Patent number: 6890021Abstract: A modular segmented structural reinforcement system for use with closed forms or cavities defined with automotive vehicles having a plurality of modular segments designed to be secured within a defined portion of an automotive vehicle applications. An expandable or bonding material, such as an epoxy-based reinforcing foam or other sound absorption, damping, vibration reduction, or sealing material is disposed on at least a portion of the outer surface of each of the plurality of segments. Once the system is flexible fitted within the closed form or placed within a selected cavity of an automotive vehicle, the material expands and cures during an automobile assembly operation, bonding the reinforcement system to the segments.

Patent number: 6716712Abstract: During the production of integrated semiconductor structures, it is often necessary to differently dope immediately adjacent regions. A method is provided for producing two adjacent regions of a predetermined area in an integrated semiconductor, whereby a first region of the two adjacent regions includes a doping with a lower target concentration than a second region. The predetermined area of a semiconductor blank is doped with a dopant until a concentration of the dopant is obtained that is at least as high as the target concentration of the second region. A protective layer is applied to the second region, and the dopant is out-diffused from the first region until a concentration of dopant is obtained that corresponds to the target concentration of the first region.Type: GrantFiled: January 22, 2002Date of Patent: April 6, 2004Assignee: Infineon Technologies AGInventor: Josef Böck

Patent number: 6635545Abstract: The bipolar transistor is produced such that a connection region of its base is provided with a silicide layer, so that a base resistance of the bipolar transistor is small. No silicide layer is produced between an emitter and an emitter contact and between a connection region of a collector and a collector contact. The base is produced by in situ-doped epitaxy in a region in which a first insulating layer is removed by isotropic etching such that the connection region of the base which is arranged on the first insulating layer is undercut. In order to avoid defects of a substrate in which the bipolar transistor is partly produced, isotropic etching is used for the patterning of auxiliary layers, whereby etching is selective with respect to auxiliary layers lying above, which are patterned by anisotropic etching.Type: GrantFiled: June 3, 2002Date of Patent: October 21, 2003Assignee: Infineon Technologies AGInventors: Josef Böck, Wolfgang Klein, Herbert Schäfer, Martin Franosch, Thomas Meister, Reinhard Stengl
