摘要:
A passivated metal structure and a method of forming the metal structure is disclosed. According to one embodiment, the patterned metal structure, such as conductive lines, are formed on a substrate. The copper lines are passivated by a polymer liner between the copper lines and a low k dielectric filling the spaces between the conductive lines. The polymer liner is preferably deposited on the sidewalls of the conductive lines by electro-grafting. The polymer liner may also be used in a damascene process according to a second embodiment.
