Abstract

A method of fabricating an epitaxial compound semiconductor III-V wafer suitable for the subsequent fabrication of at least two different types of integrated active devices (such as an HBT and a FET) on such wafer by providing a substrate; growing a first epitaxial structure on the substrate; and growing a second epitaxial structure on the first epitaxial structure.
