What are FinFETs used for?

A FinFET is a transistor. Being a transistor, it is an amplifier and a switch. Its applications include home computers, laptops, tablets, smartphones, wearables, high-end networks, automotive, and more. FinFET stands for a fin-shaped field-effect transistor.

What are the different classification of FinFETs?

FinFET Classification. There are two main types of FinFETs: shorted-gate (SG) and independent-gate (IG). SG FinFETs are also known as three-terminal (3T) FinFETs and IG FinFETs as four-terminal (4T) FinFETs.

Are FinFETs CMOS?

Adaptable to existing processing steps: FinFET is not the same as CMOS, as it is a non-planar architecture, but the same process steps can be used for fabrication.

What is difference between FinFET and MOSFET?

FinFETs are three-dimensional structures with vertical fins forming a drain and source. MOSFETs are planar devices with metal, oxide, and semiconductors involved in their basic structure. FinFETs have an excellent subthreshold slope and a higher voltage gain than planar MOSFETs.

What are the disadvantages of FinFET?

Disadvantages of FinFET over CMOS: FinFETs are complex devices to model. Accurate FinFET parasitic extraction is more complicated than a planner. FinFETs are 3D structures that need a high aspect ratio.

What is FinFET process?

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.

Is FinFET a MOSFET?

Key Takeaways. FinFETs are three-dimensional structures with vertical fins forming a drain and source. MOSFETs are planar devices with metal, oxide, and semiconductors involved in their basic structure. FinFETs have an excellent subthreshold slope and a higher voltage gain than planar MOSFETs.

How does current flow in a FinFET?

FinFETs follow width quantization, where the width is designed as the multiples of height. The height of a FinFET is one factor that controls the current flow through the channel between source and drain. The higher the height of a FinFET, the more current flows through the channel.

What is Corner effect?

The corner effect is known as a leakage current enhancement at the edges of the active areas in the shallow trench isolated CMOS transistors. It usually deteriorates the transistor performance.
