Transistor and is ubiquitous in modern electronic systems. Julius Edgar Lilienfeld patented a field-effect transistor in 1926 but it was not possible to actually construct a working device at that time. The first practically implemented device was a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement.
Invention of the integrated circuit ahead in the revenue: 32% of the IC market in 1964 compared to 18% of Fairchild. The above logic ICs were built from standard components, with sizes and configurations defined by the technological process, and all the diodes and transistors on one IC were of the same type. The use of different transistor types was first proposed by Tom Long at Sylvania in 1961–1962. In late 1962, Sylvania launched the first family of transistor-transistor logic (TTL) ICs, which became a commercial success. Bob Widlar from Fairchild made a similar breakthrough in 1964–1965 in analog ICs (operational amplifiers). In 1959–1961 years,
