Non-Contact Polishing.
Abstract
A non-contact polishing apparatus is used for polishing semiconductor planar substrates. The substrate is set back from any surface and is held by a chuck fixed within a collar. This substrate holder assembly is placed within an enclosed container that has a non-abrasive solution therein. The container is mounted to a high speed nutating table that provides random motion to the holder assembly. This action provides isotropic polishing with no polishing created defects on the substrate surface.
