Integrated Circuit

Integrated circuit showing memory blocks, logic and input/output pads around the periphery microchips with a clear window, showing the integrated circuit inside. Note the fine silver-colored wires that connect the included circuit to the pins of the package. A monolithic integrated circuit is a miniaturized electronic circuit that has been manufactured in the surface of a thin substrate of semiconductor material. A hybrid integrated circuit is a miniaturized electronic circuit constructed of human being semiconductor devices, as well as passive components, bonded to a substrate or circuit board. This article is about monumental integrated circuits.
