Patent ID: 6863785

Claim:
A carousel sputtering apparatus which is configured so that a drum, which is formed in a polygonal or circular shape in transverse cross-section, is provided so as to be rotatable in a chamber, the drum having substrate holders provided on an outer peripheral surface; magnetron sputtering sources are provided inside a chamber wall; each of the magnetron sputtering sources comprises a target and a magnetron unit for holding the target; and the targets are held so as to be parallel with a rotary axis of the drum by the magnetron units; the sputtering apparatus comprising: a film thickness measuring instrument, which measures a thickness of a film deposited on a substrate mounted on one of said substrate holders during film deposition; a power supply unit, which supplies the respective targets with power required for sputtering; and a controller, which controls parameters affecting on an amount of film deposition, based on measurement results obtained by the film thickness measuring instrument, wherein each of the magnetron sputtering sources comprises an AC magnetron sputtering source and a magnetron sputtering source with a target mounted on a single magnetron unit, and the AC magnetron sputtering source having two adjacent targets provided thereon such that an anode/cathode relationship between the two targets is alternately changed by a frequency.
