Latest Patents
J A Sch Afer holds a patent for a "Method for forming pure group III-V compound semi-conductor films." This invention discloses a method of synthesizing a Group III-V compound semi-conducting film from a Group III metal alkyl and Group V hydride. The method involves providing a vacuum chamber for synthesis, adsorbing a monolayer of Group III metal alkyl on an inert surface, and backfilling the chamber with a Group V hydride. The process also includes providing atomic hydrogen atoms from electron-induced dissociation and retaining substantially all Group III metal on the surface. This results in a thermally stable Group III-V compound semi-conducting film on an inert SiO₂ surface. Additionally, methods for synthesizing multilayer Group III-V semi-conducting films, specifically GaN films, are disclosed, along with the necessary apparatus for synthesis.
