    Abstract: A method and apparatus for determining particle contamination of a process fluid is disclosed herein. In one example, a fluid resistivity measurement probe is provided. The system includes an upstream fluid conduit, a downstream fluid conduit, and a measuring section. The measuring section has a metal rod, and a ground electrode. The ground electrode surrounds and is coaxial with the metal rod. The upstream fluid conduit is coupled to a first end of the ground electrode. The downstream fluid conduit is coupled to a second end of the ground electrode. The metal rod and the ground electrode define a space therebetween. The space flows a fluid from the upstream fluid conduit to the downstream fluid conduit.

    Abstract: Disclosed herein is a processing system. The processing system has an upper chamber body and a lower chamber body defining a processing environment. An upper heater is moveably disposed in the upper chamber body. The upper heater has a moveable support and an upper step formed along an outer perimeter. A lower showerhead is fixedly disposed in the lower chamber body. The lower showerhead includes a top surface configured to support a substrate, a lower step disposed along an outer perimeter wherein the substrate is configured to extend from the top surface partially over the lower step. Lift pins are disposed in the lower showerhead and configured to extend through the top surface and support the substrate thereon. Gas holes are disposed in a first zone along the top surface and a second zone on the step and configured to independently flow both a process and non-process gas.
