  • Patent number: 9669512
    Abstract: Embodiments of the disclosure generally provides a method and apparatus for a polishing article or polishing pad having a microstructure that facilitates uniform conditioning when exposed to laser energy. In one embodiment, a polishing pad comprising a combination of a first material and a second material is provided, and the first material is more reactive to laser energy than the second material. In another embodiment, a method of texturing a composite polishing pad is provided. The method includes directing a laser energy source onto a surface of the polishing pad to affect a greater ablation rate within a first material having a greater laser absorption rate and a lesser ablation rate within a second material having a lesser laser absorption rate to provide a micro-textured surface consistent with microstructure of the composite polishing pad.

  • Patent number: 9403258
    Abstract: A method of forming a lapping plate. The method includes providing a lapping plate having a surface, spraying an adhesive onto the surface, spraying a slurry of abrasive particles and solvent onto the adhesive, and curing the adhesive to form an abrasive coating on the lapping plate. The adhesive may be, for example, epoxy, and the abrasive particles may be, for example, diamonds.

  • Patent number: 9278424
    Abstract: The present application relates to polishing pads for chemical mechanical planarization (CMP) of substrates, and methods of fabrication and use thereof. The pads described in this invention are customized to polishing specifications where specifications include (but not limited to) to the material being polished, chip design and architecture, chip density and pattern density, equipment platform and type of slurry used. These pads can be designed with a specialized polymeric nano-structure with a long or short range order which allows for molecular level tuning achieving superior themo-mechanical characteristics. More particularly, the pads can be designed and fabricated so that there is both uniform and nonuniform spatial distribution of chemical and physical properties within the pads.
