摘要: A polishing pad has a polishing layer and a backing layer secured to the polishing layer. The polishing layer has a polishing surface, a first thickness, a first compressibility, and a hardness between about 40 to 80 Shore D. The backing layer has a second thickness and has a second compressibility greater than the first compressibility. The first thickness, first compressibility, second thickness and second compressibility are such that the polishing surface deflects more than the thickness non-uniformity of the polishing layer under an applied pressure of 1.5 psi or less.

摘要: A method and apparatus are provided for polishing a substrate surface. In one aspect, an apparatus for polishing a substrate includes a basin and a polishing head. A carrier is disposed in the basin and has a substrate supporting surface. A retaining ring is disposed on the carrier and at least partially circumscribes the substrate supporting surface. The polishing head is supported above the basin and includes a conductive polishing pad. Embodiments may further include a vent to allow gas to escape through the polishing head. Embodiments may further include an electrolyte supply that flows electrolyte into the polishing head and out through a permeable electrode and the conductive pad to the substrate. Embodiments may also be configured with a polishing head diameter smaller than the substrate supported by the carrier.
