2nm争霸战，已打响

Core Viewpoint - TSMC and Samsung are set to produce the industry's most advanced 2nm chips in the second half of this year, with TSMC having a competitive edge due to higher yield rates compared to Samsung [1][2]. Group 1: TSMC's 2nm Process - TSMC has begun receiving orders for its 2nm process and plans to produce these chips at its Hsinchu and Kaohsiung facilities, utilizing GAA architecture which is expected to improve performance by 10% to 15% and reduce power consumption by 25% to 30% [1][4]. - Major clients for TSMC's 2nm chips include Apple, Nvidia, AMD, Qualcomm, and MediaTek, with MediaTek's CEO hinting at a product design completion by September [1][4]. - TSMC's 2nm defect density has reportedly surpassed that of its 5nm and even 7nm and 3nm processes, indicating a high level of technological maturity [4][5]. Group 2: Samsung's 2nm Process - Samsung aims to start producing 2nm chips in the second half of the year, likely for its Galaxy S26's Exynos 2600 processor, but faces challenges with a lower yield rate of approximately 40% compared to TSMC's 60% [2][1]. - Samsung is leveraging its previous experience with GAA architecture from its 3nm production to improve the yield of its 2nm chips [2]. Group 3: Production Capacity and Future Plans - TSMC's 2nm process is entering trial production, with plans to ramp up to a monthly capacity of 30,000 wafers by the end of 2025, and potentially expand to 120,000 to 130,000 wafers by 2027 [5]. - TSMC is investing over 1.5 trillion NTD to expand its facilities in Hsinchu and Kaohsiung, aiming to create the world's largest semiconductor manufacturing hub [5].
