Abstract:
The sputtering cathode has a tubular shape having a pair of long sides facing each other in cross-sectional shape, has a sputtering target whose erosion surface faces inward, and a magnetic circuit is provided along the sputtering target. The pair of long sides are constituted by rotary targets each having a cylindrical shape. The rotary target is internally provided with a magnetic circuit and configured to allow the flow of cooling water. The magnetic circuit is provided parallel to the central axis of the rotary target and has a rectangular cross-sectional shape having a long side perpendicular to the radial direction of the rotary target.

Claim (Index 1):
A sputtering cathode having a sputtering target, the cross-sectional shape of which is tubular or annular, having a pair of mutually facing long-side portions and a pair of mutually facing short-side portions, and having an erosion surface facing inward, a magnetic circuit being provided along the sputtering target, the sputtering cathode being characterized in that:\n the pair of long-side portions are formed as mutually parallel flat plates; the pair of short-side portions are formed as plates continuous with the pair of long-side portions; and at least one of short-side portions in the pair of short-side portions is curved, forming a curved surface in which the erosion surface is twisted from the one long-side portion side of the pair of long-side portions, a shape resulting in the central portion of the one short-side portion which is perpendicular to the pair of long-side portions, and is further curved, forming a curved surface in which the erosion surface is twisted, having a shape extending to the other long-side portion of the pair of long-side portions.
