Big ol' chip.

The microchip revolution had its beginnings with the inventions of integrated circuit (IC) and the microprocessor, both of which were developed to increase computer efficiency. This in turn caused the much broader digital revolution, one of the most significant occurrences in the history of humankind.

An integrated circuit or monolithic integrated circuit (also referred to as IC, chip, or microchip) is an electronic circuit manufactured by the patterned diffusion of trace elements into the surface of a thin substrate of semiconductor material. Additional materials are deposited and patterned to form interconnections between semiconductor devices.

Integrated circuits are used in virtually all electronic equipment today and have revolutionized the world of electronics. Computers, mobile phones, and other digital appliances are now inextricable parts of the structure of modern societies, made possible by the low cost of production of integrated circuits.
