Abstract (en)

[origin: WO0187541A2] An apparatus and method for planarizing a substrate are provided. The apparatus (101) includes a carrier (106) having: a plate (261) for receiving the substrate (230) thereon; a first chamber (297) for forcing the plate in a predetermined direction; a spacer (260) coupled to an outer edge (282) of the plate; a membrane (250) coupled to the plate via the spacer and separated from the plate by a thickness of the spacer; and a second chamber (298) defined between the membrane and the plate for forcing the membrane in another predetermined direction. The method involves pressing a peripheral edge of the substrate (113) against a polishing pad (135) with a first pressure, and pressing an interior of the substrate against the pad with a second pressure. The first pressure may be provided through a mechanical contact with the peripheral edge of the substrate (113), a pneumatic pressure exerted through a membrane (250), or by gas pressing directly against a portion of the substrate.
