    Abstract: An objective of the present invention is to provide a plasma doping apparatus for stably doping a substrate to be treated, and to increase surface uniformity of dopant on the substrate to be treated. A plasma generation device (39) provided in the plasma doping apparatus (31) includes a microwave generation unit (35) to generate a microwave for plasma excitation; a dielectric window (36) allowing the microwave generated from the microwave generation unit (35) to be transmitted into a processing vessel (32); and a radial line slot antenna (37) provided thereon with a plurality of slots to radiate the microwave to the dielectric window (36). A control unit (28) controls a gas supplying unit (33) to supply a doping gas and a gas for the plasma excitation into the processing vessel (32) while positioning a substrate (W) to be treated on a supporting unit (34), and controls the plasma generation device (39) to generate the plasma after the doping gas and the gas for the plasma excitation are supplied by the gas supplying unit (33) so that doping is performed on the substrate (W) such that a density of a dopant implanted into the substrate (W) to be treated is less than 1X1013atoms/cm2.
