Mostly silicon but other compounds such as gallium arsenide are also used.
Silicon chip, micro-chip, integrated circuit
"Integrated circuit" (IC, or "chip")
Integrated Circuit
The integrated circuit chip.
Integrated circuit
Because if the integrated circuit "The Chip" wasn't invented, Then we would still be using vacuum tubes. Which are weaker, and more expensive to have.
A silicon chip is also called an integrated circuit (IC) or a microchip. It is a small semiconductor wafer on which integrated circuits are fabricated.
It could be an integrated circuit chip made by a company called GSI Technology that is based in Silicon Valley, California.But if you are asking about a GeSi integrated circuit, that could be referring to one that has been fabricated using the elements Germanium and Silicon which have been specially doped to make its semiconductor components.
An integrated circuit or chip consists of a single-crystal chip of silicon, containing both active and passive elements and their interconnections. Or simply defined as a collection of more than 1000 transistors and their interconnections in a single chip!.
The first integrated circuit chip was invented by Jack Kilby working at Texas Instruments in 1958. However it was made of germanium and although it integrated all the components into one chip, the interconnections between them had to be made individually by hand under a microscope. The first prototype integrated circuit he produced was a one transistor analog RC oscillator.The first practical integrated circuit chip was invented by Robert Noyce working at Fairchild Semiconductor in 1959. It was made of silicon and using Fairchild's new planar process developed for making individual transistors, integrated not only all components but also the interconnections; as well as passivating the chip making hermetic sealed packages unnecessary, permitting the use of cheaper plastic packages. The first prototype integrated circuit he produced (in early 1960) was a four transistor Direct Coupled Transistor Logic (DCTL) flip-flop.The first commercially available microprocessor integrated circuit was invented by Federico Faggin, Marcian "Ted" Hoff, and Masatoshi Shima working at Intel in 1971.
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is an electronic circuit on one small plate ("chip") of semiconductor material, normally silicon. Such a circuit can be made very compact, having up to several billion transistors and other electronic components. The width of each conductor (the line width) can be made smaller and smaller as the technology advances, and can now (in 2012) be expressed as a two-digit number of nanometers.
Its another meaning for Microprocessor. Which is any integrated circuit semiconductor that processes digital data.
