Microscopic, silicon-based switches

Fundamental building block of all semiconductor chips.

With traditional planar transistors, electronic signals travel as if on a flat, one-way road.

Transistors shrink to less than 30 nanometers

3-D structure

Runs faster,better perfomance

Reduces conventional transistor size

Reduces power dissipation

Increases battery life of mobile devices

TRI GATE TRANSISTORS

H I S T O R Y

1950s- planar transistors acted as the basic building block of microprocessors.

2002 -Intel developed the world’s first CMOS tri-gate transistors.

Performance improved by integrating the tri-gate design with silicon process technology

Tri- gate transistors are expected to replace the nanometer transistors in the Intel microprocessors by 2012

A R C H I T E C T U R E

Built on an ultra-thin layer of fully depleted silicon

Raised source and drain structure

Compatible with the future introduction of a high K gate dielectric

Show excellent DIBL

Thickness requirement of the Si layer is also relaxed by about 2-3 times
