    摘要: Embodiments of the present invention generally relates to apparatus for use in film depositions. The apparatus generally include pre-heat rings adapted to be positioned in a processing chamber. In one embodiment, a pre-heat ring includes a ring having an inner edge and an outer edge. The outer edge has a constant radius. The inner edge is oblong-shaped and may have a first portion having a constant radius measured from a center of a circle defined by an outer circumference of the ring. A second portion may have a constant radius measured from a location other than the center of the outer circumference. In another embodiment, a processing chamber includes a pre-heat ring positioned around the periphery of a substrate support. The pre-heat ring includes an inner edge having a first portion, a second portion, and one or more linear portions positioned between the first portion and the second portion.

    摘要: In a first aspect, a method is provided for forming an epitaxial layer stack on a substrate. The method includes (1) selecting a target carbon concentration for the epitaxial layer stack; (2) forming a carbon-containing silicon layer on the substrate, the carbon-containing silicon layer having at least one of an initial carbon concentration, a thickness and a deposition time selected based on the selected target carbon concentration; and (3) forming a non-carbon-containing silicon layer on the carbon-containing silicon layer prior to etching. Numerous other aspects are provided.
