  • Patent number: 8668816
    Abstract: A magnetron sputter reactor for sputtering deposition materials such as tantalum, tantalum nitride and copper, for example, and its method of use, in which self-ionized plasma (SIP) sputtering and inductively coupled plasma (ICP) sputtering are promoted, either together or alternately, in the same or different chambers. Also, bottom coverage may be thinned or eliminated by ICP resputtering in one chamber and SIP in another. SIP is promoted by a small magnetron having poles of unequal magnetic strength and a high power applied to the target during sputtering. ICP is provided by one or more RF coils which inductively couple RF energy into a plasma. The combined SIP-ICP layers can act as a liner or barrier or seed or nucleation layer for hole. In addition, an RF coil may be sputtered to provide protective material during ICP resputtering.

  • Publication number: 20140027274
    Abstract: A plasma processing apparatus is disclosed. The plasma processing apparatus includes a source configured to generate a plasma in a process chamber having a plasma sheath adjacent to the front surface of a workpiece, and a plasma sheath modifier. The plasma sheath modifier controls a shape of a boundary between the plasma and the plasma sheath so a portion of the shape of the boundary is not parallel to a plane defined by a front surface of the workpiece facing the plasma. A metal target is affixed to the back surface of the plasma sheath modifier so as to be electrically insulated from the plasma sheath modifier and is electrically biased such that ions exiting the plasma and passing through an aperture in the plasma sheath modifier are attracted toward the metal target. These ions cause sputtering of the metal target, allowing three dimensional metal deposition of the workpiece.

    Abstract: An arrangement for the separation of particles from plasma for the formation of a coating onto the surface of a substrate under vacuum conditions. The plasma is advantageously formed by electrical arc discharge. The plasma is formed from a target that can be connected as a cathode and positive charge carriers of the plasma are accelerated in the direction of a surface of a substrate to be coated by at least one absorber electrode connected to an electrical potential that is positive with respect to the plasma. The absorber electrode is arranged and orientated such that a direct incidence of plasma onto the absorber electrode is avoided and can be designed in plate form aligned at an obliquely inclined angle which takes account of the divergence of the plasma flow. In addition, at least one permanent magnet or electromagnet element is a component of the arrangement.
