Abstract

See full text

Techniques for device isolation for III-V semiconductor substrates are provided. In one aspect, a method of fabricating a III-V semiconductor device is provided. The method includes the steps of: providing a substrate having an indium phosphide (InP)-ready layer; forming an iron (Fe)-doped InP layer on the InP-ready layer; forming an epitaxial III-V semiconductor material layer on the Fe-doped InP layer; and patterning the epitaxial III-V semiconductor material layer to form one or more active areas of the device. A III-V semiconductor device is also provided.
