Patent ID: 8900426

Claim:
A sputtering apparatus comprising: a target holder configured to hold a plurality of targets including first and second targets; a substrate holder configured to hold a substrate; a first shutter plate arranged between the target holder and the substrate holder, the first shutter plate having first and second holes and being capable of rotating around an axis; and a second shutter plate arranged between the first shutter and the substrate holder, the second shutter plate having third and fourth holes and being capable of rotating around the axis; wherein the first shutter plate and the second shutter plate are constructed such that when the first and second shutter plates are rotated into a first position the first hole and the third hole are in alignment with the first target and the second hole and the fourth hole are in alignment with the second target so as to simultaneously create a first path for the first target and a second path for the second target when a film is formed on the substrate by co-sputtering of the first and second targets, the first path being created between the first target and the substrate through the first hole and the third hole, the second path being created between the second target and the substrate through the second hole and the fourth hole; and the sputtering apparatus further comprising a controller for controlling rotation of the first and second shutter plates into the first position such that the first and second paths are simultaneously created between the at least two targets and the substrate, and for forming a film on the substrate by co-sputtering of the at least two targets.
