  • Aluminum nitride body having graded metallurgy
    Patent number: 5763093
    Abstract: Disclosed is an aluminum nitride body having graded metallurgy and a method for making such a body. The aluminum nitride body has at least one via and includes a first layer in direct contact with the aluminum nitride body and a second layer in direct contact with, and that completely encapsulates, the first layer. The first layer includes 30 to 60 volume percent aluminum nitride and 40 to 70 volume percent tungsten and/or molybdenum while the second layer includes 90 to 100 volume percent of tungsten and/or molybdenum and 0 to 10 volume percent of aluminum nitride.
    Type: Grant
    Filed: June 3, 1996
    Date of Patent: June 9, 1998
    Assignees: International Business Machines Corporation, The Carborundum Company

  • High thermal conductivity substrate and the method of brazing a cap thereto
    Patent number: 5742021
    Abstract: Temperature gradients between a ceramic substrate of high thermal conductivity and the braze materials used to attach a metallic device such as a cap are reduced by using an embedded internal heat source in the substrate to minimize the thermal gradient, thereby minimizing the stresses that can result in substrate cracking when a cap is brazed onto the substrate.

  • Laser ablation apparatus and method
    Patent number: 5491319
    Abstract: A laser ablation apparatus and method removes undesired portions of a workpiece. An industrial laser generates a beam of optical energy and directs the beam at the workpiece. A mechanism in the path of the beam for shapes the cross-section of the beam and includes first and second linear actuators on opposite sides of the beam path. Each of the actuators includes a plurality of linear members, with each linear member being adjacent to and in contact with another linear member, and means for individually inserting and retracting each of said members into and out of said beam path a desired distance to thereby shape the beam so as to ablate only undesired portions of the workpiece.
