How is an integrated circuit manufactured?

Answer 1

In an integrated circuit, electronic components such as resistors, capacitors, diodes, and transistors are formed directly onto the surface of a silicon crystal. The process of manufacturing an integrated circuit will make more sense if one first understands some of the basics of how these components are formed.

Even before the first IC was developed, it was known that common electronic components could be made from silicon. The question was how to make them, and the connecting circuits, from the same piece of silicon? The solution was to alter, the chemical composition of tiny areas on the silicon crystal surface by adding other chemicals, called dopants. Some dopants bond with the silicon to produce regions where the dopant atoms have one electron they can give up. These are called N regions. Other dopants bond with the silicon to produce regions where the dopant atoms have room to take one electron. These are called P regions. When a P region touches an N region, the boundary between them is referred to . This boundary is only 0.000004 inches (0.0001 cm) wide, but is crucial to the operation of integrated circuit components.

Answer 2

An integrated circuit - or IC - chip is a circuit made with components such as transistors, diodes and resistors that are usually formed simultaneously on a small chip of silicon.

......

Two or more transistors (and they're up to many millions now) AND some (or all) of their interconnections on a single (tiny) slab of silicon.

......

The components are connected with aluminum wires deposited both on the surface and within the body of the chip. ICs can contain as few as several to as many as hundreds of thousands of transistors.

Integrated circuits are electronic parts that have a complete electronic circuit inside formed by transistors, resistors and capacitors, that has the purpose of simplifying some branchs of the circuit in a electronic device.

Answer 3

to understand how integrated circuits work, you must you must know very well about the term "integrated" and the term"circuit". and what the two simply means is circuits joined together. and this compatibility is made possible by semiconductors and with an enhanced technical skill.

Answer 4

That will depend on the type of the integrated circuit. There are far too many completely different types of integrated circuits to make any meaningful comment here. A typical manufacturer's data book for just one family of related integrated circuit types can be over 3 inches thick! Many of the integrated circuits in such a family are fully explained in just a couple pages of that data book.

I have a set of data books (in PDF files) on using just one type of microprocessor integrated circuit, each data book in this set is over 2500 pages in length. Until you read in full all these data books in this set you will not know how to use that integrated circuit anywhere!

Answer 5

just type the name of ic and browse for data sheet
