Zheng Quan Shi Bao Wang·2025-10-27 02:33Core Viewpoint - The significant rise in the photoresist sector is driven by the establishment of China's first EUV photoresist standard and recent breakthroughs in photoresist technology, indicating a positive outlook for the industry [1][2]. Group 1: Market Performance - The photoresist concept saw a substantial increase on the 27th, with companies like Jingrui Electric Materials hitting a 20% limit up, and others such as Canaan Technology and Nanda Optoelectronics rising over 13% [1]. - The market for photoresists in China is projected to grow to over 11.4 billion yuan in 2024 and reach 12.3 billion yuan by 2025 [2]. Group 2: Technological Advancements - A team led by Professor Peng Hailin from Peking University has achieved a breakthrough by using cryo-electron tomography to analyze the micro-3D structure and entanglement behavior of photoresist molecules in a liquid phase, which can guide the development of industrial solutions to reduce photoresist defects [1][2]. - The new standard for EUV photoresists, titled "Testing Methods for Extreme Ultraviolet (EUV) Photoresists," was publicly announced on October 23, with a deadline for comments set for November 22 [1]. Group 3: Industry Implications - The advancements in photoresist technology are expected to benefit the entire semiconductor supply chain, including upstream material suppliers, equipment manufacturers, midstream photoresist producers, and downstream application companies [2].
