What is FINFET?
· Finfet: 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, forming a double gate structure. These devices have been given the generic name "finfets" because the source/drain region forms fins on the silicon surface. The FinFET devices have significantly faster switching times and higher current density than planar CMOS (complementary metal-oxide-semiconductor) technology. FinFET is a type of non-planar transistor or "3D" transistor. It is the basis for modern nanoelectronic semiconductor device fabrication . Microchips utilizing FinFET gates first became commercialized in the first half of the 2010s and became the dominant gate design at 14 nm , 10 nm , and 7 nm process nodes . It is common for a single FinFET transistor to contain several fins, arranged side by si
