Patent ID: 8168049

Claim:
A sputtering apparatus, wherein a conveying path for conveying a substrate is disposed in a sputtering chamber to which an exhaust device is connected; a first cathode for holding a first target which is obliquely opposed toward a front in the conveying direction of the substrate and a second cathode for holding a second target which is obliquely opposed toward a back in the conveying direction of the substrate are arranged to obliquely face the conveying path; a first shield on a side of the first cathode and a second shield on a side of the second cathode opposed to the conveying direction of the substrate are disposed between the conveying path and the first and second cathodes to have therebetween an extended region toward the conveying path in a space between the first target and the second target; and an end of the first shield on the side of the conveying path is present over a point where a vertical line to a second target surface erected on an end of the second target on the side of the conveying path intersects with the first shield and an end of the second shield on the side of the conveying path is present over a point where a vertical line to a first target surface erected on an end of the first target on the side of the conveying path intersects with the second shield.
