Classification Of FinFET
FinFET Can be classified as following on the basic of –
- Number of gates
- Type of substrate
Classification Of FinFET on the basis of Number of Gates
On the basis of number of gates FinFET is of two types :
- Shorted gate FinFET (SG FinFET)
- Independent Gate FinFET (IG FinFET)
In shorted gate FinFET their is channel between front and back gate as it is sorted and in Independent gate FinFET their is no channel present between front and back gate both gate work independently ,they are not sorted.
Shorted Gate FinFET |
Independent Gate FinFET |
---|---|
Front and back gate is shorted and connected to each other. |
Front and back gate are not shorted and independent of each other. |
It is 3 terminal device. |
It is 4 terminal device. |
It need less area. |
It need more area. |
We cannot externally control threshold voltage. |

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.
