Abstract:
A sputtering device provided with two electrodes I and II of parallel plate type within a vessel inside which pressure can be reduced, wherein:a target to be sputtered is placed on said electrode I, and a base body on which a film is to be deposited is placed on said electrode II, with the target and the base body being opposed to each other;a process gas is introduced into said vessel from a gas supply system;a means for generating a magnetic field with a particular magnetic field oriented horizontal to a sputterable surface of the target;a radio frequency power is applied to said target through at least said electrode I so as to excite plasma between the electrode I and the electrode II;an auxiliary electrode B is supplied; anda frequency fc of a radio frequency power is applied to said auxiliary electrode B, said frequency being higher than a frequency f of the radio frequency power applied to said target through said electrode I.
