Abstract:
A reactive sputtering apparatus comprising:a substrate holder for holding a substrate;a target holder for holding a target;a sputter gas supply for supplying into a reaction chamber a sputter gas for sputtering the target;a reactive gas supply for supplying a reactive gas;a power source for generating a discharge between the target and the substrate;a partition member having a plurality openings having an aspect ratio of less than 0.6 provided between the target and the substrate;a shielding member provided around the partition member;a first space inside the shielding member formed between the target and the partition member;a second space inside the shielding member formed between the substrate and the partition member;a sputter gas supply port for supplying the sputter gas to the first space inside the shielding member;an exhaust passage for exhausting at least part of the sputter gas from the first space inside the shielding member without passing through the plurality of openings;a reactive gas supply port for supplying the reactive gas to the second space inside the shielding member; andan exhaust passage for exhausting at least part of the reactive gas from the second space inside the shielding member without passing through the plurality of openings.
