Integrated circuit – The raison d'être for Moore's law.
Size weight and reliability were some of the prime requirements. If a chip failed these tests, the entire lot from which it came from was discarded. For the silicon based integrated circuit, Robert Noyce and the Fairchild Semiconductor Corporation received the US patent #2,981,877.
So, scientists wanted to make a whole circuit -- the transistors, the wires, everything else they needed -- in a single blow. The two companies wisely decided to cross-license their technologies after several years of legal battles, creating a global market now worth about $1 trillion a year.In 1961 the first commercially available integrated circuits came from the Fairchild Semiconductor Corporation. Sure, transistors were smaller than vacuum tubes, but for some of the newest electronics, they weren't small enough.One day in late July, Jack Kilby was sitting alone at Texas Instruments. An early attempt at combining several components in one device (like modern ICs) was the Loewe 3NF vacuum tube from the 1920s. As with many inventions, two people had the idea for an integrated circuit at almost the same time. All computers then started to be made using chips instead of the individual transistors and their accompanying parts. 1958: Invention of the Integrated Circuit.
The idea caught the imagination of many engineers and scientists but the reality of their high cost limited their use to a very small number of specialised applications.the invention of the IC required many elements to be in place: the transistor, silicon processing technology, ideas about printed circuits, and many more.It was as a result of a quirk in the company bureaucracy that major advances were made. In view of their complementary work, Kilby and Noyce are jointly credited with the invention of the IC.Then in 1961 President Kennedy announced his vision for space research saying that America would place a man on the moon by the end of the decade. The halls were deserted, and he had lots of time to think. 1. Even military equipment which tended to use tried and tested technologies was starting to become transistorised in some areas.With this change it soon became apparent that transistors could give significant improvements in reliability and size reduction. The germanium hybrid IC was invented by Jack Kilby at Texas Instruments in 1958, followed by the invention of the silicon monolithic IC chip by Robert Noyce at Fairchild Semiconductor in 1959. The next step in the development of integrated circuits introduced devices which contained hundreds of transistors on each chip, called "medium-scale integration" (MSI).Initially, ICs were strictly electronic devices. The first integrated circuit (IC) was created by Jack Kilby of Texas Instruments on September 12, 1958. While Kilby had hammered out the details of making individual components, Noyce thought of a much better way to connect the parts. Please try again."What we didn't realize then was that the integrated circuit would reduce the cost of electronic functions by a factor of a million to one, nothing had ever done that for anything before" - Jack Kilby
The transistors were already at the limit of what steady hands and tiny tweezers could handle. Knowing that TI had already filed a patent on something similar, Fairchild wrote out a highly detailed application, hoping that it wouldn't infringe on TI 's similar device.All that detail paid off. 1958: The Integrated Circuit is Invented by Jack Kilby. He also realized a whole circuit could be made on a single chip. Called a phase shift oscillator, the integrated circuit consisted of only one transistor, one capacitor, and three resistors, as shown in Figure 2.1. Integrated circuits and the patents Jack kilby and Robert invented ICs that varied in their raw materials and construction.
In January of 1959, Robert Noyce (see his biography) was working at a small startup company—Fairchild Semiconductor, which he and 7 of his colleagues established in 1957, leaving Shockley Semiconductor.He also realized a whole circuit could be made on a single chip. Unlike ICs, it was designed with the purpose of tax evasion, as in Germany, radio receivers had a tax that was levied depending on how many tube holders a radio receiver had.
