Core Viewpoint - Rapidus aims to produce cutting-edge 2-nanometer chips, requiring significant funding and support from the Japanese government and private sector to achieve mass production by 2027 [1][2]. Group 1: Funding and Support - The estimated cost for trial production of 2-nanometer chips is 2 trillion yen, while mass production will require an additional 3 trillion yen [1][2]. - As of now, Rapidus has secured 1.7225 trillion yen in support, including 920 billion yen from 2022 to 2024 and a maximum of 802.5 billion yen from the Ministry of Economy, Trade and Industry (METI) confirmed on March 31 [1][2]. - METI plans to provide subsidies and is discussing a potential investment of 100 billion yen through government agencies, pending legislative approval [2]. Group 2: Production Plans - The trial production line in Hokkaido will officially start with a workforce of 150, aiming to produce the first trial products by early summer [1][2]. - Rapidus has already received over 200 units of advanced extreme ultraviolet (EUV) lithography equipment necessary for semiconductor production [1]. Group 3: Market Strategy and Challenges - Rapidus intends to provide trial product data to customers by mid-July, with a goal of achieving a yield rate of 50% initially, and ultimately reaching 80-90% [2]. - The company recognizes the need for private funding, as current private contributions amount to only 7.3 billion yen from eight companies, including Toyota, NTT, and Sony [2][3]. - There are concerns regarding the risks associated with investing in a company without production experience, leading to cautious funding approaches from potential investors [3].
