Overview
An Inductively Coupled Plasma (ICP) is a type of plasma source in which the energy is
supplied by electrical currents produced by electromagnetic induction; that is, by time-
varying magnetic fields. In its simplest form, an inductively coupled plasma consists of a
vacuum vessel, into which the gas to be ionized is administered, and an induction coil,
driven by a source of RF power. The coil is generally separated from the vacuum region
by a dielectric window. The wide range of applications for RF-driven, inductively
coupled plasma sources has recently expanded into processing tools for coating or
etching systems in the microelectronics industry.
