    摘要: A method of manufacturing a chemical-mechanical polishing (CMP) pad comprises the steps of (a) forming a layer of a polymer resin liquid solution (i.e., a polymer resin dissolved in a solvent); (b) inducing a phase separation in the layer of polymer solution to produce an interpenetrating polymeric network comprising a continuous polymer-rich phase interspersed with a continuous polymer-depleted phase in which the polymer-depleted phase constitutes about 20 to about 90 percent of the combined volume of the phases; (c) solidifying the continuous polymer-rich phase to form a porous polymer sheet; (d) removing at least a portion of the polymer-depleted phase from the porous polymer sheet; and (e) forming a CMP pad therefrom. The method provides for microporous CMP pads having a porosity and pore size that can be readily controlled by selecting the concentration polymer resin in the polymer solution, selecting the solvent based on the solubility parameters of the polymer in the solvent polarity of solvent, selecting the conditions for phase separation, and the like.

    摘要: The invention provides a method of chemically-mechanically polishing a substrate. A substrate comprising ruthenium and copper is contacted with a chemical-mechanical polishing system comprising a polishing component, hydrogen peroxide, an organic acid, at least one heterocyclic compound comprising at least one nitrogen atom, and water. The polishing component is moved relative to the substrate, and at least a portion of the substrate is abraded to polish the substrate. The pH of the polishing system is about 6 to about 12, the ruthenium and copper are in electrical contact, and the difference between the open circuit potential of copper and the open circuit potential of ruthenium in the polishing system is about 50 mV or less.
