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 30):
A method for producing a film-formed body, comprising:\n providing a sputtering device constructed in accordance with  claim 18  within a sputtering chamber; introducing a sputtering gas into the interior region of the sputtering target; applying a voltage between the anode and the sputtering cathode sufficient to generate a plasma of the sputtering gas, which plasma causes the different species of sputtering atoms of the sputtering erosion surfaces to be emitted from one of the open ends of the sputtering target, the plasma being confined to regions within the interior region of the sputtering target that are adjacent to the erosion surfaces; moving the moveable shield into a first position to block a first one of the different species of sputtering atoms; moving the to-be-coated substrate past said one of the open ends of the sputtering target in a first direction, transverse to the lengthwise direction of the sputtering target and with the moveable shield disposed between the to-be-coated substrate and said one of the open ends of the sputtering target, so that a first film comprised of a second one of the different species of emitted atoms is formed on the to-be-coated substrate, the substrate not being contacted by the plasma; not being passed through the lines of magnetic force forming the magnetic circuit; and not being exposed to light and not being exposed to electron beam radiation attributable to the plasma; moving the moveable shield into a second position to block the second one of the different species of sputtering atoms; and moving the to-be-coated substrate past said one of the open ends of the sputtering target in a second direction that is opposite to the first direction and that is transverse to the lengthwise direction of the sputtering target, with the moveable shield being disposed between the to-be-coated substrate and said one of the open ends of the sputtering target, so that a second film comprised of the first one of the different species of emitted atoms is formed on the substrate on top of the first film, the substrate not being contacted by the plasma; not being passed through the lines of magnetic force forming the magnetic circuit; and not being exposed to light and not being exposed to electron beam radiation attributable to the plasma.
