The world's largest foundry, Taiwan Semiconductor Manufacturing Company (TSMC), is set to accelerate its 1.4-nanometer production process, with mass production expected to begin as early as the second half of next year.


According to the Central Taiwan Science Park Administration, TSMC's construction of its 1.4-nanometer plant in Taichung is progressing rapidly. The first plant (P1) has completed its steel structure work and is slated to begin test operations in April 2027, allowing for mass production to commence shortly thereafter, significantly ahead of the previously scheduled 2028 timeline.


TSMC has also applied to establish two temporary offices at the site, which are expected to be completed alongside the plant in April. Initially, around 5,400 employees for operations and outsourcing are anticipated to occupy these offices.


Additionally, the second plant (P2) is also ahead of schedule and is expected to be completed by October 2027. The third plant (P3) has already received construction approval, while the fourth plant (P4) is currently in the process of obtaining its permit. The administration plans to construct all four plants approximately six months apart, targeting completion of P3 in the second quarter of 2028 and P4 in the fourth quarter of the same year.


According to the administration, once all four plants are operational by 2028, the total workforce is expected to reach between 9,000 and 10,000, with annual revenue projected at around NT$500 billion (approximately US$21.2 billion). However, the administration noted that the actual revenue figures will be determined once production capacity is finalized, suggesting that the NT$500 billion estimate could be conservative based on current production costs and market demand.
