  • Patent number: 8801949
    Abstract: The method forms forming an open-network polishing pad useful for polishing magnetic, semiconductor and optical substrates. The method provides a polymer sheet or film of a curable polymer and exposes the polymer sheet or film to an energy source to create an exposure pattern in the polymer sheet or film. The exposure pattern having elongated sections exposed to the energy source. After attaching the polymer sheet or film to an open-network substrate, the method removes polymer adjacent from the exposed polymer sheet or film of the intermediate structure with a solvent. This forms elongated channels through the polymer sheet or film in a texture pattern that corresponds to the exposure pattern with the open-network supporting the polymer. The elongated channels extending through the thickness of the polymer sheet or film to form the open-network polishing pad.
