Hello ppl

Could any one please tell me the main differences between MOSFET and FINFET? Advantages of FINFET over mosfet? And is FINFET called as the Trigate ???

Thanks in advance

In my opinion, the main difference is FINFET is a SOI device.
 
FinFETs possess the following key advantages over bulk MOSFETs: reduced leakage,excellent subthreshold slope,
and better voltage gain without degradation of noise or linearity. This makes them attractive for digital and low-frequency RF applications around 5 GHz, wherethe performance-power tradeoff is important. On the other hand,in high-frequency applications, planar bulk MOSFETs are seento hold the advantage over FinFETs due to their higher peak transconductance. However, this comes at a cost of a reducedvoltage gain of bulk MOSFETs.
