  • Publication number: 20100221985
    Abstract: An aspect of the present disclosure relates to a chemical mechanical planarization pad including a first domain and a second continuous domain wherein the first domain includes discrete elements regularly spaced within the second continuous domain. The pad may be formed by forming a plurality of openings for a first domain within a second continuous domain of the pad, wherein the openings are regularly spaced within the second domain, and forming the first domain within the plurality of openings in second continuous domain. In addition, the pad may be used in polishing a substrate with a polishing slurry.

  • Publication number: 20090258588
    Abstract: A polishing pad and a method of producing a polishing pad. The method includes providing a mold, having a first cavity and a second cavity, wherein the first cavity defines a recess, providing a polymer matrix material including void forming elements in the recess, forming a polishing pad and removing at least a portion of the elements from the polishing pad forming void spaces within the polishing pad by one of a chemical method or mechanical method, prior to use in chemical/mechanical planarization procedures.

  • Publication number: 20090246504
    Abstract: A chemical-mechanical planarization polishing pad is provided comprising a network of elements dispersed within a polymer, a plurality of voids formed in the pad and at least a portion of said network of elements is connected to at least a portion of the voids. A method of forming the pad is also disclosed, which comprises providing a composition, the composition comprising a network of elements and at least one of a polymer or a reactive prepolymer, introducing a gas to the composition and using the gas to produce a plurality of voids in the composition. A method of forming voids is also disclosed, which relies upon the application of a force to the network of elements within the polymer or reactive polymer, followed by removal of the force and void formation.

  • Publication number: 20090170413
    Abstract: The present disclosure relates to a polishing pad. The polishing pad may include a polymer layer having a three-dimensional network therein and a composite layer having the ability to equalize pressure across the pad surface, including a first adhesive wherein the composite exhibits a hydrostatic modulus of 1 to 500 psi when compressed at a pressure of 1 to 50 psi.

  • Publication number: 20090170410
    Abstract: The present disclosure relates to a polishing pad including a chemical agent present in an amount sufficient to be released and dissolving into an aqueous abrasive particle polishing medium during chemical mechanical planarization and reducing abrasive particle agglomeration and a binder. The pad includes a surface such that as the pad is abraded the surface is renewed exposing at least a portion of the chemical agent.

  • Publication number: 20090142989
    Abstract: A chemical mechanical polishing pad. The pad includes a surface and a polymer matrix capable of transmitting at least a portion of incident radiation. In addition, at least one embedded structure in the polymer matrix, including a portion of the pad where the embedded structure is not present, and a window integral to the pad defined by the portion of the pad where the embedded structure is not present.
