装光刻胶的瓶子，中国终于造出来了

Core Viewpoint - The article discusses the successful development of specialized glass bottles for photoresist, marking the end of China's 100% reliance on imports for this technology, which is crucial for semiconductor manufacturing [6][27]. Group 1: Importance of Photoresist - Photoresist is essential for the chip manufacturing process, as it allows for the precise etching of circuit patterns onto silicon wafers [8][12]. - The characteristics of photoresist, such as high sensitivity and purity, directly influence the precision of photolithography machines [12]. Group 2: Specialized Glass Bottles - The specialized glass bottles for photoresist are designed to block UV light and maintain the chemical stability of the photoresist inside [18]. - These bottles are made from high-purity borosilicate glass, which minimizes contamination from metal ions, and feature advanced sealing mechanisms to prevent oxidation and hydrolysis [20][21]. Group 3: Challenges in Domestic Production - The production of specialized glass bottles involves high technical barriers, with the top three global manufacturers controlling 75% of the market [23]. - The market for these bottles is limited, and they are closely integrated with photoresist formulations and semiconductor manufacturing processes, creating significant entry barriers for new players [26]. Group 4: Implications of Domestic Production - The domestic production of specialized bottles resolves the issue of "having photoresist but no bottles," providing a stable return expectation for local companies [27]. - This development signifies a positive cycle for China's semiconductor industry, moving from isolated breakthroughs to systemic advancements [28].
