Abstract
A method and apparatus is provided for forming a resistive memory device having good adhesion among the components thereof. A first conductive layer is formed on a substrate, and the surface of the first conductive layer is treated to add adhesion promoting materials to the surface. The adhesion promoting materials may form a layer on the surface, or they may incorporate into the surface or merely passivate the surface of the first conductive layer. A variable resistance layer is formed on the treated surface, and a second conductive layer is formed on the variable resistance layer. Adhesion promoting materials may also be included at the interface between the variable resistance layer and the second conductive layer.
