• 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
TRI GATE TRANSISTORS

• 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 worlds 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

• 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.

• Lower leakage and consume much less power.
• Faster cooler operation.
• 45 increase in speed or 50x reduction in
  off-current.
• The basic building blocks for future
  microprocessors.
• Moore's Law scaling can be taken well into the
  next decade .
