An integrated circuit structure comprises a first metal layer having first conductive features. A second metal layer has second conductive features. A via layer is in an insulating layer between the first metal layer and the second metal layer. First vias and second vias are formed in the insulating layer. The first vias have a first aspect ratio greater than a second aspect ratio of the second vias. A barrier-less metal partially fills the first vias and fills the second vias. A pure metal fills a remainder of the first vias.
