microcircuit
(redirected from microcircuits)

   Also found in: Dictionary/thesaurus 0.01 sec.

integrated circuit (IC)

 or microcircuit or chip or microchip

Assembly 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.


microcircuit

A 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

As the number of modules per chip continues to multiply in the coming decade, the data traffic is expected to outstrip the information-handling capacity of the electronic microcircuits that carry and route the traffic, says Yurii A.
Products include inverter electronics from 5 kilowatts to 5 megawatts, power switches, and hybrid microcircuits for industrial, medical, military and aerospace applications.
This is an important step in the race to make ever smaller microcircuits, because the oxide layer thickness must be reduced proportionately.
