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 1×1013 atoms/cm2.

Abstract:
Disclosed is a plasma doping apparatus including a processing chamber, a substrate holding unit, a plasma generating mechanism, a pressure control mechanism, a bias power supply mechanism, and a control unit. The control unit controls the pressure within the processing chamber to be a first pressure and controls the bias power to be supplied to the holding unit is to be a first bias power for a first plasma process. The control unit also controls the pressure within the processing chamber to be a second pressure which is higher than the first pressure, and controls the bias power to be supplied to the holding unit to be a second bias power which is lower than the first bias power for a second plasma process.
