who invented integrated circuit
Answers
Explanation:
The integrated circuit (IC) chip was invented during 1958–1959. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi [de] developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic components in a monolithic semiconductor crystal in 1952. A year later, Harwick Johnson filed a patent for a prototype IC. Between 1953 and 1957, Sidney Darlington and Yasuro Tarui (Electrotechnical Laboratory) proposed similar chip designs where several transistors could share a common active area, but there was no electrical isolation to separate them from each other.
These ideas could not be implemented by the industry, until a breakthrough came in late 1958. Three people from three U.S. companies solved three fundamental problems that hindered the production of integrated circuits. Jack Kilby of Texas Instruments patented the principle of integration, created the first prototype ICs and commercialized them. Kilby's invention was a hybrid integrated circuit (hybrid IC), rather than a monolithic integrated circuit (monolithic IC) chip.[1] Between late 1958 and early 1959, Kurt Lehovec of Sprague Electric Company developed a way to electrically isolate components on a semiconductor crystal, using p–n junction isolation.
