We’ve observed over the years that technology has changed continuously and managed to squeeze itself in to a more compact and concise structure. Let’s take an example of the main computers which were made were the size of a warehouse of 1000 laptops which we use today. Consider how it has been turned possible? The answer to it is integrated circuits.
The circuits which were made previously were large and ponderous, having a circuit components like resistor, transistor, diodes, capacitor, inductor, etc. which were connected alongside copper wires. This factor limited the utilization of the circuits to big machines. It turned out impossible to create small and compact appliances using these big circuits. Moreover, they weren’t entirely shockproofed and reliable.
As mentioned, necessity will be the mother of most inventions, similarly, the newest technologies each is the consequence of it. There was clearly absolutely vital to formulate circuits of smaller size with an increase of power and safety to incorporate them into devices. Once there 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 facial skin of electronics technology.
What is Integrated Circuit?
A circuit (IC), sometimes it might be known as a chip or a microchip can be a compilation of transistors which are positioned on silicon. A circuit is way too small in space, when it’s compared to the standard circuits which can be made of the independent circuit components, it is about the size of a fingernail. IC is really a semiconductor wafer (also called a thin slice of semiconductor, like crystalline silicon) where thousands or an incredible number of tiny resistors, capacitors, and transistors are fabricated.
Modern electronic circuits aren’t made up of individual, ensures they can not be made up of separated components as used to be the case. Instead, many small circuits take hold in a complex bit of silicon as well as other materials called a circuit(IC), or chip or microchip. The production of integrated circuits commences with a straightforward circular wafer of silicon several inches across.
Firstly designers made drawings of in which each aspect in each the main circuit is usually to go so that the processing would become easy. An image of each diagram will then be reduced in dimensions repeatedly to produce a little photolithographic mask.
The silicon wafer is coated with a material termed as a photoresist that undergoes a chemical process when subjected to ultraviolet light. Ultraviolet light shown from the mask on the photoresist creates a similar pattern about the wafer as comparable to that mask. Then solvents etch to the aspects of the resist which are exposed to the lighting, leaving one other parts intact. Then another layer of your silicon material doped with many impurities that it is set on top of the wafer, and another pattern is etched in with a similar technique.
The effect of these operations is really a multilayered circuit, with many different millions of tiny transistors, resistors, and conductors created inside wafer. The wafer is then broken apart along prestressed lines into many identical square or rectangular chips, that’s no more integrated circuits.
