Abstract:
A thin film forming apparatus comprising a substrate holder for holding a substrate, a target holder for holding a target, a sputter gas supply means for supplying into a reaction chamber a sputter gas for sputtering the target, a reactive gas supply means for supplying a reactive gas:a partition member having a plurality of openings provided between the target and the substrate, and each of the openings has an aspect ratio of less than 0.6; and a sputter gas supply port and a reactive gas supply port separately provided at a distance from each other so that the sputter gas is supplied to a space formed between the target and the partition member and the reactive gas is supplied to a space formed between the substrate and the partition member; wherein a diameter of each of the openings is 1% to 15% of a diameter of the substrate, such that a pressure in a space on the target side is larger than a pressure in a space on the substrate side.
