Abstract:
A method and apparatus for polishing a thin film formed on a semiconductor substrate. A table covered with a polishing pad is orbited about an axis. Slurry is fed through a plurality of spaced-apart holes formed through the polishing pad to uniformly distribute slurry across the pad surface during polishing. A substrate is pressed face down against the orbiting pad's surface and rotated to facilitate, along with the slurry, the polishing of the thin film formed on the substrate.
