  • Publication number: 20050252454
    Abstract: A lifting assembly can lift a substrate from a substrate support and transport the substrate. The lift assembly has a hoop sized to fit about a periphery of the substrate support, and a pair of arcuate fins mounted on the hoop, each arcuate fin comprising a pair of opposing ends having ledges that extend radially inward, each ledge having a raised protrusion to lift a substrate so that the substrate contacts substantially only the raised protrusion, thereby minimizing contact with the ledge, when the pair of fins is used to lift the substrate off the substrate support. The lifting assembly and other process chamber components can have a diamond-like coating having interlinked networks of (i) carbon and hydrogen, and (ii) silicon and oxygen. The diamond-like coating has a contact surface having a coefficient of friction of less than about 0.3, a hardness of at least about 8 GPa, and a metal concentration level of less than about 5×1012 atoms/cm2 of metal.

  • Patent number: 5658442
    Abstract: The disadvantages heretofore associated with the prior art are overcome by the present invention of an improved target for a physical deposition (PVD) system. The improved target has a portion of the target side wall the overhangs and shadows the side wall of the target thus preventing material from depositing on the edge. To further reduce contaminant generation, the improved target is combined with an improved dark space shield having a first end and a second end, where the second end conventionally supports a collimator and the first end has an inner surface that is substantially vertical.
