Gate-all-around FET (GAAFET) is a device with gates on all four sides of the channel. It is a silicon nanowire surrounded by a gate. InGaAs or other III-V materials are used in the channels of some gate-all-around FETs.

The market worth of gate all around FET technology in 2021 was worth USD 30.06 million, and by 2030 it will be worth USD 472.25 million at a 35.8% CAGR during the forecast period.

GAA FETs can overcome FINFET technology’s shortcomings, including a reduction in energy loss and an improvement in durability and efficiency; demand for GAA FETs is growing. As some of the shortcomings of FINFET technology have been successfully address by GAA FETs, it is anticipate that GAA FETs will eventually become a significant rival to FINFET.

Market Dynamics


Compared to FINFETs, GAAFETs are drastically different in their design. Gate material encloses the channel segment on all sides. The design structure enables a transistor design that is significantly more energy-efficient, leading to a significant performance per watt improvement over a 5 nm FINFET technology. As a result, GAAFETs are more effective and durable than FINFETs in terms of performance. According to Semiconductor Engineering, GAA FETs performance will boost by 25% while reducing power consumption by 50%. With finFETs, both figures fell between 15% and 20%. This factor is the main force behind the expansion of the GAAFET technology market.


The GAAFET Technology market’s growth rate is hamper by high nanosheet transistor (nanosheet FET) fabrication costs and performance problems like current breakdown and leakage.


The GAA FET market has grown due to the increasing need for nanotechnology. GAAFETs are available in a variety of sizes and geometries, including hexagonal, nanosheet, nanowire, nano rings, and nano slab. This idea is based on nanotechnology and claims to fit 30 billion transistors using GAA FET technology on a 50 mm2 device.
