Vlsi design and fabrication

ABSTRACT

The electronics industry has achieved a phenomenal growth over the last two decades, mainly due to the rapid advances in integration technologies, large-scale systems design - in short, due to the advent of  VLSI ( Very Large Scale Integrated Circuits).The microscopic dimension of current silicon–Integrated Circuitry make possible the design of digital circuits which may be very economical in space, power requirements and cost, and potentially very fast .This integration involves packing more and more logic devices in a  small area basically depending on  MOORE’S LAW. The combination of complexity and speed is finding ready application for VLSI systems in digital processing, and particularly in those application areas requiring sophisticated high speed digital  processing.
This paper elucidates about the evolution of integrated circuits, design aspects of  VLSI, its fabrication methods and testing. It also deals with the application of  VLSI , besides touching up the important aspects of impediments and advancements in VLSI technology.
