Title: Innovations by Paul M DeLuca
Introduction
Paul M DeLuca is a notable inventor based in Providence, RI (US). He has made significant contributions to the field of semiconductor materials, holding a total of 6 patents. His work primarily focuses on enhancing the performance of bipolar transistors through innovative materials and techniques.
Latest Patents
One of his latest patents involves a bipolar transistor that utilizes a semiconductor material with a high carbon dopant concentration. This material includes gallium, indium, arsenic, and nitrogen, resulting in low sheet resistivity due to the high carbon dopant concentrations achieved. The invention allows for the base layer of gallium arsenide-based heterojunction bipolar transistors to be lattice-matched to gallium arsenide emitter and/or collector layers by controlling the concentrations of indium and nitrogen in the base layer. Additionally, the base layer can feature a graded band gap formed by adjusting the flow rates during the deposition of III and V additive elements. This innovation ensures a consistent doping-mobility product value during deposition, enabling the regulation of pre-selected base-emitter voltages at junctions within the resulting transistor.
Another significant patent by DeLuca is for a bipolar transistor with a lattice-matched base layer. This semiconductor material, which also has a high carbon dopant concentration, is composed of gallium, indium, arsenic, and nitrogen. It is particularly useful in forming the base layer of gallium arsenide-based heterojunction bipolar transistors, as it can be lattice matched to gallium arsenide by controlling the concentration of indium and nitrogen. The low sheet resistivity achieved through high carbon dopant concentration is a key feature of this invention.
