An apparatus and method for performing chemical-mechanical polishing is disclosed in which the pad is secured to the platen without the use of adhesives. A polishing pad and a platen are secured together by a releasable attractive force; the force may comprise a vacuum or electromagnetic force, and the pad has a hard or magnetic backside layer for facing the plating and responding to the attractive force. This invention has particular application to chemical-mechanical polishing for use in planarizing dielectrics.

Method for performing chemical-mechanical polishing

Apparatus for performing chemical-mechanical polishing

A method of manufacturing integrated circuits using a carrier fixture. The carrier fixture does not include transport channels or openings for directing a slurry to a substrate being polished and, as a result, damage to the substrate is reduced because the edges adjacent to the substrate are eliminated. The present invention further provides a carrier fixture having an inner support coupled to a ring member that contacts a substrate during the CMP process. The present invention also provides a carrier fixture having inner and outer supports coupled to a ring member.
