Patent ID: 8450819

Claim:
A plasma doping apparatus comprising: a casing that forms a cylindrical chamber having a slit-shaped opening portion, with a longitudinal direction of the opening portion and a longitudinal direction of the cylindrical chamber being set in parallel with each other; a gas supply device that supplies a gas into the chamber; a coil for use in generating a high-frequency electromagnetic field in the chamber; a high-frequency power supply for supplying a high-frequency power to the coil; a base material placing table disposed to face the opening portion, on which a base material is placed; a moving device that relatively moves the chamber and the base material placing table relative to each other in a direction perpendicular to a longitudinal direction of the opening portion; and an elongated member provided at least at one portion of an inner wall surface of the cylindrical chamber, or between the cylindrical chamber and the base material placing table, the member extending in the longitudinal direction of the cylindrical chamber, and being made of a material containing atoms or molecules to be doped, wherein the atoms or molecules are doped in a semiconductor configuring a surface of the base material.
