摘要： Low density polishing pads and methods of fabricating low density polishing pads are described. In an example, a polishing pad for polishing a substrate includes a polishing body having a density approximately in the range of 0.4-0.55 g/cc. The polishing body includes a thermoset polyurethane material and a plurality of closed cell pores dispersed in the thermoset polyurethane material. Each of the plurality of closed cell pores has a shell composed of an acrylic co-polymer.

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.
