Removal of process residues on the backside of a substrate |
摘要 |
<p>A substrate is processed in a process chamber comprising a substrate support having a receiving surface for receiving a substrate so that a front surface of the substrate is exposed within the chamber. An energized process gas is used to process the front surface of the substrate. A peripheral edge of the backside surface of the substrate is cleaned by raising the substrate above the receiving surface of the substrate support to a raised position, and exposing the backside surface of the substrate to an energized cleaning gas.
