Computing FinFET Transistor Width
Width of transistor is denoted by w , w plays a crucial role in determining the current flowing through transistor , short – channel effect . width is also used to determine aspect ratio(w/l) which decide the design rule of transistor . For a double gate finFET w is equals to twice of FinFET effective height.
Here,
L= length of gate
T= thickness of Fin
H=height of fin
w= 2(H) for digate FinFET
w=(2(H)+T ) for trigate FinFET
FinFET
Semiconductor Industry is a very dynamic industry as it changes from time to time. As per Moore’s Law, the number of transistors present in a chip doubles every 18 months or 2 years. So the size of chips and electronic device get smaller and smaller. The introduction of FinFET technology in the semiconductor industry played a crucial role.
FinFET is a non-planar transistor that has replaced common planar MOSFET. The Introduction of FinFET not only overcame the challenges of common MOSFET but also helped to make the size of the electronic device compact due to its 3D and fin-shaped vertical structure. FinFET has been widely used in mobile, laptops, and IoT devices due to energy efficiency, fast switching speed, and various such advantages.
