integrated circuit (IC)or microcircuit or chip or microchipAssembly of microscopic electronic components (transistors, diodes, capacitors, and resistors) and their interconnections fabricated as a single unit on a wafer of semiconducting material, especially silicon. Early ICs of the late 1950s consisted of about 10 components on a chip 0.12 in. (3 mm) square. Very large-scale integration (VLSI) vastly increased circuit density, giving rise to the microprocessor. The first commercially successful IC chip (Intel, 1974) had 4,800 transistors; Intel's Pentium (1993) had 3.2 million, and more than a billion are now achievable. microcircuitA miniaturized, electronic circuit, such as is found on an integrated circuit. See chip and MCM. microcircuit a miniature electronic circuit, esp one in which a number of permanently connected components are contained in one small chip of semiconducting material How to thank TFD for its existence?

| I am your great-grandfather come again to leave a fresh impression on a microcircuit of the cosmos. By linking loops of silicon on a microcircuit, researchers have taken a major stride toward using light to shuttle information within computer chips. Products include inverter electronics from 5 kilowatts to 5 megawatts, power switches, and hybrid microcircuits for industrial, medical, military and aerospace applications. |
