Title: Kulwant S Egan: Innovator in Semiconductor Technology
Introduction
Kulwant S Egan is a prominent inventor based in San Jose, California. He has made significant contributions to the field of semiconductor technology, holding a total of four patents. His work focuses on improving the efficiency and functionality of bipolar transistors, which are essential components in various electronic devices.
Latest Patents
One of Kulwant S Egan's latest patents involves an improved method and apparatus for forming a self-aligned epitaxial base bipolar transistor in semiconductor materials. This innovative method includes the formation of an intrinsic base region by growing an epitaxial semiconductor material over a collector region. A raised sacrificial emitter core is then created on the intrinsic base region, followed by the deposition of a conformal spacer layer over the core. The spacer material is anisotropically etched to form a protective spacer ring around the sacrificial emitter core. An extrinsic base is formed by implanting dopants into the epitaxial base region, preserving the emitter region with the sacrificial emitter core and spacer ring. The spacer ring also self-aligns the extrinsic base region to the emitter region. Finally, the protective components are removed, and the self-aligned epitaxial base bipolar transistor is formed by doping the emitter region.
