    摘要: A polishing system receives one or more target parameters for a selected peak in a spectrum of light, polishes a substrate, measures a current spectrum of light reflected from the substrate while the substrate is being polished, identifies the selected peak in the current spectrum, measures one or more current parameters of the selected peak in the current spectrum, compares the current parameters of the selected peak to the target parameters, and ceases to polish the substrate when the current parameters and the target parameters have a pre defined relationship.

    摘要: A polishing pad, polishing system, method of making a polishing pad and method of using a polishing pad. The polishing pad includes a polishing layer having a polishing surface, a backing layer with an aperture and a first portion that is permeable to liquid, and a sealant that penetrates a second portion of the backing layer adjacent to and surrounding the aperture such that the second portion is substantially impermeable to liquid. The aperture is positioned below a substantially fluid-impermeable element.

    摘要: A chemical mechanical polishing pad is described. A chemical mechanical polishing pad has an outer layer that includes a polishing surface, a first thinned region defined by a recess on a bottom surface of the pad, a first thick region surrounding the first thinned region, a second thinned region surrounding the first thick region, and a second thick region surrounding the second thinned region. The first thick region is not vertically extendable. The second thinned region defines one or more flexure mechanisms configured to make the first thinned region and the first thick region movable relative to the second thick region in a direction parallel or substantially parallel to the polishing surface.
