Abstract:
Implementations disclosed herein describe a bevel etch apparatus within a loadlock bevel etch chamber and methods of using the same. The bevel etch apparatus has a mask assembly within the loadlock bevel etch chamber. During an etch process, the mask assembly delivers a gas flow to control bevel etch without the use of a shadow frame. As such, the edge exclusion at the bevel edge can be reduced, thus increasing product yield.
