What is Integrated Circuit: Forms, Purposes, & Applications of Integrated Circuit?

We now have observed over the years that technology has changed continuously and was able to squeeze itself in a smaller and concise structure. Let’s take an example of the principal computers which were made were the size of a warehouse of 1000 laptops which we use today. Think about how this has been made possible? The solution to it’s integrated circuits.

The circuits which were made previously were substantial and ponderous, having a circuit components like resistor, transistor, diodes, capacitor, inductor, etc. which are connected alongside copper wires. This factor limited the effective use of the circuits to big machines. It was impossible to create small, and compact appliances with these big circuits. Moreover, they weren’t entirely shockproofed and reliable.

As stated, necessity may be the mother of inventions, similarly, the modern technologies all are the effect of it. There was a requirement to produce circuits of smaller size with more power and safety to include them into devices. Then were three American scientists who invented transistors which simplified what to quite a degree, nevertheless it was the development of integrated circuits that changed the eye of electronics technology.

What’s Integrated Circuit?
An integrated circuit (IC), it often could be referred to as a chip or even a microchip is a compilation of transistors which are added to silicon. An integrated circuit is simply too small in proportions, when it’s in comparison to the standard circuits that are made of the independent circuit components, it is about how big a fingernail. IC is a semiconductor wafer (also called a skinny slice of semiconductor, like crystalline silicon) which thousands or countless tiny resistors, capacitors, and transistors are fabricated.

Modern electronic circuits aren’t comprised of individual, means they cannot be composed of separated components as used to be true. Instead, many small circuits are embedded in a single complex bit of silicon as well as other materials called a circuit(IC), or chip or microchip. The output of integrated circuits starts off with a simple circular wafer of silicon several inches across.

Firstly designers made drawings of in which each consider each the main circuit is usually to go in order that the processing would become easy. A picture of each diagram will be reduced in size repeatedly to provide a little photolithographic mask.

The silicon wafer is coated which has a material known as a photoresist that undergoes a chemical process when encountered with ultraviolet light. Ultraviolet light shown through the mask on top of the photoresist creates an equivalent pattern on the wafer as much like that mask. Then solvents etch into the elements of the resist which are subjected to the sunlight, leaving one other parts intact. Then another layer of an silicon material doped with a few impurities so that it is laid down in the wafer, and the other pattern is etched in by way of a similar technique.

The consequence of these operations is a multilayered circuit, with many different countless tiny transistors, resistors, and conductors created within the wafer. The wafer is then broken apart along prestressed lines into many identical square or rectangular chips, that’s the end of integrated circuits.
