What is VLSIAs cmos process technology

improves transistors continue to

get smaller and ICs hold more and

more transistors.

" Larger the integration smaller is

the size“

VLSI Offers

JBTech INDIA

The era of VLSI now offers 64- bit

microprocessors complete with

"cache memory" and "floating

point arithmetic units" Containing

well over a million Transistors on a

single piece of silicon

JBTech INDIA


1. Wafer PreparationBefore the long process of creating an integrated circuit can begin, a wafer of semiconductor material must first be manufactured. Thisessential substrate is the ultimate foundation upon which all integrated circuits are created.

Basic Steps of Silicon Wafer Manufacturing and Preparation steps outlined below.

Thickness Sorting and Flatness CheckingLapping & Etching Processes

Crystal Growth and Wafer Slicing ProcessObtaining the sandPreparing the molten silicon bath Making the ingot Preparing the wafers

Design Entry Simulation Synthesis


Semiconductor device fabrication is the process used to create chips. It is a multiple-step sequence of photographic and chemical processing steps during which electronic circuits are gradually created on a wafer made of pure semiconductingmaterial. Silicon is the most commonly used semiconductor material today, along with various compound semiconductors.

3. What is Fabrication

Mask 1 defines the areas in which the deep p-well diffusions are to take place on an n-type substrate .Mask 2 defines the thinox (or diffusion) regions, namely, those areas where the thick oxide is to be stripped and thin oxide grown to accommodate p and n-transistors and wiresMask 3 is used to pattern the polysilicon layer that is deposited after the thin oxide

Mask 4 is a p-plus mask used to define all areas where p diffusion is to take place.

JBTech INDIA


(cont…)Mask 5 is usually performed using the negative form of the p-plus mask and defines those areas where n-type diffusion is to take place.Mask 6 defines contact cuts .Mask 7 defines the metal layer patternMask 8 is an overall passivation layer that is required to define the openings for access to bonding pads .

India was projected as a software super power, But it has now set its sights on becoming an all-round IT super source as India’s VLSI design engineers join hands with their software developer brethren.

JBTech INDIA


Presently there are more than 400 design Center in India, Forecasting need of large no VLSI Designer in future

JBTech INDIA

The growing dependence on Indian VLSI Design professionals promises a significant opportunity in this area
