PRESENTATION ON TRI GATE TRANSISTOR PREPARED BY: SANDEEP (1706435)

INTRODUCTION Transistors are the microscopic, silicon-based switches that process the ones and zeros of the digital worlds and are the fundamental building block of all semiconductor chips. With traditional planar transistors, electronic signals travel as if on a flat, one-way road.

DEFINITION

HISTORY Since their inception in the late 1950s, planar transistors have acted as the basic building block of microprocessors. The scaling of planar transistors requires the scaling of gate oxides and source/drain junctions. In 2002 Intel developed the world’s first CMOS tri-gate transistor,which employs a novel three-dimensional gate design that improves the drive current. Tri- gate transistors are expected to replace the nanometer transistors in the Intel microprocessors by 2010

ARCH The tri-gate is built on an ultra-thin layer of fully depleted silicon for reduced current leakage. This allows the transistor to turn on and off faster, while dramatically reducing power consumption. It also incorporates a raised source and drain structure for low resistance, which allows the transistor to be driven with less power. The design is also compatible with the future introduction of a high K gate dielectric for even lower leakage.

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.

ADVANTAGE 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 .
