Abstract
A multilayer electrode structure has a conductive layer including aluminum, an oxide layer formed on the conductive layer, and an oxygen diffusion barrier layer. The oxide layer includes zirconium oxide and/or titanium oxide. The oxygen diffusion barrier layer is formed at an interface between the conductive layer and the oxide layer by re-oxidizing the oxide layer. The oxygen diffusion barrier layer includes aluminum oxide.
