Abstract
A local interconnect structure is formed in a semiconductor device. In one form, the semiconductor device has two conductive features (one of 54) and (56) which are to be electrically connected. A layer of metal (62), for instance titanium, is deposited on the device. The layer of metal is patterned to form a strap (64) which connects the two conductive features. After patterning the layer of metal to form the strap, the strap is thermally nitrided to form a conductive metal nitride local interconnect (66).
