COATED CARRIER FOR LAPPING AND METHODS OF MAKING AND USING

摘要

A lapping carrier (110) including a base carrier (112) having first and second major surfaces and at least one aperture for holding a workpiece extending from the first major surface to the second major surface, the aperture circumference defined by a third surface of the base carrier, at least a portion of the first and/or second major surfaces including a polymeric region having at least the following adhesion promoting layers: (a) a primer layer (116) including at least one of a phenolic resin or a novolac resin; (b) a tie layer(115) adjoining the primer layer(116), the tie layer(115) including at least one of an amino- functional epoxy resin or a hydroxyl- functional epoxy resin; and (c) a polymeric layer (114) adjoining the tie layer (115) on a side opposite the primer layer(116), the polymeric layer(116) including an isocyanate-functional polymer. Also described are methods of making and using the carrier.
