Chamber deposition and etch process

Abstract:

Exemplary methods of semiconductor processing may include depositing a material on a substrate seated on a substrate support housed in a processing region of a semiconductor processing chamber. The processing region may be at least partially defined by the substrate support and a faceplate. The substrate support may be at a first position within the processing region relative to the faceplate. The methods may include translating the substrate support to a second position relative to the faceplate. The methods may include forming a plasma of an etchant precursor within the processing region of the semiconductor processing chamber. The methods may include etching an edge region of the substrate.
