A section of semiconductor wafer with circuitry and components etched into the top. Also called a die or chip.
a microelectronic computer circuit incorporated into a chip or semiconductor; a whole system rather than a single component
A "monolithic integrated circuit" or "multichip integrated circuit" containing an arithmetic logic unit (ALU) capable of executing a series of general purpose instructions from an external storage. N.B.1: The "microprocessor microcircuit" normally does not contain integral user-accessible storage, although storage present on-the-chip may be used in performing its logic function. N.B.2: This definition includes chip sets which are designed to operate together to provide the function of a "microprocessor microcircuit".
A circuit consisting of a number of transistors built and interconnected on a single semiconductor substrate. The smallest present-day microcircuit transistors have an approximate gate- length of 0.5 micron.
A small circuit having high equivalent-circuit-element density, which is considered as a single part composed of interconnected elements on or within a single substrate to perform an electronic-circuit function.
