Abstract
A contact is provided in a self-aligned manner to a doped region a semiconductor substrate by first forming a layer of a transition metal-boride compound over a selected region on the substrate. A layer of a transition metal-nitride compound is formed over the layer of transition metal-boride compound, and the structure is heated to drive dopant from the layer of transition metal-boride compound into the substrate. The transition metal-boride/transition metal nitride layers are patterned to leave a contact to the doped region.
