这家公司，拯救日本芯片？

Core Viewpoint - The article discusses the ambitious efforts of Rapidus, a Japanese semiconductor company, to re-establish Japan as a leader in advanced chip manufacturing, particularly with the goal of producing 2nm chips by 2027, supported by IBM and significant government funding [1][16]. Group 1: Rapidus and Its Goals - Rapidus was established in 2022 amid rising global demand for semiconductor manufacturing capacity, driven by AI and geopolitical pressures for local production [1]. - The company aims to produce 2nm chips by 2027 and is preparing for nodes beyond 2nm with IBM's support [1]. - Rapidus has achieved several milestones, including a pilot project for a 2nm wafer fab in Hokkaido and partnerships with Siemens, imec, and Tenstorrent [3]. Group 2: Comparison with TSMC - The article highlights the successful model of TSMC, which was founded with a mix of government and private investment, leading to Taiwan's semiconductor rise [2]. - TSMC's model relies on a strong ecosystem of IP suppliers and a self-reinforcing cycle of demand and supply, which Rapidus is struggling to replicate [5][6]. - Analysts estimate that by 2026, Rapidus's wafer production may only reach 25,000 wafers per month, a fraction of TSMC and Samsung's output [6]. Group 3: Financial and Structural Challenges - Rapidus is reportedly providing upfront payments to IP suppliers to secure early support, diverging from TSMC's traditional royalty-based model [3][6]. - The company faces a significant financial burden, needing approximately 5 trillion yen (around 340 to 350 billion USD) for full-scale production, with government subsidies and corporate investments covering the costs [7]. - The reliance on upfront payments raises concerns about long-term sustainability and the potential for a narrow ecosystem of IP suppliers [12][13]. Group 4: Ecosystem Development - Rapidus recognizes that having expensive equipment is not the most challenging aspect of launching advanced nodes; rather, establishing a robust design ecosystem is crucial [9]. - The company aims to differentiate itself by offering faster turnaround times for wafer processing, which could attract customers despite ecosystem challenges [9][14]. - The article draws parallels with GlobalFoundries, which also provided financial incentives to attract IP suppliers but ultimately struggled to maintain a healthy ecosystem [11]. Group 5: Future Outlook - Rapidus's strategy of upfront payments may not guarantee customer adoption or sustainable economic benefits, highlighting the need for a self-sustaining ecosystem [16]. - The success of Rapidus will depend on its ability to convert early arrangements into long-term ecosystem dynamics, contrasting with TSMC's organically grown model [16].
