Abstract: The present invention provides systems and methods that facilitate formation and use of organic memory devices. An electroless plating process is employed that operates at relatively low temperatures and without employing electrical current. The electroless process is utilized to form conductive layers, such as electrodes and the like, from conductive materials. The process includes depositing an activation compound on selected areas and then applying a chemical solution. The chemical solution contains metal ions. Then, a chemical reaction occurs reducing the metal ions and thereby plating the metal ions and forming a conductive layer. Specifically, the electroless process can be employed to form a top electrode of an organic memory device.

Upon this layered structure further bulk deposition of conducting materials is done. Excess material is removed from the bulk layer and a sealing layer is formed on top to complete the interconnect structure.
