TSMC Lays Down Roadmap For Its 2nm Chips; Will Enter Mass Production In 2025

With TSMC’s 3nm Process to Enter Mass Production in Q3 of 2022, TSMC Has Already Laid Down The Path to Its 2nm Process.

With TSMC all set to start mass-producing its 3nm chips sometime in Q1 of 2023, TSMC has already revealed the future roadmap for its next-generation 2nm chips at its first-quarter earnings call of 2022. The new chips are also expected to feature a new transistor design.

According to a statement made by TSMC’s CEO C.C. Wei, the next generation of chip fabrication process will continue to rely on ASML’s existing extreme ultraviolet (EUV) lithography machines, with a very high NA (numerical aperture) of 0.33.

Furthermore, he added, the new process will be ready for risk/test production sometime in Q4 of 2024 and is scheduled to begin high-volume manufacturing (HVM) toward the end of 2025. Thus, suggesting that TSMC’s first 2nm customer (likely Apple) should receive its first N2-based chips sometime in 2026.

Technically speaking, TSMC’s N2 process is also set to transition from using older FinFET (fin field-effect transistors) in favour of GAA (gate-all-around) transistor technology. The same transistor tech has already been improved upon by Samsung with the introduction of its proprietary MBCFET (Multi-bridge channel FET) design that’s expected to make its way to the upcoming 3nm chips that will hit the markets soon.

That being said, apart from giving us a look at the future roadmap of TSMC’s next-gen 2nm fabrication process, this report also shows how difficult it is to produce more advance and smaller chips as we are nearing the 1nm mark. Previously TSMC used to kick off production using its brand-new nodes every two years. This is not the case with its 2nm process, as it’s expected to enter HVM (High Volume Manufacturing) phase almost four years after its 3nm process entered the HVM phase.

Whatever the case may be, we can’t wait to see what performance and power consumption benifits the next-gen 2nm chips will bring when they finally hit the markets sometime in 2026.
