Abstract

Methods of forming cobalt films utilizing a cobalt precursor comprising an additive are described. Those methods may include adding an additive to a cobalt precursor, wherein the cobalt precursor is located in an ampoule that is coupled with a deposition tool, and then forming a cobalt film using the cobalt precursor comprising the additive. Non-volatile decomposition products of the cobalt precursor are solubilized in the ampoule.
