TSMC’s 1.4nm production node is officially called A14
Recently, Taiwan Semiconductor Manufacturing Company (TSMC) disclosed at the IEEE International Electron Devices Meeting (IEDM 2023) that the development of its 1.4nm process node is fully underway and progressing smoothly. Additionally, TSMC reemphasized its commitment to achieving mass production of the next-generation 2nm process node by 2025.
According to a report by Tom’s Hardware, this marks TSMC’s first public disclosure about its 1.4nm process node, officially named “A14.” The specific details and timeline for the mass production of the A14 process remain unclear. Based on TSMC’s schedule, the N2 process is slated for mass production by the end of 2025, and the N2P process by the end of 2026. It is reasonable to speculate that the A14 process could be launched between 2027 and 2028.
While TSMC is exploring next-generation stacked CFET transistor technology, it’s unlikely that the A14 process will utilize it. Instead, it may rely on second or third-generation Gate-all-around FETs (GAAFET) transistor technology, similar to the N2 process. It is also uncertain whether TSMC will implement High-NA EUV lithography machines in the A14 process. The introduction of new equipment may pose fresh challenges for chip designers and manufacturers. Cutting-edge semiconductor processes like N2 and A14 require system-level synergistic optimization to truly be effective and elevate performance, power efficiency, and functionality to new heights.
Last year, Samsung unveiled its future technology roadmap at the “Samsung Foundry Forum 2022,” announcing that its SF1.4 (1.4nm level) process is expected to be in mass production by 2027. The number of nanosheets is planned to increase from three to four, likely significantly enhancing performance and power efficiency. From a timing perspective, TSMC’s A14 process should be roughly concurrent with Samsung’s SF1.4 process.
Regarding the widespread rumors of Samsung adopting a price-cutting strategy to secure orders in the 2nm segment, TSMC’s Chairman Mark Liu commented, “Customers still prioritize the quality of technology,” suggesting a high level of confidence in the next-generation processes.
