Abstract (en)

[origin: EP0923122A2] 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 (e.g., 130) coupled to a ring member (e.g., 120) that contacts a substrate (e.g., 200) during the CMP process. The present invention also provides a carrier fixture having inner (e.g., 130) and outer supports (e.g., 125) coupled to a ring member (e.g., 120). <IMAGE>
