Latest Patents:

Among his latest innovations is a patent for a **wafer base for silicon carbide semiconductor devices**. This invention discloses a semiconductor wafer base suitable for device fabrication in silicon carbide. It features a single crystal substrate that is a transition metal carbide alloy with a cubic crystal structure, coupled with an unpolytyped, single crystal 3C-silicon carbide overlay that is epitaxially related to the substrate. The substrate is preferably an alloy composed of titanium carbide, tantalum carbide, vanadium carbide, and niobium carbide, with a lattice parameter difference from 3C-silicon carbide of less than 1%. This groundbreaking design allows for the production of large, single crystal substrates that are free from cracks, dislocations, or other defects. The 3C-silicon carbide epitaxial overlay can be deposited using techniques such as chemical vapor deposition and reactive evaporation, and it may be doped with n- or p-type dopants. These advancements render the 3C-silicon carbide particularly valuable for constructing semiconductor devices that operate under high temperatures, high powers, and in corrosive environments.
