Computers have been around for a long time and their invention as many believe is not as recent. Since the early 19th century people have been toying with the idea of a device that can solve complex numeric problems; fast forward 175 years and today computers can calculate trajectories of multi-planetary space missions with ease. Today these devices can fit in the palm of our hands but are used for multimedia and entertainment purposes.
This drastic change is not something that gradually happened over time, in the last thirty years these devices went from being as big as entire rooms to something that can be a few millimetres wide. Such instrumental change can be credited to constructing advanced circuitry from a single piece of semiconductor.
The problem before this was that the long interconnecting wires and large components made computers extremely slow and inefficient. Making the whole thing out of a single monolith was far better and one could fit in hundreds of components. This also led to the automation of the entire manufacturing process, thus cutting down on costs heavily. The idea was to integrate the circuit on a single silicon wafer, which was termed as SSI (Small Scale Integration). As technology advanced, it turned into medium scale integration and then large scale; and now finally Very Large Scale integration, where one can now fit over billions of components in a single chip.
VLSI has also shrunk in size, components are very tiny and recently we’re on the breakthrough for nanoscale circuitry, which will allow more components to be fitted on a single chip. VLSI can be technically described as circuitry having a million gates and hundreds of millions of transistors, but as of now, it is well beyond this point.
As time progresses and we move into an age of technology, VLSI is very crucial to the development of this era. In a country like India, with its huge young population VLSI may yet play a very critical part for the country to become a global leader. In terms of development India is the second fastest growing country in the world, and rightly so. 1.3 billion People, out of which 650 million are under the age of 25.
The youth of India is bigger than the populations of USA, UK, Japan and Germany combined. This represents a workforce that is set to dominate the world. The literacy rate among the population is also closing in on 80%, which means that the amount of skilled personnel is only set to increase.
With a number of companies investing in India, the requirements for trained individuals in areas like VLSI are very high. In big metros, one can easily find VLSI courses in Bangalore and Delhi at the click of a button, as there are a high number of VLSI institutes in Bangalore and Delhi. As we head into the third decade of the 21st century, India is most likely to become a superpower and the youth have a major role to play. The evolution from agricultural to an industrial nation is upon us and skilled individuals can be required the change.
