Abstract
An abrasive article for polishing a substrate surface. The abrasive article includes a holder pad assembly and an abrasive member held in place with respect to a holder pad. The abrasive member further includes a first surface engaged with the holder pad assembly, and a second surface including an abrasive. A preload mechanism is positioned to bias the second surfaces of the abrasive member toward the substrate surface. One or more fluid bearing features on the second surface of the abrasive member is configured to generate lift forces during relative motion between the abrasive article and the substrate surface.
