Latest Patents

Mitsuaki Seiwa holds a patent for an "Epitaxial process for III-V compound semiconductor." This vapor-phase epitaxial process enables the easy growth of a III-V compound semiconductor layer, including a .delta.-doped layer. The process requires essentially no change or rearrangement of the conventional vapor-phase epitaxial reactor system, only a simple change in the method of controlling the system. The epitaxial process includes feeding an epitaxial growth gas into a reactor vessel containing a III group element as a raw material and an epitaxial substrate made of a semiconductor. This allows for the epitaxial growth of a layer made of a III-V compound semiconductor on the substrate using the chloride CVD process. The process also involves displacing the gas in the reactor vessel with an inert gas and feeding an epitaxial growth gas consisting of a chloride of a V group element and a carrier gas to grow a buffer layer on the substrate.
