Abstract:
A substrate processing device comprising:a reactor equipped with a substrate holder and a gas feed electrode facing the substrate holder,a pump mechanism for pumping out an interior of the reactor,a reaction gas feed mechanism for introducing a reaction gas through the gas feed electrode into the interior of said reactor,a high frequency power source for applying a high frequency power to said gas feed electrode,a sidewall of the reactor, the sidewall having a first end adjacent the reaction gas feed mechanism and a second end opposite the first end,a connecting port formed in the sidewall of said reactor, the connecting port being located at the second end of the sidewall where the connecting port is as far as possible from the gas feed electrode,said pump mechanism is connected to the connecting port formed in the sidewall of the reactor, and a space between the gas feed electrode and the substrate holder is set so that a conductance between the gas feed electrode and the substrate holder is lower than a conductance between the sidewall of the reactor and the gas feed electrode, and the conductance between the gas feed electrode and the substrate holder is lower than a conductance between the sidewall of the reactor and the substrate holder.
