    摘要: Embodiments of the present invention provide apparatus and method for front side protection while processing side and backside of a substrate. One embodiment of the present invention provides a showerhead configured to provide a purge gas to a front side of a substrate during a backside etch processing. The showerhead comprises a body configured to be disposed over the front side of the substrate. The body has a process surface configured to face the front side of the substrate. The process surface has an outer circular region, a central region, a middle region between the outer central region and the central region. The first plurality of holes are distributed in the outer circular region and configured to direct the purge gas towards an edge area of the front side of the substrate. No gas delivery hole is distributed within a substantial portion of the middle region.

    摘要: A flow equalizer plate is provided for use in a substrate process chamber. The flow equalizer plate has an annular shape with a flow obstructing inner region, and a perforated outer region that permits the passage of a processing gas, but retains specific elements in the processing gas, such as active radicals or ions. The inner and outer regions have varying radial widths so as to balance a flow of processing gas over a surface of a substrate. In certain embodiments, the flow equalizer plate may be utilized to correct chamber flow asymmetries due to a lateral offset of an exhaust port relative to a center line of a substrate support between the process volume and the exhaust port.
