Abstract
In an excitation atomic beam source for use in doping impurities to a semiconductor, a magnetic field is generated in a space between a nozzle (12) and a skimmer (13). A microwave discharge is generated in the space to form a plasma in the space by applying microwaves to a gas to be ionized emitted from the nozzle (12). In this manner, high-velocity particles and excited atoms in the plasma are passed through the skimmer (13) to thereby generate a supersonic excitation atomic beam.
