Publication number: 20020074311Abstract: A method for monitoring the endpoint for a silicon wafer or other semiconductor device CMP process. A fixed abrasive article, such as a three dimensional abrasive article, is used to planarize the wafer in the presence of a working fluid. A component in the effluent from the CMP process is monitored to predict the CMP endpoint. In some embodiments, the component monitored is a reaction production between a component from the silicon wafer and a reactant.Type: ApplicationFiled: December 1, 2000Publication date: June 20, 2002Inventor: Eric F. Funkenbusch

Patent number: 4971933Abstract: A ternary ceramic alloy which produces toughening of zirconia and zirconia composites through the stress transformation from tetragonal phase to monoclinic phase. This alloy, having the general formula Ce.sub.x Hf.sub.y Zn.sub.1-x-y O.sub.2, is produced through the addition of appropriate amounts of ceria and hafnia to the zirconia. Typically, improved toughness is achieved with about 5 to about 15 mol % ceria and up to about 40 mol % hafnia. The preparation of alloys of these compositions are given together with data as to the densities, tetragonal phase content, hardness and fracture toughness. The alloys are useful in preparing zirconia bodies as well as reinforcing ceramic composites.Type: GrantFiled: March 14, 1989Date of Patent: November 20, 1990Assignee: Martin Marietta Energy Systems, Inc.Inventors: Paul F. Becher, Eric F. Funkenbusch
