Recent media reports suggest that Taiwan Semiconductor Manufacturing Company (TSMC) plans to produce 4-nanometer chips at its second semiconductor fabrication plant in Kumamoto, Japan. If confirmed, this move would mark a significant step toward more advanced manufacturing capabilities for TSMC’s Japanese operations.TSMC announced in 2021 a partnership with Japanese companies Sony and Denso to build its first Japanese fab (JASM) in Kumamoto, focusing on mature-node technologies such as 22/28nm and 12nm, with mass production expected by the end of 2024. The second fab is currently in the planning phase, and sources indicate it may adopt the more advanced 4nm process to meet growing global and domestic demand for high-performance semiconductors.The 4nm node is one of TSMC’s leading-edge process technologies, widely used in smartphones, artificial intelligence, and high-performance computing applications. This expansion not only bolsters Japan’s efforts to strengthen its domestic semiconductor supply chain but also aligns with TSMC’s broader strategy of geographic diversification.However, the final decision on implementing 4nm technology will depend on factors such as market demand, return on investment, and Japanese government subsidies. If approved, the new facility could begin operations around 2027, further solidifying TSMC’s dominance in the global foundry market.
近日，有媒体报道称，台积电（TSMC）计划在其位于日本熊本县的第二座晶圆厂中生产4纳米制程芯片。这一消息若属实，将标志着台积电在日本的半导体制造布局迈入更先进工艺阶段。台积电于2021年宣布与索尼、电装等日本企业合作，在熊本建设首座日本晶圆厂（JASM），主要生产12纳米和22/28纳米成熟制程芯片，预计2024年底开始量产。而第二座工厂目前处于规划阶段，据知情人士透露，该厂可能引入更先进的4纳米技术，以满足日本及全球客户对高性能芯片日益增长的需求。4纳米工艺属于台积电当前主流的先进制程之一，广泛应用于智能手机、人工智能、高性能计算等领域。此举不仅有助于提升日本本土半导体供应链的自主能力，也反映了台积电在全球产能多元化战略下的持续扩张。不过，是否最终采用4纳米制程仍需视市场需求、投资回报及日本政府补贴政策等因素而定。若顺利推进，该工厂有望在2027年前后投产，进一步巩固台积电在全球代工市场的领先地位。
