Integrated Circuits
An integrated circuit (IC) is a thin chip consisting of at least two
interconnected semiconductor devices, mainly
transistors, as well as passive components like resistors. As of 2004, typical
chips are of size 1 cm2 or smaller, and
contain millions of interconnected devices, but larger ones exist as well.
Among the most
advanced integrated circuits are the microprocessors, which drive everything
from computers to cellular phones to digital microwave ovens. Digital memory
chips are another family of integrated circuits that are crucially important in
modern society.
Integrated circuits
were made possible by mid-20th-century technology advancements in semiconductor
device fabrication and experimental discoveries that showed that semiconductor
devices could perform the functions performed by vacuum tubes at the time. The
integration of large numbers of tiny transistors onto a small chip was an
enormous improvement to the manual assembly of finger-sized vacuum tubes. The
integrated circuit's small size, reliability, fast switching speeds, low power
consumption, mass production capability, and ease of adding complexity quickly
pushed vacuum tubes into obsolescence.
