Abstract (en)
[origin: WO9907515A1] Polishing pads are provided having a polishing surface formed from a hydrophilic material. The polishing surface has a topography produced by a thermoforming process. The topography consists of large and small features that facilitate the flow of polishing fluid and facilitate smoothing and planarizing.
