London, Sept 12 : The microchip, used in devices from cookers to computers to mobile phones, is 50 years old today.
Consisting of a strip of germanium with one transistor and other components all glued to a glass slide, the first working microchip, or integrated circuit, was demonstrated at Texas Instruments by one of the company’s newest employees, Jack Kilby, on September 12, 1958.
His rough device, measuring seven 16ths of an inch (11.5 millimetres) by one 16th of an inch, revolutionised electronics, and the world.
The microchip virtually created the modern computer industry, and the Internet would be unthinkable without it.
