Abstract: An apparatus for sputter deposition of material on a substrate. The apparatus includes a deposition chamber and a cathode array mounted in the deposition chamber. The array has three or more rotating cathodes. Each cathode has a cylindric target of equal target length LT and a magnetic system. The cathodes are spaced from one another such that their longitudinal axes YCj are arranged parallel to each other, in a distance TSD from a substrate plane S, and spaced apart along a projection of a substrate axis X in a distance TTT, whereat each cathode of the cathode array includes a magnetic system. The magnetic system of at least one cathode is swivel mounted round respective cathode axis YCj to swivel the magnetic system into and out of a swivel plane PTS. A pedestal is designed to support at least one substrate of maximal dimensions x*y to be coated in a static way. The pedestal is positioned in the deposition chamber in front of and centered with reference to the cathode array.

Abstract: A plasma etching chamber including within a vacuum recipient: an etching compartment with a central axis and a surrounding wall enclosing the etching compartment; a pumping compartment with a metal surrounding wall having a feed through opening; a metal partition wall traverse to the axis separating the etching compartment from the pumping compartment; a pumping slit in or along the partition wall; a workpiece support; a metal tubular arrangement through the opening, including a first part coupled to the workpiece support and a second part coupled to the metal surrounding wall, the second part being electrically conductively joint to the metal surrounding wall; an Rf feed line through the tubular arrangement connected to the workpiece support; a system ground connector at an end of the second part; distributed metal connectors establishing electric contact from the metal surrounding wall, across the pumping slit via the partition wall to the first part.

Abstract: A method and apparatus for sputter depositing an insulation layer onto a surface of a cavity formed in a substrate and having a high aspect ratio. A target formed from a material to be included in the insulation layer and the substrate are provided in a substantially enclosed chamber defined by a housing. A plasma is ignited within the substantially enclosed chamber and a magnetic field is provided adjacent to a surface of the target to contain the plasma adjacent to the surface of the target. A voltage is rapidly increased to repeatedly establish high-power electric pulses between a cathode and an anode. An average power of the electric pulses is at least 0.1 kW, and can be much greater. An operational parameter of the sputter deposition is controlled to promote sputter depositing of the insulation layer in a transition mode between a metallic mode and a reactive mode.

Abstract: A method and apparatus for sputter depositing an insulation layer onto a surface of a cavity formed in a substrate and having a high aspect ratio is provided. A target formed at least in part from a material to be included in the insulation layer and the substrate are provided in a substantially enclosed chamber defined by a housing. A plasma is ignited within the substantially enclosed chamber and a magnetic field is provided adjacent to a surface of the target to at least partially contain the plasma adjacent to the surface of the target. A voltage is rapidly increased to repeatedly establish high-power electric pulses between a cathode and an anode. An average power of the electric pulses is at least 0.1 kW, and can optionally be much greater. An operational parameter of the sputter deposition is controlled to promote sputter depositing of the insulation layer in a transition mode between a metallic mode and a reactive mode.

Abstract: Apparatus for depositing a layer on a substrate in a process gas includes a chuck containing a first surface for supporting the substrate, a clamp for securing the substrate to the first surface of the chuck, an evacuatable enclosure enclosing the chuck and the clamp and control apparatus. The evacuatable enclosure includes an inlet, through which the processing gas is insertable into the enclosure. The control apparatus is adapted to move at least one of the chuck and the clamp relative to, and independently of, one another to adjust a spacing between the chuck and the clamp during a single deposition process while maintaining a flow of the processing gas and a pressure within the enclosure that is less than atmospheric pressure.

Abstract: A method of depositing a metallization structure (1) comprises depositing a TaN layer (4) by applying a power supply between an anode and a target in a plurality of pulses to reactively sputter Ta from the target onto the substrate (2) to form a TaN seed layer (4). A Ta layer (5) is deposited onto the TaN seed layer (4) by applying the power supply in a plurality of pulses and applying a high-frequency signal to a pedestal supporting the substrate (2) to generate a self-bias field adjacent to the substrate (2).

Abstract: A method of pulsed bipolar sputtering including applying a sputtering pulse (?) during a first period of time (T?) and applying a revers voltage pulse during a subsequent second period of time (T+). The step of applying the revers voltage pulse comprises controlling, in particular adjusting, the timing of the revers voltage pulse (T+). This way high quality sputtering is achieved, in particular for sputtering temperature sensitive materials.
