Abstract
A dual damascene method of fabricating an interconnection level of conductive lines and connecting vias etches a via opening in a first insulating layer. A photoresist layer that the defines the conductive wiring is deposited and patterned on the first insulating layer after the via opening has been created. The via opening and the conductive wire opening in the resist layer are then filled with the conductive material, such as copper. The resist layer may then be removed and a second insulating layer provided over the first insulating layer.
