Latest Patents

Richard Liu holds a patent titled "Maximizing cubic phase group III-nitride on patterned silicon." This invention involves a device that includes a non-polarization material composed of several layers. The first layer is silicon (100), which defines a U-shaped groove with a bottom portion (100) and silicon sidewalls (111) at an angle to the bottom. The second layer consists of a patterned dielectric on top of the silicon (100), defining vertical sidewalls of the U-shaped groove. A third layer of a buffer covers both the first and second layers. Finally, a fourth layer of gallium nitride is deposited on the buffer within the U-shaped groove. This fourth layer includes cubic gallium nitride (c-GaN) formed at merged growth fronts of hexagonal gallium nitride (h-GaN) extending from the silicon sidewalls (111). The deposition thickness (h) of the gallium nitride above the first layer of silicon (100) is such that the c-GaN completely covers the h-GaN between the vertical sidewalls. Richard Liu has 1 patent to his name.
