INTRODUCTION
Microscopic, silicon-based switches .
Fundamental building block of modern electronic devices.
With traditional planar transistors, electronic signals travel as if on a flat, one-way road.
The approach has served the semiconductor industry well since 1960’s.
HISTORY
1950s- planar transistors acted as the basic building block of microprocessors.
2002 -Intel developed the world’s first CMOS tri-gate(3-D) transistors.
Performance improved by integrating the tri-gate design with silicon process technology.
Tri- gate transistors(22nm) are expected to replace the 32 nanometer transistors in the Intel microprocessors by 2012.
TRIGATE TRANSISTORS
3-D structure
Runs faster, better performance
Reduces conventional transistor size
Reduces power dissipation
Increases battery life of mobile devices
ADVANTAGES
Dramatic performance gain at low operating voltage.
37% performance increase at low voltage.
50% power reduction at constant performance.
Improved switching characteristics.
Higher drive current for a given transistor footprint.
Only 2-3 % cost adder.
APPLICATIONS
Critical part of INTEL's energy efficient performance.
Scaling of silicon transistors.
Increase battery life of mobile devices.
Boon for heavy duty network servers.
CONCLUSION
Compared to today’s 32nm transistors, this tri-gate transistor can offer
- 37% performance increase at low voltage.
- 50x reduction in off current.
- improved switching characteristics.
It is believed that these transistors could become the basic building blocks for future microprocessors.
These results give us high confidence that we can continue Moore's law scaling well into next decade.
