Abstract
A method for reducing the leakage current in DRAM Metal-Insulator-Metal capacitors includes forming a flash layer between the dielectric layer and the first electrode layer. A method for reducing the leakage current in DRAM Metal-Insulator-Metal capacitors includes forming a capping layer between the dielectric layer and the second electrode layer. The flash layer and the capping layer can be formed using an atomic layer deposition (ALD) technique. The precursor materials used for forming the flash layer and the capping layer are selected such they include at least one metal-oxygen bond. Additionally, the precursor materials are selected to also include 'bulky' ligands.
