日本官方否认断供光刻胶，国产化率仍低于20%

Core Viewpoint - The semiconductor industry heavily relies on lithography technology, with a low domestic production rate of lithography machines and photoresists in China, leading to significant dependence on imports, particularly from Japan and the Netherlands [1][3]. Group 1: Dependency on Japanese Supply - Japan's recent statements have clarified that there is no change in trade policy regarding the supply of photoresists to China, alleviating fears of a supply disruption [3]. - Analysts believe that Japan is unlikely to completely halt supplies due to China's current chip manufacturing capabilities, which do not require advanced EUV photoresists that Japan specializes in [5]. - The demand for ArF photoresists in China is limited due to existing manufacturing processes, with a greater need for more mature KrF photoresists, which can be sourced from both South Korea and domestic producers [8]. Group 2: Potential Supply Chain Challenges - Japan may impose barriers such as requiring approvals rather than outright halting supplies, as a complete stop would leave them with no leverage in negotiations [10]. - Despite Japan's denial of supply disruptions, there is a call for China to strengthen its own capabilities to mitigate risks associated with reliance on foreign suppliers [12].
