Abstract
A method of manufacturing a semiconductor structure, and the resultant structure. The method includes forming an oxide layer above a substrate. The method includes forming a metal layer above the oxide layer. The method includes forming a first capping layer above the metal layer. A material forming the first capping layer may be titanium oxide, or titanium oxynitride. The method includes annealing the semiconductor structure. Annealing the semiconductor structure may result in diffusing a metal from the metal layer into the oxide layer.
