Abstract: A semiconductor processing tool includes a cleaning chamber configured to perform a post-chemical mechanical polishing/planarization (post-CMP) cleaning operation in an oxygen-free (or in a near oxygen-free) manner. An inert gas may be provided into the cleaning chamber to remove oxygen from the cleaning chamber such that the post-CMP cleaning operation may be performed in an oxygen-free (or in a near oxygen-free) environment. In this way, the post-CMP cleaning operation may be performed in an environment that may reduce oxygen-causing corrosion of metallization layers and/or metallization structures on and/or in the semiconductor wafer, which may increase semiconductor processing yield, may decrease semiconductor processing defects, and/or may increase semiconductor processing quality, among other examples.
