TSMC is urging customers to apply early for production allocation on its next generation N2 node, as most available capacity has already been reserved until the end of 2027. Lead time is said to be six quarters on what production capacity is left, which is creating significant pressure on companies relying on TSMC to meet their own product roadmaps. Even partners that have secured N2 allocation are described as facing long waits between tape-out and finished silicon.
According to the report, even those lucky enough to have been allocated production on the N2 node are said to be looking at as much as a 12 month lead time from start of production until delivery of the finished chips. These delays are affecting both major and smaller customers, complicating launch schedules and forcing tougher decisions about which designs to prioritize. The tight capacity environment also increases the risk that any schedule slips or design changes could cascade into multi-quarter product delays.
Culpium confirms that NVIDIA is now TSMC’s biggest customer, yet NVIDIA is also said to be affected by the N2 node production constraints, although not as severely as smaller clients. There are limited exceptions to the long lead times through so-called hot lots or hot runs, which are last-minute production slots offered without guaranteed timelines. However, these hot runs come in at premium pricing for the customers, and the combination of elevated costs and extended waits means many planned products are unlikely to move forward because they would either be too expensive to manufacture or take too long to justify the investment.
