  • Publication number: 20090134011
    Abstract: For producing a directional layer for instance with constant nominal directionality, such as a low-retentivity layer with a preferred direction of magnetization or a support layer for such a layer by cathode sputtering on a substrate surface (4), the coating process takes place in a manner whereby particles emanating from a target surface (6) impinge predominantly from directions at which their projection onto the substrate surface (4) lies within a preferred angular range surrounding the nominal direction. This is achieved for instance by positioning a collimator (8), encompassing plates (9) that extend at a normal angle to the substrate surface (4) parallel to the nominal direction in front of the substrate surface (4), but in lieu of or in addition to such positioning the location or movement of the substrate surface (4) relative to the target surface (6) can also be suitably adjusted or controlled.

  • Publication number: 20090111216
    Abstract: A method of magnetically enhanced sputtering an electrically-conductive material onto interior surfaces of a trench described herein includes providing a magnetic field adjacent to a target formed at least in part from the electrically-conductive material, and applying a DC voltage between an anode and the target as a plurality of pulses. A high-frequency signal is applied to the pedestal supporting the semiconductor substrate to generate a self-bias field adjacent to the semiconductor substrate. The high-frequency signal is applied to the pedestal in pulses, during periods of time that overlap with the periods during which the DC voltage pulses are applied. The periods of time that the high-frequency signals are applied include a duration that extends beyond termination of the DC voltage pulse applied between the anode and the target. During each DC voltage pulse the electrically-conductive material is sputter deposited onto the side walls of the trench formed in the semiconductor substrate.

  • Patent number: 7429543
    Abstract: Method for producing a substrate includes establishing a plasma discharge with a locally inhomogeneous density distribution and exposing the substrate to the inhomogeneously density-distributed plasma discharge. The distribution is established by establishing a specified relative movement of the inhomogeneous density distribution and of the substrate and establishing a specified time variation of an electric power signal supplying the discharge and/or of an optionally provided further electric signal which connects the substrate to bias voltage. When the electric power signal or further electric signal is an AC signal, the specified time variation of the signal addresses its modulation and the method includes setting the variation and the movement.

  • Publication number: 20070175748
    Abstract: Sputtering is performed by making use of a stationary magnetic field (Hs). Uneroded areas of the sputtering surface (3) which are subject to re-deposition are minimized or omitted by modulating the stationary magnetic field (Hs) adjacent to one of the magnetic poles responsible for the stationary magnetic field, by superimposing a modulating magnetic field (Hm) to said stationary field (Hs).

  • Publication number: 20050199485
    Abstract: A magnetron source, a magnetron treatment chamber, and a method of manufacturing substrates with a vacuum plasma treated surface, generate and exploit on asymmetrically unbalanced long-range magnetron magnetic field pattern which is swept along the substrate surface for improving the ion density at a substrate surface being vacuum plasma treated. The long-range field reaches the substrate surface with a component of the magnetic field parallel to the substrate surface of at least 0.1, and preferably between 1 and 20, Gauss. The plasma treating can be sputter-coating, or etching, for example.

  • Patent number: 6860977
    Abstract: A workpiece is manufactured using a magnetron source that has an optimized yield of sputtered-off material as well as service life of the target.

  • Patent number: 5234560
    Abstract: A method and apparatus for controlling thin layer sputtering, especially titanium-nitride-type hard, abrasion-proof layers. Ionization current on substrates, especially at greater distances from cathode, is increased and layers are more homogenous. Density and homogeneity of both ionization and electron current on substrates are increased and ionic cladding during layer sputtering and with floating potential of substrates is possible. Substrates are placed in a holding space defined by lines of force of a magnetic multipolar field that includes a closed tunnel of magnetron-type lines of force above the sputtered cathode and whose direction on the boundary of the holding space alternates from positive to negative polarity and vice versa. In the holding space, interaction of the glow discharge with the magnetic multipolar field forms a homogenous plasma whose particles bombard the substrates.
