At IEDM 2019, TSMC revealed two versions of 5 nm, a DUV version with a 5.5-track cell, and an (official) EUV version with a 6-track cell. [24] [25] In December 2019, TSMC announced an average yield of approximately 80%, with a peak yield per wafer of over 90% for their "5 nm" test chips with a die size of 17.92 mm 2. [26]

A double-gate FinFET device. A fin field-effect transistor (FinFET) is a multigate device, a MOSFET (metal–oxide–semiconductor field-effect transistor) built on a substrate where the gate is placed on two, three, or four sides of the channel or wrapped around the channel (gate all around), forming a double or even multi gate structure.
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.. 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 gate voltages scaled down with transistor size, the room for gate voltage swing below the threshold voltage drastically reduced, and the subthreshold conduction became a significant part of the off-state leakage of a transistor. [4] [5] For a technology generation with threshold voltage of 0.2 V, subthreshold conduction, along with other ...
In 1998, the team developed the first N-channel FinFETs and successfully fabricated devices down to a 17 nm process. The following year, they developed the first P-channel FinFETs. [12] They coined the term "FinFET" (fin field-effect transistor) in a December 2000 paper. [13] In current usage the term FinFET has a less precise definition.
On February 18, 2011, Intel announced that it would construct a new $5 billion semiconductor fabrication plant in Arizona, designed to manufacture chips using the "14 nm" manufacturing processes and leading-edge 300 mm wafers. [12] [13] The new fabrication plant was to be named Fab 42, and construction was meant to start in the middle of 2011 ...
As channel length is reduced, the effects of DIBL in the subthreshold region (weak inversion) show up initially as a simple translation of the subthreshold current vs. gate bias curve with change in drain-voltage, which can be modeled as a simple change in threshold voltage with drain bias. However, at shorter lengths the slope of the current ...
