Abstract: Electrical connections to specified semiconductor or electrically conductive portions (18, 26, and 30) of a structure created from a semiconductive body (10) are created by a process in which a titanium contact layer (34) is deposited on the structure over the specified portions. An electrically conductive barrier material layer (36) which consists principally of non-titanium refractory material is formed over the contact layer. The resulting structure is then annealed at a temperature above 550.degree. C. in order to lower the contact resistance. The anneal is preferably done at 600.degree. C. or more for 10-120 seconds in a gas whose principal constituent is nitrogen. An electrically conductive primary interconnect layer is formed over the barrier material layer after which all three layers are patterned to create a composite interconnect layer.
