Title: David Neil Casey: Innovator in Semiconductor Technology
Introduction
David Neil Casey is a notable inventor based in Lancashire, GB. He has made significant contributions to the field of semiconductor technology, holding a total of three patents. His work focuses on improving the performance and reliability of semiconductor devices.
Latest Patents
One of his latest patents is for a bipolar transistor with a low saturation voltage. This invention features a bipolar transistor with a specific area resistance of less than about 500 mOhms·mm. It comprises a first semiconductor region of a first conductivity type that defines a collector region, a second semiconductor region of a second conductivity type that defines a base region, and a third semiconductor region of the first conductivity type that defines an emitter region. Additionally, a metal layer provides contacts to the base and emitter regions, with a thickness greater than about 3 μm.
Another significant patent is a semiconductor contact fabrication method. This method aims to reduce damage to a semiconductor structure caused by the migration of constituents from a first component part into a subsequently deposited second component part. A third component part is deposited before the second component part, positioned to be contacted by the second component part adjacent to the surface of the first component part. The third component part acts as a donor of constituents to the second component part, which helps mitigate the migration of constituents from the first component part.
