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 integrated circuit (IC).
These ideas could not be implemented by the industry in the early 1950s, but 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. Kurt Lehovec of Sprague Electric Company invented a way to electrically isolate components on a semiconductor crystal. Robert Noyce of Fairchild Semiconductor invented a way to connect the IC components (aluminium metallization) and proposed an improved version of insulation based on the planar technology by Jean Hoerni. On September 27, 1960, using the ideas of Noyce and Hoerni, a group of Jay Last's at Fairchild Semiconductor created the first operational semiconductor IC. Texas Instruments, which held the patent for Kilby's invention, started a patent war, which was settled in 1966 by the agreement on cross-licensing.
There is no consensus on who invented the IC. The American press of the 1960s named four people: Kilby, Lehovec, Noyce and Hoerni; in the 1970s the list was shortened to Kilby and Noyce, and then to Kilby, who was awarded the 2000 Nobel Prize in Physics "for his part in the invention of the integrated circuit". In the 2000s, historians Leslie Berlin, Bo Lojek and Arjun Saxena reinstated the idea of multiple IC inventors and revised the contribution of Kilby.
During and right after World War II a phenomenon named "the tyranny of numbers" has been noticed, that is, some computational devices reached a complexity at which the losses from failures and downtime exceeded the expected benefits. Each Boeing B-29 (put into service in 1944) carried 300–1000 vacuum tubes and tens of thousands of passive components. The number of vacuum tubes reached thousands in advanced computers and more than 17,000 in the ENIAC (1946).Each additional component reduced the reliability of a device and lengthened the troubleshooting time. Traditional electronics reached a deadlock that a further development of electronic devices required reducing the number of their components.
The invention of the transistor in 1948 led to the expectations of a new technological revolution. Fiction writers and journalists heralded the imminent appearance of "intelligent machines" and robotization of all aspects of life. Although transistors did reduce the size and power consumption, they could not solve the problem of reliability of complex electronic devices. On the contrary, dense packing of components in small devices hindered their repair. While the reliability of discrete components was brought to the theoretical limit in the 1950s, there was no improvement in the connections between the components.
Early developments of the integrated circuit go back to 1949, when the German engineer Werner Jacobi (de) (Siemens AG) filed a patent for an integrated-circuit-like semiconductor amplifying device showing five transistors on a common substrate in a 3-stage amplifier arrangement with two transistors working „upside-down“ as impedance converter. Jacobi disclosed small and cheap hearing aids as typical industrial applications of his patent. An immediate commercial use of his patent has not been reported.
On May 7, 1952, the British radio engineer Geoffrey Dummer formulated the idea of integration in a public speech in Washington:
With the advent of the transistor and the work in semiconductors generally, it seems now to be possible to envisage electronic equipment in a solid block with no connecting wires. The block may consist of layers of insulating, conducting, rectifying and amplifying materials, the electrical functions being connected by cutting out areas of the various layers.
ummer later became famous as "the prophet of integrated circuits", but not as their inventor. In 1956 he produced an IC prototype by growth from the melt, but his work was deemed impractical by the UK Ministry of Defence, because of the high cost and inferior parameters of the IC compared to discrete devices.
In the United States, in October 1952, Bernard Oliver filed a patent application for a method of manufacturing three electrically connected planar transistors on one semiconductor crystal.
