Core Viewpoint - The domestic high-end photoresist resin materials are entering a significant development period, with the successful establishment of the first domestic 100-ton semiconductor KrF photoresist resin production line, breaking the market monopoly of international giants [2][19]. Industry Background - The photoresist industry is categorized into three main types: new display photoresists, integrated circuit photoresists, and PCB photoresists, with integrated circuit photoresists having the highest technical barriers and market potential [3]. - The global market for integrated circuit photoresists is expected to exceed $40 billion by 2025, reflecting a year-on-year growth of 9% [3]. Market Dynamics - The global photoresist market is dominated by a few companies from Japan and the US, with a market concentration of about 90% in the integrated circuit sector [7]. - As of 2024, China's self-sufficiency rate for KrF/ArF photoresists is less than 5% [8]. - Japanese companies, including TOK, JSR, and Shin-Etsu Chemical, hold approximately 70%-80% of the global market share in high-end integrated circuit photoresists [9]. Domestic Production Capacity - China's production capacity for photoresists is primarily focused on PCB and new display products, with a low proportion of integrated circuit photoresists [5]. - The domestic market share for KrF photoresists is about 5%, while ArF photoresists account for approximately 2% [10]. Technological Challenges - The production of photoresists requires high purity and stability of raw materials, which include resins, photoinitiators, solvents, and monomers [11]. - The domestic industry is lagging in the industrialization capabilities of monomers, which are crucial for resin synthesis [13]. Market Growth Potential - The market size for KrF and ArF photoresists has grown from 1.47 billion yuan in 2019 to 3.67 billion yuan in 2023, with projections to reach 10.69 billion yuan by 2028 [17]. - The domestic company, Eight Billion Space, has successfully entered the "100-ton" supplier tier, providing critical support for domestic semiconductor materials [19].

Core Viewpoint - The company Eisen Co., Ltd. (688720.SH) has released an investor relations activity record indicating that its KrF photoresist AR has a high aspect ratio (>13), primarily used in high aspect ratio structures such as CIS isolation and corresponding structures in memory chips. The next step involves testing at leading wafer fabs [1]. Group 1 - The KrF photoresist AR has an aspect ratio greater than 13 [1] - The primary applications include CIS isolation and structures in memory chips [1] - Upcoming tests will be conducted at leading wafer fabs [1]

Core Viewpoint - Guangxin Materials held a performance briefing on November 4, 2025, discussing its business operations, core business progress, and future strategic plans with investors [1] Business Progress - The company has developed environmentally friendly graphene water-based coatings and solvent-free high-solid coatings for the marine anti-corrosion market, which have passed NORSOK M-501 standard testing and some customer site tests. These products are applicable to high-end marine equipment such as offshore oil and gas platforms and wave energy generation equipment. The company expects to achieve bulk sales in strategic core markets between Q4 2025 and Q2 2026 [2] Capacity and Performance - The Longnan base achieved over 150 million in revenue in the first three quarters of 2025. The company reported a net loss of 4.77 million in Q3 2025, primarily due to lower-than-expected revenue from photovoltaic BC battery insulation glue, fixed asset depreciation from the Longnan base, and impairment losses from the sale of a subsidiary. However, excluding credit and asset impairments, the company showed slight operational profitability [3] Strategic Focus - The company has been divesting loss-making assets such as Shenzhen Lejian and Hunan Sunshine to optimize its structure and reduce operational costs. The sale of a subsidiary for 9.8 million is part of this strategy. The company emphasizes that these transactions will not significantly impact production operations. The photolithography and related materials segment is benefiting from PCB market growth driven by AI and robotics, with a focus on providing cost-effective solutions. The company has completed a refinancing process for specific stock issuance in 2024 and currently has no other refinancing plans [4]

Core Viewpoint - The article discusses the significant progress made by Chinese companies in the development of photoresists, a critical material for semiconductor manufacturing, while highlighting the substantial gap that still exists compared to Japanese firms in terms of technology and market share [1][13][18]. Group 1: Importance of Photoresists - Photoresists are essential materials used in the photolithography process of chip manufacturing, impacting the yield and quality of end products [6][7]. - The market size of photoresists is closely linked to the manufacturing capabilities of smart equipment, making it a key indicator of semiconductor technology levels [7][9]. Group 2: Progress in Domestic Production - Over the past two decades, China has prioritized the development of the photoresist industry, with significant policy support aimed at achieving domestic production [7][12]. - By 2023, the domestic photoresist market is estimated to be around 12.1 billion yuan, with a projected compound annual growth rate of 10% over the next five years [13]. Group 3: Comparison with Japan - Despite progress, China's photoresist production remains significantly behind Japan, with domestic high-end photoresist localization rates being extremely low, particularly for EUV photoresists [13][15]. - Japanese companies dominate the global market, holding over 90% market share in high-end photoresists, with four out of the five largest manufacturers being Japanese [13][15]. Group 4: Barriers to Entry - Japanese firms have established strong technical, industry, and market barriers, making it difficult for new entrants to compete [18][20]. - The historical development of technology and the establishment of deep collaborations with downstream wafer manufacturers have solidified Japan's leading position in the photoresist market [20][21]. Group 5: Future Directions for China - To break the monopoly and reduce the gap with Japanese companies, Chinese firms need to enhance R&D efforts and focus on mastering core technologies [21][26]. - The establishment of a complete industrial ecosystem, including the development of domestic photolithography machines, is crucial for the long-term success of China's photoresist industry [26][29].
