Abstract
A method for manufacturing a semiconductor device with a Schottky electrode includes the steps of subjecting the surface of a GaAs substrate to a sputtering etching process in a sputtering processing chamber of a sputtering device; and depositing Schottky electrode material by sputtering on the surface of the substrate to form a Schottky electrode in the processing chamber without exposing the substrate to the atmosphere.
