METHODS AND APPARATUS FOR PROCESSING A SUBSTRATE

Abstract:

Methods and apparatus for far edge trimming are provided herein. For example, an apparatus includes an integrated tool for processing a silicon substrate, comprising a vacuum substrate transfer chamber, an edge trimming apparatus coupled to the vacuum substrate transfer chamber and comprising a high pulse frequency laser and substrate support, wherein at least one of the high pulse frequency laser or the substrate support are movable with respect to each other and configured to trim about 2 mm to about 5 mm from a peripheral edge of a substrate when disposed on the substrate support, and a plasma etching apparatus coupled to the vacuum substrate transfer chamber and configured to etch silicon.
