ABSTRACT:
In situ removal of selected or patterned portions of semiconductor layers is accomplished by induced evaporation enhancement to form patterned buried impurity layers in semiconductor devices, such as heterostructure lasers and array lasers, which function as buried impurity induced layer disordering (BIILD) sources upon subsequent annealing. These layers may be formed to either function as buried impurity induced layer disordering (BIILD) sources or function as a reverse bias junction configuration of confining current to the active region of a laser structure. Their discussion here is limited to the first mentioned function.
