Patent number: 6830780Abstract: A multilayer brazeable metallization structure for diamond components and method for producing it are described. The brazeable metallization finds particular application for the attachment of diamond components such as heat spreaders in electronic packages that incorporate high power semiconductor devices. In the present invention, a diamond component is provided with a multilayer coating of metals including depositing a first layer of chromium for adhesion onto at least a portion of the diamond component, depositing a second barrier layer of a refractory metal for a barrier onto at least portion of the chromium layer, and a top layer of copper, silver or gold for wetting. This top layer is thick (greater than 5 microns), without sacrificing resistance to delamination, particularly at brazing conditions. It is obtained by depositing a layer of a first metal onto at least a portion of the refractory metal layer, and depositing a layer of a second metal onto at least a portion of the first metal layer.Type: GrantFiled: September 27, 2001Date of Patent: December 14, 2004Assignee: Morgan Chemical Products, Inc.Inventor: Ronald Petkie

Patent number: 6723420Abstract: This invention relates to the nature of thick film compositions that are specifically designed for the fabrication of circuit elements on diamond substrates, especially resistive elements. The nature of diamond sheet material requires special consideration because of its relatively low coefficient of thermal expansion and its sensitivity to oxygen at elevated processing temperatures. The general compositional requirements of thick film paste formulations are provided as a basis for accommodating the particular physical properties of diamond, and thereby establishing a method by which high performance microelectronic components can be fabricated economically. Thick film pastes containing certain borosilicate glasses, metal components, and optionally semiconducting materials are demonstrated to possess favorable behavior in terms of mechanical and electrical properties after sintering. Resistive elements on diamond can be fabricated by adding conductive components to a borosilicate glass.Type: GrantFiled: April 9, 2002Date of Patent: April 20, 2004Assignee: Morgan Chemical Products, Inc.Inventor: Ronald R.

Patent number: 6685656Abstract: A portable therapeutic device and method of use generate longitudinally propagating ultrasound and shear waves generated by such longitudinally propagating ultrasound to provide effective healing of wounds. A transducer having an operative surface is disposed substantially adjacent to the wound to emit ultrasound to propagate in the direction of the wound to promote healing. Reflections of the ultrasound by bone tissue, by skin layers, or by internally disposed reflective media propagate toward the wound as longitudinal waves, with shear waves generated by the longitudinal waves for the healing of the wound. A focusing element is used for focusing the propagation of the ultrasound at a predetermined angle toward the wound. The operative surface of the transducer may be annularly shaped to encircle the wound to convey the ultrasound and/or reflected ultrasound thereto.Type: GrantFiled: January 13, 1999Date of Patent: February 3, 2004Assignee: Exogen, Inc.Inventors: Luiz R.
