billion in 2022, with a year-on-year growth of 3.2%, and the consumption of photoresist was approximately 23.8 billion yuan, an increase of 8% [5] - The new display panel market saw a decline in output area by 4.3% in 2022, leading to a 19% decrease in photoresist consumption in this sector [6] Group 2 - China's photoresist demand is projected to grow at an average annual rate of 7% from 2022 to 2027, despite a stagnation in 2022 [9] - In the semiconductor field, China's actual production capacity for 12-inch wafers reached 1.37 million pieces per month in 2022, with a year-on-year growth of 32% [10] - The consumption of photoresist in China's semiconductor industry was 4.6 billion yuan in 2022, reflecting a 15% increase [10] Group 3 - The domestic photoresist production capacity is significantly lower than market demand, with most production focused on PCB photoresist [14] - High-end photoresist products are still largely dependent on imports, with the most advanced domestic semiconductor photoresist being KrF photoresist [15][19] - The key raw materials for photoresist production are primarily imported, leading to a low domestic production rate for these materials [16][31] Group 4 - Several domestic companies have achieved breakthroughs in the production of G/I line photoresists, with KrF photoresist seeing some mature products [19][23] - The TFT positive photoresist market is dominated by foreign companies, with domestic suppliers achieving a 20% market share [26] - The PCB photoresist market is characterized by a tripartite structure among Japan, Taiwan, and mainland China, with domestic companies achieving a 55% localization rate for wet film photoresist [29][30] Group 5 - The Chinese photoresist industry faces significant challenges, including a large technological gap and weak engineering capabilities [37] - The reliance on single-source imports for key raw materials and equipment poses a high supply chain risk for the industry [38]
