    • PURPOSE: A plasma doping method and a plasma doping apparatus are provided to stably perform a low-concentration doping operation by including a high frequency power unit which supplies high frequency power through a matching circuit. CONSTITUTION: A vacuum container(1) includes a plasma generator(8). High frequency power is supplied to the plasma generator and generates plasma inside the vacuum container. The high frequency power is supplied to the sample electrode(6) in the vacuum container, and a low-concentration plasma doping process is performed with respect to a substrate on the sample electrode. The progressive wave and the reflected wave of the high frequency power is sample. If an integration value of the progressive wave and the reflected waves reaches to a pre-set value, the high frequency power is stop being supplied.

    • PURPOSE: To provide a method and an apparatus for plasma doping having the superior controllability of an impurity concentration introduced on the surface of a sample, and to provide a matching circuit suitable for the method and the apparatus. CONSTITUTION: When an evacuated vessel 1 is exhausted by a pump 3, while predetermined gas is introduced from a gas supply unit 2 into the vessel 1, high-frequency power is applied to a coil 8 by a high-frequency power source 5, and while the container 1 is maintained at predetermined pressure, plasma is generated in the vessel 1, and a substrate 9 placed on a sample electrode 6 can be plasma-doped. Then, an impurity concentration can be controlled based on a measured value by an emission spectroscopic apparatus 13 and a measured value by a high-frequency voltage-measuring unit 15.
