Core Viewpoint - Rapidus, a company supported by the Japanese government, has made significant progress in the trial production of 2-nanometer chips, marking a milestone in Japan's semiconductor revival efforts, although details on product quality and customer attraction remain limited [1][2]. Group 1: Company Progress and Goals - Rapidus announced the successful manufacturing of its first 2-nanometer transistor in Japan, with plans to optimize the manufacturing process further [1]. - The company aims to control the error rate of its products at 50% initially, with a future target of reducing it to 10%-20% [2]. - The trial production of 2-nanometer chips is set to begin in April 2025, with mass production expected by 2027, which would represent Japan's most advanced chip technology to date [3]. Group 2: Government Support and Financial Aspects - The Tokyo government has committed up to 1.7 trillion yen (approximately 110 billion) in support for Rapidus, exceeding the 1.2 trillion yen allocated for TSMC's factories in Kumamoto [4]. - The total project cost is estimated at 5 trillion yen (about 340 billion), raising concerns about the financial burden on taxpayers [4]. - Rapidus plans to raise 200 billion yen in new investments this year from both government and private sectors, although many companies remain cautious due to the project's high risks [4]. Group 3: Competitive Landscape and Challenges - Rapidus faces significant challenges in establishing global competitiveness, as it aims to enter the market during a technological transition and close the gap with larger international firms [4][6]. - Competitors like TSMC, Intel, and Samsung are also advancing in the semiconductor race, with TSMC planning to start mass production of 2-nanometer chips by the end of 2025 [6]. - Japan is experiencing a shortage of semiconductor engineers, with many experienced professionals nearing retirement age, prompting Rapidus to collaborate with IBM and startups like Tenstorrent to address this issue [7]. Group 4: Business Model and Customer Engagement - Rapidus is developing a new business model aimed at small and medium-sized clients, offering faster factory response times and accepting smaller custom chip orders [5]. - The company intends to create an integrated platform that combines manufacturing, packaging, and some design processes, differing from the traditional industry practice of separating these stages [5]. - Early target customers include AI chip startups like Tenstorrent, and Rapidus is in discussions with several companies, including large tech firms in the U.S. [6].
