Abstract
A method of processing a workpiece to create a doped fin structure is disclosed. A portion of the workpiece is subjected to a pre-amorphizing implant to create an amorphized region. This amorphized region is then implanted with dopant species, at an implant energy and dose so that the dopant species are contained within the amorphized region. The doped amorphized region is then subjected to a laser melt anneal which crystallizes the amorphized region. The dopant profile is box-like, and the dopant is confined to the previously amorphized region.
