Latest Patents

Hishiki holds a patent for a compound semiconductor device, a compound semiconductor substrate, and a method for manufacturing a compound semiconductor device. This invention includes a compound semiconductor device that comprises a silicon substrate with a shape surrounding a hole when viewed in a plane. A silicon carbide (SiC) layer is formed on the top surface of the silicon substrate, covering the hole. Additionally, a nitride layer containing gallium is formed on the top surface side of the SiC layer. The device features source, drain, and gate electrodes formed on the top surface side of the nitride layer. The current flowing between the source and drain electrodes can be controlled by the voltage applied to the gate electrode. Notably, the silicon substrate does not exist in the area where the source, drain, and gate electrodes overlap when viewed from a direction orthogonal to the top surface of the silicon substrate.
