Abstract:
This sputtering cathode has a sputtering target having a tubular shape in which the cross-sectional shape thereof has a pair of long side sections facing each other, and an erosion surface facing inward. Using the sputtering target, while moving a body to be film-formed, which has a film formation region having a narrower width than the long side sections of the sputtering target, parallel to one end face of the sputtering target and at a constant speed in a direction perpendicular to the long side sections above a space surrounded by the sputtering target, discharge is performed such that a plasma circulating along the inner surface of the sputtering target is generated, and the inner surface of the long side sections of the sputtering target is sputtered by ions in the plasma generated by a sputtering gas to perform film formation in the film formation region of the body to be film-formed.

Claim (Index 11):
A sputtering device, comprising:\n an anode; and a sputtering cathode, comprising a sputtering target having a tubular configuration that extends in a lengthwise direction with a rectangular cross-section taken transverse to the lengthwise direction, the sputtering target having an open end at each end thereof, the sputtering target comprising a pair of major side walls that extend in the lengthwise direction of the sputtering target and that oppose each other across an interior region of the sputtering target, with opposing inner surfaces of the major side walls constituting sputtering erosion surfaces; a pair of permanent magnets disposed near outer surfaces of each of the major side walls of the sputtering target with one magnet disposed toward each open end of the sputtering target, wherein 1) the north pole of one permanent magnet of the pair faces toward the sputtering target and the south pole of said one permanent magnet of the pair faces away from the sputtering target; and 2) the south pole of the other permanent magnet of the pair faces toward the sputtering target and the north pole of said other permanent magnet of the pair faces away from the sputtering target; and a yoke extending between and magnetically connecting the away-facing poles of the pair of permanent magnets; whereby the pair of permanent magnets and the yoke form a magnetic circuit, with lines of magnetic force extending from the north pole of said one permanent magnet of the pair; along a longitudinally central portion of the nearby one of the major side walls to the south pole of said other permanent magnet of the pair; through said other permanent magnet of the pair to the north pole of said other permanent magnet of the pair; and along the yoke back to the south pole of said one permanent magnet of the pair; wherein the anode is disposed near one of the open ends of the sputtering target and the sputtering device further comprises a shield disposed near the other open end of the sputtering target, the shield being configured and disposed to limit the emission of plasma-caused radiation out of the sputtering target from the open end near which the shield is disposed.
