Abstract
An article includes a polishing layer that includes a plurality of raised cells separated by a plurality of channels. Each of the plurality of raised cells includes a microstructured working surface, a substantially vertical channel surface, and an offset surface between an edge of the working surface and an upper edge of the channel surface. The microstructured working surface includes a plurality of microstructures. Tops of the plurality of microstructures define a top plane and bases of the plurality of microstructures define a base plane. The substantially vertical channel surface defines a wall of a channel of the plurality of channels and the channel surface defines a channel plane. The offset surface includes a nonplanar portion of displaced material. The displaced material defines a displacement plane that is below the base plane or within a tolerance of the top plane.
