ABSTRACT:
Disclosed is a method of making semiconductor devices that comprises etching of a semiconductor layer, with a patterned metal layer acting as the etch mask. The patterned metal layer comprises a mask metal layer (exemplarily Ti) overlying a contact metal layer (exemplarily a Au-containing layer). In an exemplary embodiment the inventive method is used to manufacture InP-based heterojunction bipolar transistors.
