Proximity contact cover ring for plasma dicing

Last updated:

Abstract:

Methods of and carriers for dicing semiconductor wafers, each wafer having a plurality of integrated circuits, are described. In an example, a cover ring for protecting a carrier and substrate assembly during an etch process includes an inner opening having a diameter smaller than the diameter of a substrate of the carrier and substrate assembly. An outer frame surrounds the inner opening. The outer frame has a bevel for accommodating an outermost portion of the substrate of the carrier and substrate assembly.
