Title: Innovations of Hubert P. Davis
Introduction
Hubert P. Davis is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of semiconductor technology, holding a total of 6 patents. His work focuses on enhancing the efficiency and functionality of silicon devices.
Latest Patents
One of his latest patents is titled "Method and apparatus for self-doping contacts to a semiconductor." This invention provides a system and method for creating self-doping contacts to silicon devices. The contact metal is coated with a layer of dopant and subjected to high temperature, allowing for the alloying of silver with silicon. This process simultaneously dopes the silicon substrate and forms a low-resistance ohmic contact. A self-doping negative contact can be formed from unalloyed silver, which may be applied to the silicon substrate through various methods such as sputtering, screen printing, or evaporation. The silver is coated with a layer of dopant, and once applied, the silver, substrate, and dopant are heated above the Ag-Si eutectic temperature. As the temperature decreases, the molten silicon reforms through liquid-phase epitaxy, incorporating dopant atoms into the re-grown silicon lattice. The final contact material is an alloy of silver and silicon, ensuring good electrical conductivity.
