DigiTimes places TSMC as having announced to its investors that exploratory studies and R&D for the development of the 2 nm process node have commenced. As today's leading semiconductor fabrication company, TSMC doesn't seem to be one resting on its laurels. Their 7 nm process and derivatives have already achieved a 30% weight on the company's semiconductor orders, and their 5 nm node (which will include EUV litography) is set to hit HVM (High Volume Manufacturing) in Q2 of this year. Apart from that, not much more is known on 2 nm.
After 5 nm, which is expected to boats of an 84-87% transistor density gain over the current 7nm node, the plans are to go 3nm, with TSMC expecting that node to hit mass production come 2022. Interestingly, TSMC is planning to still use FinFET technology for its 3 nm manufacturing node, though in a new GAAFET (gate-all-around field-effect transistor) technology. TSMC's plans to deploy FinFET in under 5nm manufacturing is something that many industry analysts and specialist thought extremely difficult to achieve, with expectations for these sub-5nm nodes to require more exotic materials and transistor designs than TSMC's apparent plans
