Publication number: 20070026574Abstract: Disclosed are interconnect structures and methods which utilize a bonding surface comprising copper nitride. The interconnect structures include a bonding surface comprising copper nitride which is effective at preventing oxidation and/or other unwanted corrosion of the underlying conductive material while providing the basis for a high conductivity bond. The copper nitride bonding surface provides a relatively non-conductive, corrosion-resistant bonding surface while at the same time being readily transformed into a conductive layer at or just prior to the time of bonding.Type: ApplicationFiled: April 8, 2004Publication date: February 1, 2007Applicant: KULICKE & SOFFA INVESTMENTS INC.Inventors: David Beatson, Horst Clauderg, Kenneth Dury

Patent number: 6960022Abstract: A “hybrid” or macrocomposite guideway, wherein the “traditional” or existing guideway material (e.g., hardened steel) is maintained as the wear resistant, low friction surface intended to be in physical contact with one or more bearings, and further wherein this surface is backed up or supported by a substrate comprising a stiff, lightweight material. This macrocomposite guideway combines the desirable friction and wear characteristics of the traditional bearing materials with the stiffness and low mass of advanced materials. Candidate substrate materials include composites having a ceramic and/or a metallic matrix, monolithic ceramics or monolithic light metals. A cladding comprising the hardened steel wear surface layer may be attached to the rigid, lightweight substrate by adhesive bonding, mechanical fasteners or other mechanical fit such as a friction or interference fit. Preferably, though, the attachment is by means of a metallurgical bond.Type: GrantFiled: July 10, 2003Date of Patent: November 1, 2005Assignee: Kulicke & Soffa Investments, Inc.Inventors: David T.

Patent number: RE39018Abstract: Two imaging equipment are provided at a pair of cutting blade units, and the two imaging equipment image patterns at first positions in proximity to the center of a wafer at the same time. A controller drives drive mechanisms to align the wafer in such a way that current image patterns at the first positions can match with a reference pattern at the first positions. Then, the two imaging equipment are moved to positions for imaging patterns at second positions at the outer circumference of the wafer to image the patterns at the second positions. The controller drives the drive mecha- nisms to align the wafer in such a way that current image patterns at the second positions can match with a reference pattern at the second positions.Type: GrantFiled: January 23, 2002Date of Patent: March 21, 2006Assignees: Tokyo Seimitsu Co., Ltd., Kulicke & Soffa Investments, Inc.Inventors: Masayuki Azuma, Hirofumi Shimoda, Mani Fischer
