Latest Patents
Toshihisa Katamine holds a patent for a "Method and system for manufacturing III-V Group compound semiconductor and III-V Group compound semiconductor." This patent describes a semiconductor manufacturing system utilizing Metal-Organic Chemical Vapor Deposition (MOCVD). The system features a lead-in member that guides feed gas onto the surface of a semiconductor substrate within a reactor. The lead-in member is designed as a hollow structure that forms a feed gas guide passage, equipped with multiple orifices. This design allows the feed gas to be jetted in a direction perpendicular to the prescribed flow, ensuring that the semiconductor substrate is uniformly bathed in the gas flow. The pressure differential created between the inner and outer sides of the nozzle member facilitates a consistent flow rate across the substrate's surface. This innovative method enables the individual leading of multiple feed gases to the substrate, promoting the formation of desired thin film crystals.
