    摘要: A magnet assembly for producing a varying magnetic field is provided wherein a plurality of permanent magnets are interposed between two members which are constructed of a ferromagnetic material. Each of the magnets is rotatable and has a north and south magnetic pole. Each of the magnets is disposed so that the north magnetic poles of the plurality of permanent magnets have a common magnetic orientation with respect to the first member. An orienter, such as, for example, a ring gear and pinion arrangement, is coupled to the magnets to change their common magnetic orientation with respect to the first member. The magnetic field projected by the assembly varies as a function of the orientation of the magnets.

    摘要: In conjunction with sputtering a metal, especially copper, into high aspect-ratio holes in a wafer, an oblique ion milling method in which argon ions or other particles having energies in the range of 200 to 1500 eV are directed to the wafer at between 10 and 35null to the wafer surface to sputter etch material sputter deposited preferentially on the upper corners of the holes. The milling may be performed in the sputter deposition chamber either simultaneously with the deposition or after it or performed afterwards in a separate milling reactor. A plurality of ion sources arranged around the chamber improve angular uniformity or arranged axially improve radial uniformity or vary the angle of incidence. An annular ion source about the chamber axis allows a plasma current loop. Anode layer ion sources and sources composed of copper are advantageous.

    摘要: Methods and apparatuses for shielding magnetic flux which is associated with a semiconductor fabrication system are provided. A magnetic shield assembly substantially surrounds a side wall of a plasma reactor. The shield assembly comprises a passive shield member in combination with an active shield member. As a result, effective shielding of magnetic flux can occur without excessive distortion of the magnetic field line pattern in the plasma region of the plasma reactor. In one aspect, the shield assembly comprises a first shield member adapted to attenuate a magnetic flux density. The first shield member is disposed in a parallel, spaced apart relationship from the side wall. A second member is attached to the first shield member and is constructed of a ferromagnetic material which is permanently magnetized.

    摘要: A source of sputtered deposition material has, in one embodiment, a torus-shaped plasma generation area in which a plasma operates to sputter the interior surface of a toroidal cathode. In one embodiment, the sputtered deposition material passes to the exterior of the source through apertures provided in the cathode itself. A torus-shaped magnetic field generated in the torus-shaped plasma facilitates plasma generation, sputtering of the cathode and ionization of the sputtered material by the plasma.
