In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node. As of 2021[update], TSMC and Intel both have planned 2 nm products on their roadmaps, with TSMC scheduling earliest production for 2023 and Intel for 2024.
Background
In late 2018, TSMC chairman Mark Liu predicted chip scaling would continue to 3 nm and 2 nm nodes;[1] however, as of 2019, other semiconductor specialists were undecided as to whether nodes beyond 3 nm could become viable.[2]
TSMC began research on 2 nm in 2019.[3] TSMC expected to transition from FinFET to GAAFET transistor types when moving from 3nm to 2nm.[4] It has been reported that TSMC is expected to enter 2 nm risk production around 2023 or 2024.[5]
Intel's 2019 roadmap scheduled potentially equivalent 3 nm and 2 nm nodes for 2025 and 2027 respectively.[6] In December 2019, Intel announced plans for 1.4 nm production in 2029.[6]
In August 2020, TSMC began building a R&D lab for 2 nm technology in Hsinchu, expected to become partially operational by 2021.[7] In September 2020 (SEMICON Taiwan 2020) it was reported that TSMC Chairman Mark Liu had stated the company would build a plant for the 2 nm node at Hsinchu in Taiwan, and that it could also install production at Taichung dependent on demand.[8]
At the end of 2020, seventeen European Union countries signed a joint declaration to develop their entire semiconductor industry, including developing process nodes as small as 2 nm, as well as designing and manufacturing custom processors, assigning up to 145 billion euro in funds.[9][10]
In May 2021, IBM announced it had produced 2 nm class transistor using three silicon layer nanosheets with a gate length of 12nm.[11][12][13]
In July 2021, Intel unveiled its process node roadmap from 2021 onwards. The company confirmed their 2 nm process node called Intel 20A, with the "A" referring to angstrom, a unit equivalent to 0.1 nanometer.[14] Their new naming scheme aligned their product names to similar designations from their main competitors.[15] Their 2021 roadmap scheduled the Intel 20A node for introduction in 2024.[15]
Beyond 2 nm
Intel have planned 18A (equivalent to 1.8 nm) products for 2025.[14]
