Abstract:
Embodiments of the invention provide a single ring comprising a circular ring-shaped body with an inner surface, closest in proximity to a centerline of the body, and an outer surface opposite the inner surface. The body has a bottom surface with a slot formed therein and a top surface with an outer end, adjacent to the outer surface, and an inner end adjacent to a slope extending, towards the centerline, down to a step on the inner surface. The body has a lip, disposed on the inner surface extending out from a vertical face below the step toward the centerline of the body, and is configured to support a substrate thereon. The body is sized such that a gap of less than about 2 mm is formed on the lip between the substrate and the vertical face of the step.
Abstract:
Methods for performing post etch treatments on silicon surfaces etched using halogen chemistry are provided. The methods may be performed in-situ a chamber in which the silicon surfaces where etch, ex-situ the chamber, or in a hybrid process that combines both in-situ and ex-situ post etch treatment processes. In one embodiment the post etch treatment process includes exposing a substrate having a silicon surface etched using halogen chemistry to a gas mixture comprising CxHy and oxygen, wherein x and y are integers, forming a plasma from the gas mixture, binding halogen residues with species comprising the plasma to form non-volatile halogen containing elements, and pumping the non-volatile halogen containing elements from a chamber containing the substrate.
