Chipmaking

China reports a breakthrough in mass-producing immersion DUV chipmaking tools, prompting investor concern. While this poses a potential challenge to ASML’s dominance, experts suggest its impact may be limited to lower-end chips. Key hurdles for China include achieving yield parity and scaling production, areas where ASML holds a significant advantage due to decades of refinement and deployment, particularly in advanced EUV lithography.

Apple is investing over $30 billion in Broadcom to boost U.S. chipmaking, marking its largest domestic manufacturing commitment. This deal aims to produce over 15 billion U.S.-made chips, including custom ASICs for AI and connectivity features. The partnership, extending through 2031, is a key part of Apple’s $600 billion U.S. investment plan, strengthening domestic production and industrial resilience.

ASML’s stock dropped following proposed U.S. legislation aimed at further restricting China’s access to advanced chipmaking technology. The MATCH Act seeks to ban exports of ASML’s Deep Ultraviolet (DUV) lithography machines, vital for China’s semiconductor industry beyond the most cutting-edge nodes. While China has fostered domestic innovation, its reliance on ASML’s DUV tools for foundational chip manufacturing remains significant, potentially disrupting its industry if the bill passes.

Applied Materials (AMAT) introduced new chipmaking systems on Oct 7, 2025, designed to enhance AI chip performance. These include the Kinex™ bonding system for advanced logic and memory, the Xtera™ Epi system for Gate-All-Around transistors, and the PROVision™ 10 eBeam metrology system for improved yield in 3D chips. These innovations address critical areas like logic, DRAM, and advanced packaging, aiming to deliver performance and power-efficiency improvements needed to scale AI.

TSMC maintains that its advanced chipmaking roadmap, including the 1.4-nanometer (A14) process, doesn’t currently require High-NA EUV lithography. The company is prioritizing optimizing their existing EUV technology, achieving significant performance improvements using innovative designs like their second-generation nanosheet GAA, delaying the need for the costly high-NA systems. This strategy highlights TSMC’s focus on cost-effectiveness and technological innovation.
