Abstract

A sealing structure is between a workpiece or substrate and a carrier for plasma processing. In one example, a substrate carrier has a top surface for holding a substrate, the top surface having a perimeter and a resilient sealing ridge on the perimeter of the top surface to contact the substrate when the substrate is being carried on the carrier.
