Abstract: Methods of semiconductor processing may include forming a plasma of a carbon-containing material within a processing region of a semiconductor processing chamber. The methods may include depositing a carbon-containing material on a backside of a substrate housed within the processing region of the semiconductor processing chamber. A front side of the substrate may be maintained substantially free of carbon-containing material. The methods may include performing an etch process on the front-side of the substrate. The methods may include removing the carbon-containing material from the backside of the substrate.
