Methods for pressure ramped plasma purge

Exemplary deposition methods may include forming a plasma of a silicon-containing precursor and at least one additional precursor within a processing region of a semiconductor processing chamber. The processing region may house a semiconductor substrate on a substrate support. The methods may includ...

Zusammenfassung:Exemplary deposition methods may include forming a plasma of a silicon-containing precursor and at least one additional precursor within a processing region of a semiconductor processing chamber. The processing region may house a semiconductor substrate on a substrate support. The methods may include depositing material on the semiconductor substrate to a target thickness. The methods may include halting delivery of the silicon-containing precursor while maintaining the plasma with the one or more precursors. The methods may include purging the processing region of the semiconductor processing chamber.
