    摘要： Grooves are formed in a COD pad by positioning the pad on a supporting surface with a working surface of the pad in spaced relation opposite to a router bit and at least one projecting stop member adjacent to the router bit, an outer end portion of the bit projecting beyond the stop. When the bit is rotated, relative axial movement between the bit and the pad causes the outer end portion of the bit to cut an initial recess in the pad. Relative lateral movement between the rotating bit and the pad then forms a groove which extends laterally away from the recess and has a depth substantially the same as that of the recess. The depths of the initial recess and the groove are limited by applying a vacuum to the working surface of the pad to keep it in contact with the stop member(s). Different lateral movements between the bit and the pad are used to form a variety of groove patterns, the depths of which are precisely controlled by the stop member(s).

    摘要： A method of making a polishing pad having a body comprising fibers embedded in a matrix polymer formed by a reaction of polymer precursors. The fibers define interstices, and the precursors fill these interstices substantially completely before completion of the reaction. The method comprising placing the fibers and the precursors in a cavity of a mold for shaping the polishing pad; applying a differential pressure across a mold cavity, where the differential pressure and the amount of precursors are sufficient to cause the precursors to fill the interstices substantially completely before completion of the reaction; and applying sufficient heat to the mold to at least partially cure the polishing pad by causing the precursors to react.

    摘要： A computer program product, comprising a computer readable storage device having a computer readable program code stored therein, said program code including an algorithm adapted to be executed by a computer to implement a method. First, design information of a design structure is provided including a back-end-of-line layer of an integrated circuit which includes N interconnect layers, wherein N is a positive integer. Next, each interconnect layer is divided into multiple pixels. Next, a first path of a traveling particle in a first interconnect layer of the N interconnect layers is determined. Next, M path pixels of the multiple pixels of the first interconnect layer on the first path of the traveling particle are identified, wherein M is a positive integer. Next, a first loss energy lost by the traveling particle due to its completely passing through a first pixel of the M path pixels is determined.
