Abstract:
1. A plasma doping method, comprising the steps of: supplying a gas into a vacuum container while discharging an interior gas of the vacuum container, the vacuum container having a portion made of a dielectric material and fixedly bearing boron and/or phosphorus; and controlling a pressure of an interior of the vacuum container at a certain pressure while supplying a high frequency electric power with a first frequency to a coil or an antenna disposed adjacent the dielectric material portion of the vacuum container, generating a plasma within the vacuum container, impinging ion in the plasma on the dielectric material portion to emit the boron and/or phosphorus therefrom, and implanting the emitted boron and/or phosphorus into a substrate placed on an electrode disposed within the vacuum container.
