China has started a battle against the US and Japan that no one is talking about. And it is crucial to win the chip war

China has initiated a strategic push to break Japan's long-standing monopoly in the critical photoresist materials sector, a move that could significantly alter the global semiconductor landscape. This development is crucial for China's ambition of achieving total independence in its chip manufacturing industry, a goal it aims to accomplish within the next five years. Photoresists are indispensable advanced materials used in photolithography, the process by which circuit patterns are precisely transferred to silicon wafers. JSR Corporation, a Japanese firm, currently holds a dominant position in supplying these essential liquids to leading chip manufacturers, underpinning Japan's expertise in advanced materials for integrated circuits. China's targeted effort to develop its own high-quality photoresists signifies a direct challenge to this established dominance. This escalating competition in the semiconductor supply chain has broad implications for global tech powers, particularly the United States and its allies who have sought to limit China's access to advanced chip technology. The success of China's endeavor could reduce reliance on Japanese suppliers and reshape the geopolitical balance in the high-stakes semiconductor war, impacting everything from consumer electronics to advanced AI applications.
