Latest Patents

Izumi's latest patents include groundbreaking work in two key areas. The first patent focuses on the growth of GaN layers on quartz substrates. This method involves depositing a GaN film on a quartz substrate with a z-cut plane of (0001) on its surface. After the deposition, the quartz substrate is removed, leaving the GaN film as a substrate for forming GaN-based compound semiconductor layers. The second patent pertains to an X-ray microbeam generating method and device. This invention allows for the generation of an X-ray microbeam with a restricted divergence angle and desirable planeness in regions outside the focus. It compensates for changes in asymmetry due to variations in X-ray wavelengths, maintaining a constant degree of asymmetry. Additionally, the condensing conditions, including X-ray energy and beam size, can be independently set.
