Abstract
A device that includes a semiconductor device and a contact electrode with a first side that is opposite a second side. The first side abuts the semiconductor device. The contact electrode has a stoichiometry that varies from the first side to the second side. The stoichiometry of the first side inhibits the diffusion of metal from the semiconductor device into the first contact electrode.
