摘要: A method of for electroless copper deposition using a Pd/Pd acetate seeding layer formed in using only two components (Pd acetate and solvent) to form an interconnect for a semiconductor device. The invention has two preferred embodiments. The first embodiment forms a Key seed layer composed of Pd/Pd acetate by a spin-on or dip process for the electroless plating of a Cu plug. The second embodiment forms a Pd passivation cap layer over the Cu plug to prevent the Cu plug from oxidizing.
