Abstract:
1. A magnetron sputtering apparatus comprising: a substrate holder that can hold a substrate; a magnetron cathode having a cathode on which a target can be mounted, and a magnetic field generating apparatus; a high frequency power supply that applies high frequency power to the target; a first direct current power supply that applies direct current power to the target; a blocking capacitor placed between the high frequency power supply and the target; a low frequency cut filter placed between the blocking capacitor and the target, the low frequency cut filter cutting low frequency components of 0.01 MHz or less from the high frequency power supply so as to enlarge single-crystal domains, wherein one end of the low frequency cut filter is connected to the blocking capacitor and the other end of the low frequency cut filter is connected to the target; and a second direct current power supply that applies direct current power to the substrate holder, wherein parallel magnetic field strength (in gauss) on a surface of the substrate is set to 0.1 times or less parallel magnetic field strength (in gauss) on a surface of the target, and the parallel magnetic field strength on the surface of the target is set to 200 gauss or more and 1000 gauss or less.
