Abstract:
1. A method for forming a conductor structure, comprising: providing a substrate; forming a patterned dielectric layer on the substrate in which the dielectric layer has a first opening exposing a portion of the substrate, and the first opening has one end with a first width being proximal to the substrate, and the other end with a second width being distal from the substrate; forming a patterned organic material layer on the patterned dielectric layer, in which the patterned organic material layer has a second opening corresponding to a portion of the first opening and the second opening exposes the substrate through the first opening, and the second opening has a third width substantially smaller than at least one of the first width and the second width; forming a first barrier layer on a portion of the exposed portion of the substrate and on the patterned organic material layer; forming a metal layer on the first barrier layer; and removing the patterned organic material layer, as well as the first barrier layer and the metal layer thereon.
