Abstract
Methods for forming ultrashallow junctions in semiconductor wafers include introducing into a shallow surface layer of a semiconductor wafer a dopant material that is selected to form charge carrier complexes which produce at least two charge carriers per complex, and short-time thermal processing of the doped surface layer to form the charge carrier complexes. The short-time thermal processing step may be implemented as flash rapid thermal processing of the doped surface layer, sub-melt laser processing of the doped surface layer, or RF or microwave annealing of the doped surface layer.
