  • Patent number: 7429367
    Abstract: Provided are methods for manufacturing improved cerium oxide abrasives suitable for forming slurry compositions suitable for CMP processes. The cerium oxide abrasives are produced by the heat treatment of a mixture of a cerium precursor compound under conditions that produce primary cerium oxide particles that are incorporated in larger secondary abrasive particles. The structure of the primary cerium oxide particles and/or the presence of incompletely oxidized cerium within the secondary abrasive particle tend to reduce its mechanical strength, thereby reducing the likelihood of damaging a substrate surface during a CMP process utilizing such abrasives.

  • Publication number: 20070037486
    Abstract: A polishing pad of a CMP apparatus has a plurality of pores. A characteristic associated with the pores, such as average size or pore density, varies substantially from region to region of the pad across the pad in a diametral direction of the pad. The polishing pad can be designed and manufactured using sample pads whose pore characteristics differ from each other. CMP test processes are performed in which the sample pads are used to polish test wafers, and the rates at which the test wafers are polished are measured and stored in a database. The polishing pad is fabricated using data from the database so that a chemical mechanical polishing apparatus employing the pad will polish wafers with a high degree of uniformity. The database can be used to select sample pads from a stockpile. Sections of the sample pads are cut out, respectively, and fastened to one another.
