Latest Patents

Among his latest innovative patents are two notable contributions to the field of crystal growth. The first is titled "Vanadium compensated, SI SiC single crystals of NU and PI type and the crystal growth process thereof." This patent details a crystal growth apparatus and method wherein polycrystalline source material and a seed crystal are introduced into a growth environment. Under a specific sublimation growth pressure, a single crystal is sublimation-grown on the seed crystal through the precipitation of sublimated source material. A second gas flow containing dopant vapors facilitates this process, effectively removing impurities and ensuring high-quality crystal formation.

The second patent focuses on a "Large diameter, high-quality SiC single crystals, method and apparatus," which describes a seeded sublimation technique for creating large-diameter SiC single crystals. This method enhances the quality of the crystals by maintaining a shallow radial temperature gradient and utilizing a separation plate to filter the SiC bearing vapors. The resulting large-diameter SiC wafers exhibit low defect densities, which are crucial for various applications in semiconductor devices.
