TSMC plans 1nm roadmap

Taiwan Semiconductor Manufacturing Co. is planning beyond its 2-nanometer rollout and has begun laying out a path toward 1-nanometer-class manufacturing, according to a TechNode report published on May 19. The same report said TSMC is considering up to 12 additional wafer fabs to support nodes from 2nm down to 1.4nm and beyond. That comes as Europe is debating a different question: whether the next phase of industrial policy should focus less on matching Asia’s manufacturing scale and more on building AI chip design companies. Patrick Vandenameele, who took over as chief executive of Belgian research group imec in April, said on May 19 that Europe should use the coming Chips Act 2.0 to strengthen design capabilities and build on existing strengths in semiconductor equipment and research. Reuters reported that Vandenameele said Europe should aim to create home-grown AI chip design firms and warned that failing to produce “the Nvidias of the future” would be a problem for the region. ### Why is TSMC talking about 1nm before 2nm is fully in the market? TSMC’s first 2nm chips are expected to enter production later in 2026, according to TechNode’s May 19 report. The company is already planning the next steps because advanced-node development now runs on multi-year lead times that include process research, fab construction, tool installation and customer design work. TechNode said the additional fabs under consideration would serve future demand across several generations of advanced manufacturing. (technode.com) A separate TechNode report from April 29 said TSMC was targeting a record five-fab 2nm ramp in 2026 and that senior vice president Hou Yongqing had described the expansion pace as the fastest in the company’s history. That report said five 2nm fabs were set to enter ramp-up to mass production in 2026. (technode.com) ### What is Europe arguing about instead of simply building more fabs? Patrick Vandenameele said Europe should not define success only by attracting more front-line manufacturing, according to Reuters and Economic Times coverage published on May 19 and May 20. He said the region’s strengths lie in equipment, research and design, and that Chips Act 2.0 should help create European AI chip companies rather than only subsidize fabrication scale. (technode.com) Reuters reported that he also suggested encouraging TSMC to expand in Dresden for advanced manufacturing where that fits Europe’s industrial base. Imec is already central to that design push. In April 2025, imec said it was coordinating the EU Chips Design Platform, a consortium-backed effort to give startups and smaller chip companies access to design infrastructure, training and capital under the existing European Chips Act. That gives Vandenameele’s comments a concrete policy backdrop rather than a stand-alone appeal. (wtaq.com) ### Where do these two developments meet? The common thread is time. TSMC’s 1nm planning shows that leading-edge manufacturing decisions are being made years before revenue arrives, while Europe’s debate over Chips Act 2.0 centers on whether it can create companies that will still matter when those future nodes are ready. For chip suppliers and their sales teams, that changes how opportunities are counted. Near-term revenue still sits in current-node production and signed capacity, but long-dated design-ins around AI accelerators, CPUs and system architectures now need to be tracked separately from business that can close in the next few quarters. (imec-int.com) That is an inference from the timing of TSMC’s roadmap and Europe’s design-policy push, rather than a statement either party made directly. ### What should readers watch next? TSMC’s next visible milestone is the 2nm production ramp later in 2026, which will show how quickly demand converts into volume output. In Europe, the next marker is the European Commission’s Chips Act 2.0 package, where proposals around design support, equipment strengths and advanced manufacturing incentives are expected to take shape with input from groups including imec.
