Abstract: Planarizing machines, carrier heads for planarizing machines and methods for planarizing microelectronic-device substrate assemblies in mechanical or chemical-mechanical planarizing processes. In one embodiment of the invention, a carrier head includes a backing plate, a bladder attached to the backing plate, and a retaining ring extending around the backing plate. The backing plate has a perimeter edge, a first surface, and a second surface opposite the first surface. The second surface of the backing plate can have a perimeter region extending inwardly from the perimeter edge and an interior region extending inwardly from the perimeter region. The perimeter region, for example, can have a curved section extending inwardly from the perimeter edge of the backing plate or from a flat rim at the perimeter edge. The curved section can curve toward and/or away from the first surface to influence the edge pressure exerted against the substrate assembly during planarization.

Abstract: The invention encompasses polishing systems for polishing semiconductive material substrates, and encompasses methods of cleaning polishing slurry from semiconductive substrate surfaces. In one aspect, the invention includes a method of cleaning a polishing slurry from a substrate surface comprising: a) providing a substrate surface having a polishing slurry in contact therewith; b) providing a liquid; c) injecting a gas into the liquid to increase a total dissolved gas concentration in the liquid; and d) after the injecting, providing the liquid against the substrate surface to displace the polishing slurry from the substrate surface.
