Transistors
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

5. 3-D structure
Runs faster,better perfomance
Reduces conventional transistor size
Reduces power dissipation
Increases battery life of mobile devices

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

7. 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

Moore's law describes a long-term trend in the history of
computing hardware, in which the number of transistors
that can be placed inexpensively on an integrated circuit has
doubled approximately every two years.Moore's law
21st centuries precisely describes a driving force of
technological and social change in the late 20th and early.
