Abstract
Disclosed is a plasma doping apparatus provided with a plasma generating mechanism. The plasma generating mechanism includes a microwave generator that generates microwave for plasma excitation, a dielectric window that transmits the microwave generated by the microwave generator into a processing container, and a radial line slot antenna formed with a plurality of slots. The radial line slot antenna radiates the microwave to the dielectric window. A control unit controls the plasma doping apparatus such that a doping gas and a gas for plasma excitation are supplied into the processing container by a gas supply unit in a state where the substrate is placed on a holding unit, and then plasma is generated by the plasma generating mechanism to perform doping on the substrate such that the concentration of the dopant implanted into the substrate is less than 1×10atoms/cm.
