Culture definitions for microchip


The basic component of modern miniaturized electronics. The “chip” is a series of electrical circuits built into a tiny wafer of silicon or another semiconductor.


These circuits may be made by exposing the chip to a high-temperature vapor of controlled composition. The vapor deposits a thin layer (sometimes only a few atoms thick) on the silicon. In this way complex layers of materials, such as those found in transistors can be built up in a very small area.
