ABSTRACT:
A method of manufacturing a compound semiconductor device has the steps of mirror-polishing a surface of each of two compound semiconductor substrates, bringing the mirror-polished surfaces of the two compound semiconductor substrates in contact with each other in a clean atmosphere and in a state wherein substantially no foreign substances are present therebetween, and annealing the compound semiconductor substrates which are in contact with each other so as to provide a bonded structure having a junction with excellent electrical characteristics at the interface.
