    摘要： A polishing pad has a polishing layer and a backing layer secured to the polishing layer. The polishing layer has a polishing surface, a first thickness, a first compressibility, and a hardness between about 40 to 80 Shore D. The backing layer has a second thickness and has a second compressibility greater than the first compressibility. The first thickness, first compressibility, second thickness and second compressibility are such that the polishing surface deflects more than the thickness non-uniformity of the polishing layer under an applied pressure of 1.5 psi or less.

    摘要： A method and apparatus for conditioning a conductive polishing material is described. In one embodiment, the pad dresser comprises a backing plate adapted to coupled to a conditioning head assembly, the backing plate comprising a rigid disk having a first side and an opposing second side, the second side having a perpendicular orientation to a centerline of the backing plate, and an annular member having a base portion adhered to the second side of the backing plate, wherein the annular member defines a conditioning surface opposite the second side that is radially sloped relative to a plane of the second side.
