Latest Patents

Raju Ahmed holds a patent for a method of incorporating semiconductors on a polycrystalline diamond substrate. This patent outlines a process where a buffer layer, such as GaN, is grown on a transition layer like AlN/AlGaN residing on a substrate. A silicon nitride layer is then grown on the buffer layer. After selectively seeding diamond on the silicon nitride layer, the selective seeding of the diamond is dry etched to create regions with seeded diamond and regions without seeded diamond. The silicon nitride is selectively etched in the regions without seeded diamond, allowing diamond to grow in the seeded regions. Additional Group III-nitride semiconductor material, such as GaN, is then grown in the etched regions to fill them, achieving a level with the regions containing diamond. An epitaxial overgrowth of the Group III semiconductor material is subsequently performed at and above the level of the regions with diamond.
