Core Viewpoint - The PSPI (Photosensitive Polyimide) market is projected to grow significantly, with a global market size expected to reach $402 million in 2024 and $802 million by 2030, driven by high technological barriers and market monopolization by major players [2][3]. Industry Overview - PSPI is a high-performance polymer material that combines the excellent dielectric properties, mechanical strength, and heat resistance of polyimide with the photosensitivity of photoresists, playing a crucial role in semiconductor packaging and advanced packaging processes [1]. - The PSPI market is dominated by five major companies, including Toray, Fujifilm Electronic Materials, HD Microsystems, Asahi Kasei, and SK Materials, which collectively hold approximately 95% of the global market share [2][3]. Recent Developments - On July 10, 2023, Jilin Aolide Longxin Materials Technology Co., Ltd. commenced a project for the R&D and industrialization of key functional materials for OLED displays, with a funding target of up to 299.86 million yuan for the PSPI materials production base [4]. - In July 2023, Toray announced the successful development of STF-2000, a photosensitive polyimide that can achieve fine processing on films up to 200 micrometers thick, with a line width of 30 micrometers, expected to be mass-produced by 2025 [4]. - Asahi Kasei announced a supply cut for its core PSPI product (PIMEL) in May 2023, indicating potential supply chain disruptions in the market [4]. - Hubei Dinglong Holdings Co., Ltd. reported plans to increase its production capacity, with a target of 40,000 polished hard pads per month by the end of Q1 2025 and the launch of a 1,000-ton PSPI production line [4].

Core Viewpoint - Asahi Kasei's supply adjustments of PSPI materials have significant implications for the global semiconductor industry, highlighting the tension between surging AI computing demands and limited production capacity [1][2]. Group 1: PSPI Material Overview - PSPI (Photosensitive Polyimide) is a high-performance polymer material that combines excellent dielectric properties, mechanical strength, and heat resistance with photosensitivity, playing a crucial role in semiconductor packaging and advanced packaging processes [3][5]. - The global market for PSPI materials is projected to reach USD 402 million in 2024 and USD 802 million by 2030, with major suppliers dominating approximately 95% of the market share [5][9]. Group 2: Domestic Market and Companies - The domestic PSPI market in China is expected to reach RMB 820 million in 2024, driven by the increasing demand for AI computing chips and advanced packaging technologies [9]. - Key domestic players in the PSPI market include Bomi Technology, Dinglong Holdings, Aisen Semiconductor, and Shengquan Group, with various companies actively developing and producing PSPI materials [10][11][12][13]. Group 3: Company Highlights - Bomi Technology has achieved mass production of PSPI materials and is involved in a national key research project for 2.5D/3D packaging technology [10]. - Dinglong Holdings has developed multiple semiconductor packaging materials and is set to begin mass production in 2024 [11]. - Aisen Semiconductor is launching its first domestic positive PSPI product in 2024 and is also working on various other PSPI types [12]. - Shengquan Group has established a pilot line for PSPI and plans to expand production significantly by 2025 [12].
