    摘要: Embodiments of the invention described herein generally provide methods and apparatuses for forming cobalt silicide layers, metallic cobalt layers, and other cobalt-containing materials. In one embodiment, a method for forming a cobalt silicide containing material on a substrate is provided which includes exposing a substrate to at least one preclean process to expose a silicon-containing surface, depositing a cobalt silicide material on the silicon-containing surface, depositing a metallic cobalt material on the cobalt silicide material, and depositing a metallic contact material on the substrate. In another embodiment, a method includes exposing a substrate to at least one preclean process to expose a silicon-containing surface, depositing a cobalt silicide material on the silicon-containing surface, expose the substrate to an annealing process, depositing a barrier material on the cobalt silicide material, and depositing a metallic contact material on the barrier material.
