The Integrated Circuit &IC'

• An IC consists of interconnected electronic componentsin a single piece (“chip”) of semiconductor material

!he first planar IC

(actual si"e# $$% in diameter)

• In &'' *obert +oyce(Fairchild Semiconductor )demonstrated an IC made insilicon using ,i-. as the

insulator and Al for themetallic interconnects

• In &' 0ac1 , 2ilby(Texas Instruments)sho3ed that it 3aspossible to fabricate asimple IC in germanium

• 4y connecting a large number of components eachperforming simple operations an IC that performsvery comple5 tas1s can be built

• !he degree of integration has increased at ane5ponential pace over the past 67$ years

, !he number of devices on a chip doublesevery 6& months for the same price.
