Find out what a silicon chip is.
A silicon chip is an almost pure piece of silicon, usually less than one centimeter square and about half a millimeter thick. It contains hundreds of thousands of microminiature electronic circuit components, mainly transistors, packed and interconnected in layers beneath the surface. These components can perform control, logic, and/or memory functions. There is a grid of thin metallic strips on the surface of the chip; these wires are used for electrical connections to other devices. The silicon chip was developed independently by two researchers: Jack Kilby of Texas Instruments in 1958, and Robert Noyce (b. 1927) of Fairchild Semiconductor in 1959.
While silicon chips are essential to most computer operation today, a myriad of other devices depend on them as well, including calculators, microwave ovens, automobile diagnostic equipment, and VCRs.
