What are Computer Chips Made Of

Computer chips are small electronic circuits manufactured from semiconductor materials like silicon. A computer chip consists of an electronic circuit, which is embedded onto a semiconducting material. Typically, a computer chip is very small in size and bears several electronic components on it. In a computer, there are many such chips that are placed on electronic boards known as printed circuit boards (PCB).


When it was discovered that semiconductor devices could perform the functions of vacuum tubes, integrated circuits were born. It was Geoffrey W.A. Dummer, a radar scientist, who came up with the idea of building integrated circuits for the very first time. In 1956, he made an unsuccessful attempt of building a chip. Jack Kilby of Texas Instruments and Robert Noyce of Fairchild Semiconductor co-invented the integrated circuit around the same time. Since the development of integrated circuits, they have been used in computers and cell phones.

The microprocessor is the most complex chip in a computer. A microprocessor is capable of executing millions of instructions every second. Be it a desktop or a laptop, the microprocessor is the most vital component of a computer system. Interestingly, a microprocessor is nothing but a computer chip in itself!
