TSMC reportedly targets four 1.4nm plants by Q2 2028

TSMC is reportedly planning a major expansion for its 1.4nm process, with four fabrication plants said to be operational by Q2 2028.

The reported plan comes as TSMC’s 2nm “N2” and “N2P” nodes pick up steam. The company is said to be preparing to move toward a sub-2nm process for the first time, making 1.4nm a major step in its roadmap.

The report describes the company’s ambitions as extensive because they involve a total of four fabrication plants. However, the timeline and construction plans have not been presented as confirmed by TSMC.

Another notable part of the report is its estimate for wafer pricing. A 1.4nm wafer is said to cost only marginally more than a wafer based on the 2nm node. The comparison is described as surprising, and the report cautions that the figures could be incorrect.

No confirmed price is provided in the supplied report. The information remains attributed to Wccftech’s report and should be treated as unconfirmed until TSMC comments on its 1.4nm plans, the four-plant schedule, or the estimated wafer costs.
