Abstract:
A planarizing machine, comprising:a table with a stationary support base;a processing medium attached to the stationary support base, the processing medium having a planarizing section and finishing section proximate to the planarizing section, the planarizing section extending lengthwise along the processing medium and having a first body composed of a first material and a relatively firm planarizing surface, the first body supporting abrasive particles at the planarizing surface to remove material from a substrate during a planarizing cycle, and the finishing section extending lengthwise along the processing medium and having a second body composed of a second material and a buffing surface softer than the planarizing surface to clean the substrate during a finishing cycle, the planarizing and finishing sections being abutted against one another along a boundary extending longitudinally along the processing medium; anda carrier assembly having at least a first substrate holder positionable over the stationary processing medium, the first substrate holder translating the substrate over the planarizing section during the planarizing cycle, and the first substrate holder moving the substrate to the finishing section at the same work-station and translating the substrate over the finishing section in the presence of a cleaning fluid during the finishing cycle.
