Title: The Innovative Contributions of H McDonald Hobgood
Introduction
H McDonald Hobgood, an esteemed inventor based in Pittsboro, NC, has made significant contributions to the field of semiconductor technology. With a total of two patents to his name, Hobgood's innovative work is focused on advancing the methods of growing high-purity silicon crystals, which are essential for various electronic applications.
Latest Patents
Hobgood's most recent patents include a groundbreaking method and apparatus for growing high purity single crystal silicon and another for growing semiconductor-grade silicon carbide boules. The first patent describes a process where pure silicon feedstock is melted and vaporized. The vaporized silicon then reacts with a high purity carbon-containing gas, such as propane, resulting in gaseous species that are deposited on a silicon carbide seed crystal. This process leads to the growth of monocrystalline silicon carbide, a material known for its superior electronic properties.
The second patent outlines a method for growing 4H polytype silicon carbide crystals using a physical vapor transport system. This method cleverly maintains the surface temperature of the crystal at less than about 2160 degrees Celsius and adjusts the pressure within the system to compensate for the lower growth temperature, enabling the efficient production of high-quality silicon carbide crystals.
