Introduction
[1] Jack Kilby holding integrated circuits
The first integrated circuit, a circuit of transistors, resistors, and capacitors constructed on a single semiconductor wafer or chip, in which the components are interconnected to perform a given function, [2] was created and successfully demonstrated by Jack Kilby in 1958. [1]
Overview
Before the integrated circuit, transistors were used in common electronics such as cell phones, radios and computers but the transistors would eventually become to large for these such electronics. People wanted to find a way to have a transistor and its needed components in one item. In 1958, the first integrated circuit was made. [3] The first integrated circuit was composed of a transistor and other components on a slice of germanium. [1] The integrated circuit made it possible to store more information in a smaller area. Also, the transistor on the integrated circuit had made the machines that it was in run faster, it cost less and was more reliable. [4] It was created by Jack Kilby while he was working for Texas Instruments in 1958. He received a U.S. patent #3,138,743 for his creation of the first integrated circuit also known as miniaturized electronic circuits. Jack Kilby was an engineer with a background in ceramic-based silk screen circuit boards and transistor-based hearing aids. [5]
Significance
