Basics of Mosfet Scaling


2/26



INTRODUCTION TO MOSFET SCALING

The lateral dimensions and interconnect of the IC are reduced.

This reduction in size is known as Scaling .

Minimum feature size is the smallest size of the IC(gate length or

the interconnect).

Minimum feature size has shrunk over the time of several years.

As a result the number of transistors on the IC has increased a lot
