Abstract:
According to one disclosed embodiment, an electrical contact for use on a semiconductor device comprises an electrode stack including a plurality of metal layers and a capping layer formed over the plurality of metal layers. The capping layer comprises a refractory metal nitride. In one embodiment, a method for fabricating an electrical contact for use on a semiconductor device comprises forming an electrode stack including a plurality of metal layers over the semiconductor device, and depositing a refractory metal nitride capping layer of the electrode stack over the plurality of metal layers. The method may further comprise annealing the electrode stack at a temperature of less than approximately 875° C. In some embodiments, the method may additionally include forming one of a Schottky metal layer and a gate insulator layer between the electrode stack and the semiconductor device.
