    Abstract: Implementations of the present disclosure generally relate to hardmask films and methods for depositing hardmask films. More particularly, implementations of the present disclosure generally relate to tungsten carbide hardmask films and processes for depositing tungsten carbide hardmask films. In one implementation, a method of forming a tungsten carbide film is provided. The method comprises forming a tungsten carbide initiation layer on a silicon-containing surface of a substrate at a first deposition rate. The method further comprises forming a tungsten carbide film on the tungsten carbide initiation layer at a second deposition rate, wherein the second deposition rate is greater than the first deposition rate.

    Abstract: A method and apparatus for operating a plasma processing chamber includes performing a plasma process at a process pressure and a pressure power to generate a plasma. A first ramping-down stage starts in which the process power and the process pressure are ramped down substantially simultaneously to an intermediate power level and an intermediate pressure level, respectively. The intermediate power level and intermediate pressure level are preselected so as to raise a plasma sheath boundary above a threshold height from a surface of a substrate. A purge gas is flowed from a showerhead assembly at a sufficiently high rate to sweep away contaminant particles trapped in the plasma such that one or more contaminant particles move outwardly of an edge of the substrate. A second ramping-down stage starts where the intermediate power level and the intermediate pressure level decline to a zero level and a base pressure, respectively.

    Abstract: Implementations of the present disclosure generally relate to an apparatus for reducing particle contamination on substrates in a plasma processing chamber. The apparatus for reduced particle contamination includes a chamber body, a lid coupled to the chamber body. The chamber body and the lid define a processing volume therebetween. The apparatus also includes a substrate support disposed in the processing volume and an edge ring. The edge ring includes an inner lip disposed over a substrate, a top surface connected to the inner lip, a bottom surface opposite the top surface and extending radially outward from the substrate support, and an inner step between the bottom surface and the inner lip. To avoid depositing the particles on the substrate being processed when the plasma is de-energized, the edge ring shifts the high plasma density zone away from the edge area of the substrate.

    Abstract: A method and apparatus for heating a substrate in a chamber are provided. an apparatus for positioning a substrate in a processing chamber. In one embodiment, the apparatus comprises a substrate support assembly having a support surface adapted to receive the substrate and a plurality of centering members for supporting the substrate at a distance parallel to the support surface and for centering the substrate relative to a reference axis substantially perpendicular to the support surface. The plurality of the centering members are movably disposed along a periphery of the support surface, and each of the plurality of centering members comprises a first end portion for either contacting or supporting a peripheral edge of the substrate.
