Brief overview of Semiconductor Industry & its flow

Introduction

ASIC Vs General Purpose IC

If { G is on}{ Current flows through D & S}

What Makes all this happen ?

How Do We Build Them?

OLD VERSION

BIOS ROM CHIP• A program burned onto it • Knows where to look for, and how to access, the different expansion slots,

ports, drives, and the Operating System.

Moore’s Law On April 19, 1965 Moore predicted the most important law ever proposed in Semiconductors.

”number of transistors in a dense integrated circuit doubles approximately every two years.”

INTEL Processor’s Growth

* All the predictions are based on wiki…could be approximate

Should We call It a processor or System on chip

{SOC}?

WHAT LIES AHEAD ????

Bio Inspired ComputationsBrains demonstrate– massive parallelism (1011 neurons)– massive connectivity (1015 synapses)– excellent power efficiency

• much better than today’s microchips– low-performance components (~ 100 Hz)– low-speed communication (~ metres/sec)– adaptivity – tolerant of component failure– autonomous learning

Flexible Electronics
