Abstract:
An opening is formed within a dielectric material overlying a semiconductor substrate. The opening may comprise a via portion and a trench portion. During the manufacturing process a treatment chemical is placed into contact with the exposed surfaces in order to release charges that have built up on the surfaces. By releasing the charges, a surface change potential difference is reduced, helping to prevent galvanic corrosion from occurring during further manufacturing.

Claim (Index 8):
A method of manufacturing a semiconductor device, the method comprising:\n forming a first via opening within a low-k dielectric layer; forming a first trench opening within the low-k dielectric layer, wherein the forming the first trench opening extends the first via opening through the low-k dielectric layer; and applying a treatment chemical within the first via opening and the first trench opening, wherein the treatment chemical releases surface charges from within the first via opening and the first trench opening.
