In August 2022, a consortium of Japanese companies funded a new venture with government support called Rapidus for manufacturing of 2 nm chips. In July 2022, Samsung made a number of disclosures regarding the company's forthcoming process technology called 2GAP ( 2nm Gate All-around Production): the process remains on track for 2025 launch into mass production number of nanosheets will increase from 3 in 3GAP to 4 the company works on several improvements of metallization, namely "single-grain metal" for low-resistance vias and direct-etched metal interconnect planned for 2GAP and beyond. In July 2022, TSMC announced that its N2 process technology will feature backside power delivery and will offer 10–15% higher performance at iso power or 20–30% lower power at iso performance and over 20% higher transistor density compared to N3E. In April 2022, TSMC announced its GAAFET N2 process technology would enter risk production phase at the end of 2024 and production phase in 2025. ![]() In October 2021, at Samsung Foundry Forum 2021, Samsung announced it would start mass production with its MBCFET (multi-bridge channel FET, Samsung's version of GAAFET) 2 nm process in 2025. Their 2021 roadmap scheduled the Intel 20A node for volume production in 2024 and Intel 18A for 2025. Intel's 20A node is projected to be their first to move from FinFET to Gate-All-Around transistors (GAAFET) Intel's version is named ' RibbonFET'. At the same time they introduced a new process node naming scheme that aligned their product names to similar designations from their main competitors. The company confirmed their 2 nm process node called Intel 20A, with the "A" referring to angstrom, a unit equivalent to 0.1 nanometer. In July 2021, Intel unveiled its process node roadmap from 2021 onwards. In May 2021, IBM announced it had produced chips with 2 nm class GAAFET transistors using three silicon layer nanosheets with a gate length of 12 nm. Īt 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. Intel's 2019 roadmap scheduled potentially equivalent 3 nm and 2 nm nodes for 20 respectively, and in December 2019 announced plans for 1.4 nm production in 2029. According to Nikkei the company expects to install production equipment for 2 nm by 2023. According to the Taiwan Economic Daily (2020) expectations were for high yield risk production in late 2023. In September 2020 TSMC confirmed this and stated that it could also install production at Taichung dependent on demand. In August 2020 it began building an R&D lab for 2 nm technology in Hsinchu, expected to become partially operational by 2021. In July 2021, TSMC received governmental approval to build its 2 nm plant. TSMC began research on 2 nm in 2019 -expecting to transition from FinFET to GAAFET transistor type. In late 2018, TSMC chairman Mark Liu predicted chip scaling would continue to 3 nm and 2 nm nodes however, as of 2019, other semiconductor specialists were undecided as to whether nodes beyond 3 nm could become viable. Background īy 2018, a number of transistor architectures had been proposed for eventual replacement of FinFET, most of which are based on the concept of GAAFET: horizontal and vertical nanowires, horizontal nanosheet transistors (Samsung MBCFET, Intel Nanoribbon), vertical FET (VFET), complementary FET (CFET), stacked FET, and negative-capacitance FET (NC-FET) which uses drastically different materials. As such, "2 nm" is used primarily as a marketing term by the semiconductor industry to refer to a new, improved generation of chips in terms of increased transistor density (a higher degree of miniaturization), increased speed, and reduced power consumption compared to the previous 3 nm node generation. According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems published by the Institute of Electrical and Electronics Engineers (IEEE), a "2.1 nm node range label" is expected to have a contacted gate pitch of 45 nanometers and a tightest metal pitch of 20 nanometers. The term "2 nanometer" or alternatively "20 angstrom" (a term used by Intel) has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. As of May 2022, TSMC plans to begin risk 2 nm production at the end of 2024 and mass production in 2025 Intel forecasts production in 2024, and South Korean chipmaker Samsung in 2025. 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.
