Core Viewpoint - Taiwan's tightening of export controls on certain high-tech products is accelerating the push for self-sufficiency in the semiconductor supply chain, particularly in the area of ABF substrates [1][2]. Group 1: Export Control Measures - Taiwan's International Trade Administration has added entities such as SMIC and Huawei to a restricted export list, requiring permits for exports to these entities [1]. - A total of 601 entities, including those from Russia, Pakistan, Iran, Myanmar, and mainland China, have been added to the list due to concerns over military expansion activities [1]. Group 2: Domestic Industry Response - Domestic companies are actively working to support the supply chain, with companies like Xinsong Technology already supplying 20-layer substrates in bulk [2]. - Efforts are ongoing to validate and produce higher-layer substrates, indicating a potential breakthrough in domestic production capabilities [2]. Group 3: Technical Challenges - The ABF substrate segment remains one of the few areas in the Ascend supply chain that is not fully self-sufficient, with Taiwanese manufacturers holding a significant market share [1]. - The technical challenges in producing high-spec ABF substrates include maintaining layer alignment and thickness consistency, especially for larger and multi-layered products [1].
