    摘要: Polishing pads with grooved foundation layers and polishing surface layers are described. In an example, a polishing pad for polishing a substrate includes a foundation layer having a pattern of grooves disposed therein. A continuous polishing surface layer is attached to the pattern of grooves of the foundation layer. In another example, a polishing pad for polishing a substrate includes a foundation layer with a surface having a pattern of protrusions disposed thereon. Each protrusion has a top surface and sidewalls. A non-continuous polishing surface layer is attached to the foundation layer and includes discrete portions. Each discrete portion is attached to the top surface of a corresponding one of the protrusions of the foundation layer. Methods of fabricating polishing pads with a polishing surface layer bonded to a grooved foundation layer are also described.
