A multigate device, multi-gate MOSFET or multi-gate field-effect transistor (MuGFET) refers to a metal–oxide–semiconductor field-effect transistor (MOSFET) that has more than one gate on a single transistor. The multiple gates may be controlled by a single gate electrode, wherein the multiple gate surfaces act electrically as a single gate ...
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.
Multi-gate MOSFET (MuGFET) Multi-gate MOSFET ... Samsung Electronics have begun risk production of 3 nm GAAFET transistors in June of 2022. [136] Apple A17 Pro
Cross-sectional view of a MOSFET type field-effect transistor, showing source, gate and drain terminals, and insulating oxide layer. The field-effect transistor (FET) is a type of transistor that uses an electric field to control the current through a semiconductor. It comes in two types: junction FET (JFET) and metal-oxide-semiconductor FET ...
In 2003, a research team at NEC fabricated the first MOSFETs with a channel length of 3 nm, using the PMOS and NMOS processes. [20] [21] In 2006, a team from the Korea Advanced Institute of Science and Technology (KAIST) and the National Nano Fab Center, developed a 3 nm width multi-gate MOSFET, the world's smallest nanoelectronic device, based on gate-all-around technology.
The transistor models developed and currently maintained by UC Berkeley are: . BSIM-CMG (Common Multi-Gate), [3] BSIM-IMG (Independent Multi-Gate), [4] the only model published without source-code (whose publication is foreseen for July 13, 2021)
It is based on FinFET (fin field-effect transistor) technology, a type of multi-gate MOSFET technology. As of 2021, the IRDS Lithography standard gives a table of dimensions for the "7 nm" node, [1] with examples given below:
Multi-gate field-effect transistor (MuGFET) Fin field-effect transistor (FinFET), source/drain region shapes fins on the silicon surface GAAFET, Similar to FinFET but nanowires are used instead of fins, the nanowires are stacked vertically and are surrounded on 4 sides by the gate
