Abstract :
The realization of a semi-insulating buried layer in a InP-based epitaxial structure is discussed by the selective ion implantation of Fe. Results indicate the feasibility of the production of a buried semi-insulating, current-blocking region with the selective implant of Fe into InP followed by an epitaxial overgrowth. The study of the involved physical processes revealed many interesting aspects. A strong difference is evidenced between the annealing behavior of samples implanted above or below the amorphization threshold. Particular attention has been devoted to the study of the solid phase epitaxial growth of the amorphous layer and of the Fe redistribution and segregation mechanisms
