Abstract:
An interconnect structure and a method of forming are provided. The method includes forming an opening in a dielectric layer and an etch stop layer, wherein the opening extends only partially through the etch stop layer. The method also includes creating a vacuum environment around the device. After creating the vacuum environment around the device, the method includes etching through the etch stop layer to extend the opening and expose a first conductive feature. The method also includes forming a second conductive feature in the opening.

Claim (Index 4):
The method according to  claim 3 , wherein the opening in the dielectric layer is formed in an open air environment, and wherein the vacuum environment is maintained during the forming of the barrier layer and the seed layer.
