Rapidus and HCLTech Partner to Accelerate Japan's 2nm Chip Ambitions, IBM Backs Chitose Plant
The global semiconductor industry's next node war has a new front: Japan and India are deepening collaboration on advanced manufacturing, with Rapidus — Japan's answer to TSMC — teaming up with HCLTech to build chip engineering centers in India, while International Business Machines Corp. (IBM) simultaneously announced it will establish a presence at the Chitose site hosting Rapidus' 2nm fab. Both moves, announced within days of each other in late October 2026, signal a coordinated push to accelerate 2nm-class production by 2027 and reshape the geopolitics of advanced logic manufacturing.
India Engineering Centers Form Core of Rapidus-HCLTech Alliance
On October 26, 2026, Rapidus and HCLTech confirmed a strategic business partnership to expand dedicated manufacturing facilities for advanced semiconductor technologies. The agreement calls for HCLTech to operate engineering design and validation centers at Rapidus' existing facilities, leveraging HCLTech's expertise in design services, test, and yield enhancement for AI accelerator and automotive compute chips. Chief Executive Atsuyoshi Koike of Rapidus framed the partnership as essential to de-risk lead times that have stretched to eight months for CoWoS advanced packaging as AI chip demand accelerates.
"This partnership combines Rapidus' manufacturing roadmap with HCLTech's design and test leadership," Koike said in the company's official release. "Together we can compress development cycles and deliver 2nm-class volume production on schedule."
The venture said on Monday it would partner with 17 companies globally, including US chip design software firm Synopsys and India's Infosys, to help customers design chips. Rapidus needs to secure customers ahead of the planned launch of 2-nanometre contract chip production in the second half of the next fiscal year, a project that Prime Minister Sanae Takaichi is counting on to rebuild Japan's semiconductor industry.
"The biggest question for Rapidus is still who will actually fill the fab," said Nori Chiou, investment director at White Oak Capital. Monday's announcement was "not yet evidence of commercial traction," he said, but showed incremental progress.
It also faces technological and competitive hurdles as it looks to make 2-nm chips, which offer faster, more energy-efficient performance than earlier generation chips, at its fabrication plant. The unprecedented AI investment boom has fueled demand for semiconductors and computing infrastructure, a trend Rapidus hopes to capitalise on. It is up against Taiwan's TSMC, which spent decades refining its processes and dominates leading-edge chipmaking, South Korea's Samsung Electronics, which began producing 2-nm chips last year, and Intel, which is expanding its own advanced capacity in response.
"TSMC will continue to dominate the majority of the market. But there are plenty of customers in the remaining 20% who cannot get capacity from TSMC because they are low on its priority list or their orders are small," said Akira Minamikawa, an analyst at Omdia. Rapidus CEO expressed confidence there is enough market demand to support an additional leading-edge manufacturer. "One or two companies are nowhere near enough," Koike told Reuters.
Some potential customers remain cautious. "We're already having TSMC make our chips, so we can't switch everything to Rapidus. If it didn't work out, we couldn't go back to TSMC, so we have to be cautious," said one executive who declined to be identified because the deliberations are private. Customers may use Rapidus to diversify supply chains, while the presence of a leading-edge manufacturer could also benefit Japan's materials and equipment makers.
Japan's global semiconductor market share has fallen from about 50% in the 1980s to less than 10% today. Chipmakers operating in Japan include memory producer Kioxia and TSMC, which has partnered with Sony. Other government-backed initiatives include Noetra, which is developing a foundational model for physical AI and robotics.
IBM's Chitose Investment Anchors the 2nm Ecosystem
Two days later, on October 27, 2026, IBM confirmed it will establish a design and research center at the Rapidus campus in Chitose, Hokkaido — the same site where Rapidus is building its 2nm fabrication plant, targeted for mass production in 2027. The Japan Times reported that IBM's move is part of a broader Japanese government initiative to attract foreign chip-design talent to the country, offering subsidies and streamlined regulatory approvals for foreign semiconductor firms.
IBM will focus on analog and mixed-signal design for power-management integrated circuits, a niche where the company holds deep patents but has seen declining domestic capacity as U.S. foundries consolidated. The Chitose facility will also host joint development work on silicon photonics for data-center interconnects, aligning with both IBM's roadmap and Rapidus' need for high-speed I/O solutions for AI accelerators.
"IBM's presence at Chitose strengthens the entire ecosystem," said a Japanese Ministry of Economy, Trade and Industry (METI) official, who spoke on condition of anonymity. "Having a global design leader like IBM in the same precinct as a new 2nm foundry creates synergies in test, packaging, and talent development that are impossible to replicate in isolation."
The Japanese government has set a target of 2nm mass production at Rapidus by 2027, with an estimated $6.5 billion in public funding committed to the project since 2023. IBM's design center is not a fabrication investment — IBM does not operate leading-edge fabs — but the company's expertise in process design kits (PDKs) and test infrastructure will help Rapidus validate 2nm device performance earlier in the development cycle.
Geopolitics and the New Japan-India Axis
The Rapidus-HCLTech partnership and IBM's Chitose center are inseparable from the shifting geopolitics of semiconductor supply chains. China's rapid capacity expansion — adding 14 percent to its wafer output this year, reaching 10.1 million wafers per month according to SEMI — has prompted both Japan and the United States to court alternative manufacturing hubs. The United States passed the CHIPS and Science Act in 2022, committing $52.7 billion in federal subsidies for domestic semiconductor research and fabrication. The European Union's Chips Act, adopted in 2023, commits €43 billion ($46 billion) to similar ends.
Against this backdrop, the Japan-India chip alliance represents a deliberate diversification strategy. HCLTech, India's largest IT services firm by revenue, brings 180,000 engineers and a growing portfolio of semiconductor design services. Rapidus, backed by Japanese state capital and partnerships with IBM, Intel, and now HCLTech, offers an alternative to Taiwan-centric manufacturing. The confluence of these investments — Japanese public funding, Indian engineering talent, and U.S. big-tech capital — illustrates how the 2nm node has become a geopolitical flashpoint as much as a technical milestone.
For end customers, the implications are direct. AI accelerator lead times have grown from under 3 months in 2023 to over 8 months in 2026, driven by CoWoS packaging constraints and limited 2nm/3nm fab capacity. If Rapidus can achieve 2nm volume production by 2027 as targeted, it would add a fourth major source of leading-edge logic alongside TSMC, Samsung, and Intel — a meaningful supply diversification for data-center operators and automotive OEMs whose roadmaps depend on 2nm/3nm chips for next-generation AI and autonomous-vehicle platforms.
Conclusion
The October 2026 announcements from Rapidus, HCLTech, and IBM mark the most significant single-period expansion of advanced semiconductor design and manufacturing capacity outside East Asia's traditional hubs. While challenges remain — Rapidus' first 2nm chips will enter low-volume production in 2026, with full mass production targeted for 2027, and the company will need to overcome yield learning curves that have stalled many new-node entrants — the India-Japan partnership creates a credible counterweight to the Taiwan-centric model that has dominated the industry for two decades.
For investors, the signal is clear: the advanced-node landscape is fragmenting, and the companies that can combine manufacturing capability with design engineering and test infrastructure will capture the most value as AI-driven demand for 2nm/3nm accelerators scales toward $110 billion in annual capital expenditure by 2027. The Japan-India axis may not replace Taiwan's dominance overnight, but it establishes a durable second front for the industry's most advanced technology.
