证券日报网讯 1月7日，广信材料在互动平台回答投资者提问时表示，据了解，截至目前在PCB光刻 胶、显示光刻胶、集成电路光刻胶等传统光刻胶主流供应商仍以日韩企业为主，其中国产化率最高的 PCB光刻胶依旧有一半以上市场份额仍被日资企业占领，存在很大替代空间。经过多年的发展，公司在 光刻胶板块以PCB光刻胶为基本盘稳健增长、适时拓展光伏胶等泛半导体领域，目前已成为PCB光刻胶 领域内资头部企业、光伏胶等泛半导体领域领跑企业。随着公司龙南基地已经逐步试生产及公司产能资 产进一步优化，经营水平、研发水平、市场开拓的不断提升，将进一步支撑公司在相关领域的业务增 长。 （文章来源：证券日报） ...

Core Viewpoint - The global and Chinese photoresist market is experiencing growth driven by the semiconductor and display panel industries, with future demand expected to increase significantly despite recent fluctuations in specific sectors [5][10]. Group 1: Global Photoresist Market Overview - The global photoresist market size is expected to grow at an annual rate of approximately 5% from 2022 to 2027, despite a 2% decline in 2022 due to decreased demand in the new display industry [5]. - In the semiconductor sector, the global market size reached $573.5 billion in 2022, with a year-on-year growth of 3.2%, and photoresist consumption in this sector was approximately 23.8 billion yuan, growing by 8% [6]. - The new display panel market saw a decline in 2022, with a total shipment area of 237 million square meters, down 4.3%, leading to a 19% decrease in photoresist consumption to about 12.6 billion yuan [7]. - The PCB industry is projected to grow at an average annual rate of 4% from 2022 to 2027, with photoresist consumption in this sector reaching approximately 16.3 billion yuan in 2022, a 2% increase [9]. Group 2: Chinese Photoresist Market Overview - China's photoresist demand is expected to grow at an average annual rate of 7% from 2022 to 2027, despite the market size remaining stable in 2022 compared to 2021 [12]. - In the semiconductor sector, China's photoresist consumption reached 4.6 billion yuan in 2022, with a growth rate of 15%, and is expected to grow at 10% annually over the next five years [13]. - The new display sector in China saw a decline in photoresist consumption to 6.1 billion yuan in 2022, down 13%, but is projected to grow at 8% annually in the coming years [14]. - The PCB industry in China had a total output value of $43.6 billion in 2022, with photoresist consumption reaching approximately 10.1 billion yuan, a 3% increase [16]. Group 3: Development Status of China's Photoresist Industry - The domestic production rate of photoresists is relatively low, with significant reliance on imports for semiconductor and display panel photoresists [19]. - Several domestic companies have made progress in the production of G/I line photoresists, with KrF photoresists seeing some successful local production [25]. - The market for TFT positive photoresists is dominated by foreign companies, with domestic production accounting for about 20% of the total market [32]. - The PCB photoresist market is characterized by a growing domestic supply of wet film photoresists and imaging solder masks, with a current domestic production rate of approximately 55% [36]. Group 4: Challenges and Future Prospects - The high technical barriers in the photoresist industry and the need for collaboration with lithography equipment manufacturers pose challenges for rapid domestic development [19]. - There is a significant opportunity for domestic companies to increase their market share in high-end photoresists, as the current production capabilities are still limited [42]. - Ongoing projects in China aim to enhance the production capacity of photoresists and related materials, indicating a strong push towards achieving greater self-sufficiency [41].
