FUTURE TRENDS IN
SEMICONDUCTOR TECHNOLOGIES

INTRODUCTION


What

is

Semiconductor

?


A

semiconductor

is

a

material

that

behaves

in

between

a

conductor

and

an

insulator
.



At

ambient

temperature,

it

conducts

electricity

more

easily

than

an

insulator,

but

less

readily

than

a

conductor
.




At

very

low

temperatures,

pure

or

intrinsic

semiconductors

behave

like

insulators
.


The

addition

of

impurities

to

a

pure

semiconductor

can

also

increase


its

conductivity
.

Current Semiconductors:


Traditional Si,
Ge
,
GaAs

etc…


Impurities: Phosphorous, Boron etc...



Application:


All electronics devices


Microprocessors


Various gadgets etc…

Current Semiconductors:


SOI(

silicon

on

Insulator)


Improved

version

of

fabrication

process

for

Si



Addition

of

SiO
2


or

sapphire



Improves

Performance


Radiative

sensitive

application



Reduces

parasatic

capacitance


Drastic

increase

in

substrate

cost

Future Trends

Carbon Semiconductors:


Why carbon semiconductors ?



Electricity
can conduct through
carbon


Carbon is not used as semiconductor


Size of carbon is very small


Speedy operation


Strong and rugged in construction
