Key Takeaways
Taiwan Semiconductor Manufacturing Co. is extending its semiconductor process roadmap to the sub-1-nanometer scale, planning trial production for 2029 in a move that could secure its manufacturing leadership against rivals like Samsung and Intel for the next decade.
The plan, reported by DigiTimes, provides a clear timeline for the world’s largest chip foundry and its primary customer, Apple Inc. "This roadmap keeps TSMC two to three years ahead of competitors and ensures Apple’s iPhone and Mac processors remain at the leading edge of performance and power efficiency," an industry analyst said.
The roadmap details a two-step advancement. First, TSMC's 1.4-nanometer process, codenamed A14, is slated for mass production in 2028, offering a performance and efficiency improvement of up to 30%. Following that, the first sub-1nm process will enter trial production in 2029 with an initial target of 5,000 wafers per month.
For investors, this aggressive schedule solidifies TSMC’s revenue pipeline and justifies its high capital expenditures. It ensures that Apple, which accounts for over 25% of TSMC's revenue, remains a locked-in partner, reducing the risk of it diversifying to other foundries for its most critical processors.
TSMC's technical path is clearly defined for the remainder of the decade. The company is currently focused on ramping up its 2-nanometer production to meet demand for Apple's upcoming iPhone 18, which is expected to feature chips using the new node.
Following the 2nm ramp, the foundry has already secured orders for its A16 process (1.6-nanometer). The subsequent A14 (1.4-nanometer) node represents a major milestone for 2028, promising significant power and performance gains that are critical for both mobile devices and data center AI accelerators. The move to sub-1nm production—a scale often referred to in angstroms—represents the largest technical challenge on the horizon.
To facilitate the initial sub-1nm trials, TSMC plans to utilize its A10 facility in Tainan, Taiwan, coordinating operations across four factories (P1 to P4) to meet the monthly output goal of 5,000 wafers.
This expansion comes as the company is already facing capacity constraints due to the explosive demand for AI chips from companies like Nvidia and AMD. By providing a long-term roadmap, TSMC can secure advance orders and commitments from key clients like Apple, who have previously paid premiums to secure initial wafer batches.
While the roadmap is ambitious, its success hinges on solving the immense challenge of manufacturing yield. Achieving stable, high-volume production on such a microscopic scale is a significant hurdle.
There are already rumors in the smartphone industry that poor yields on the most advanced nodes are forcing some manufacturers to reserve the best chips for their highest-end "Ultra" models. If this trend continues, it could mean that only premium-priced devices will feature the latest processor technology, altering product strategies across the industry and increasing the cost for consumers wanting the latest performance. For TSMC, managing yield will be the critical factor in determining the profitability of these next-generation nodes.
