Abstract
A method for fabricating a dynamic random access memory (DRAM) capacitor stack is disclosed wherein the stack includes a first electrode, a dielectric layer, and a second electrode. The first electrode is formed from a conductive binary metal. A dielectric layer is formed over the first electrode. The dielectric layer is subjected to a milliseconds anneal process that serves to crystallize the dielectric material and decrease the concentration of oxygen vacancies.
