    Abstract: The treatment system provides a feature that may reduce cost of the electrochemical plating process by reusing the virgin makeup solution in the spent electrochemical plating bath. The treatment system provides a rotating filter shaft which receives the spent electrochemical plating bath and captures the additives and by-products created by the additives during the electrochemical plating process. To capture the additives and the by-products, the rotating filter shaft includes one or more types of membranes. Materials such as semi-permeable membrane are used to capture the used additives and by-products in the spent electrochemical plating bath. The treatment system may be equipped with an electrochemical sensor to monitor a level of additives in the filtered electrochemical plating bath.

    Abstract: A device includes an interconnect structure, a barrier multi-layer structure, an oxide layer, a pad metal layer, and a passivation layer. The barrier multi-layer structure is over the interconnect structure, the barrier multi-layer structure includes a first metal nitride layer and a second metal nitride layer over the first metal nitride layer. The oxide layer is over the barrier multi-layer structure, in which the oxide layer is an oxide of the second metal nitride layer of the barrier multi-layer structure. The pad metal layer is over the oxide layer. The passivation layer is in contact with the barrier multi-layer structure, the oxide layer, and the pad metal layer.
