Core Viewpoint - The recent lifting of restrictions on Siemens' sale of chip design software to China highlights the fragility of the global semiconductor supply chain and opens a strategic window for Chinese chip companies [1][6]. Event Recap: From Ban to Lifting - On May 28, 2025, the U.S. Department of Commerce issued a ban on three major EDA companies, including Siemens, Cadence, and Synopsys, which collectively hold 74% of the global EDA market share, due to escalating tensions over rare earth trade [5]. - A turning point occurred during talks in London in June, where the U.S. agreed to lift restrictions on chip design software in exchange for China accelerating rare earth export approvals [6]. Strategic Decoding: The 90-Day Window - The policy relaxation is framed as a "technical assessment period," indicating a tactical concession by the U.S. under pressure from rare earth supply issues [10]. - The 90-day window is seen as a critical period for urgent procurement, with 67% of IC design companies planning to maintain a dual-track strategy of using both international EDA tools and domestic alternatives [10]. - Domestic EDA companies like Geke Electronics and Huada Jiutian have some replacement capabilities, but there remains a generational gap in high-end chip design processes compared to international giants [10]. Historical Reflection: Survival Rules for Chinese Enterprises - Huawei's significant R&D investment post-entity list inclusion serves as a model for resilience, with over 400 billion yuan invested over five years, leading to a transformation of its semiconductor arm [11]. - Longsys has successfully reduced its reliance on U.S. technology in its NAND flash production line to below 15% by diversifying its supply chain [11]. Action Guidelines for the Window Period - Chip companies are advised to establish structured response strategies, prioritizing the procurement of essential high-end tools while planning for a phased approach to technology transition [12]. - A three-stage plan is recommended: 90 days for urgent procurement, 180 days for technology transition, and 365 days for self-replacement [12]. - Most companies prefer a dual-track strategy, balancing short-term survival with long-term development, as full EDA autonomy is projected to take 3-5 years [12]. Long-Term Considerations: Reflections Post-Lifting - The limitations of the current lifting of restrictions are notable, as the U.S. retains the right to adjust policies, and the positions of Cadence and Synopsys remain unclear [13]. - The experience underscores the need for the Chinese semiconductor industry to build a resilient innovation system, leveraging the current window of opportunity while maintaining a commitment to independent R&D [13].

Core Viewpoint - The article discusses the challenges and potential solutions related to high numerical aperture (NA) EUV lithography, particularly focusing on the issues of mask stitching and the implications of larger mask sizes on manufacturing efficiency and yield [1][2][9]. Group 1: Challenges of High NA EUV Lithography - The transition to high NA (0.55) EUV lithography presents significant challenges in circuit stitching between exposure fields, impacting design, yield, and manufacturability [1][2]. - The use of deformable optics in high NA systems reduces the exposure area of standard 6×6 inch masks by half, complicating the alignment and yield of critical layers [2][3]. - Misalignment at the stitching boundaries can lead to significant errors in critical dimensions, with a 2nm misalignment potentially causing at least a 10% error in pattern dimensions [2][3]. Group 2: Impact on Yield and Performance - The reliance on precise calibration in advanced lithography is crucial to avoid interference between features across different masks, which can lead to yield issues [3][4]. - The introduction of stitching-aware design strategies is necessary to mitigate performance degradation, with potential frequency reductions of up to 3% and increased power consumption by 3% in worst-case scenarios [5][6]. - Optimizations in design can reduce the impact of stitching on performance, with some strategies achieving a reduction in stitching area loss to below 0.5% and performance degradation to around 0.2% [6][8]. Group 3: Solutions and Industry Perspectives - Increasing the mask size to 6×11 inches could eliminate stitching issues and improve throughput, although it would significantly increase equipment costs and require extensive changes to existing manufacturing infrastructure [9][10]. - The production of larger masks poses additional challenges in stress management and defect control, which are already critical in EUV mask fabrication [10][11]. - Despite the technical advantages of larger masks, industry skepticism remains regarding the associated costs and the need for upgrades to meet future technology nodes [11].
