Copper has lower resistivity and higher electromigration immunity compared to Al. However, unlike Al, copper can not be easily plasma etched, and one must resort to a damascene process and use CMP (Chemical Mechanical Polishing) to remove the excess copper and barrier materials, thereby accu-rately defining the copper lines in the trenches.

Sep 26, 2019· The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
