A method for forming conductive contacts in a dielectric layer is provided. Partial vias are etched into the dielectric layer through a via mask. Trenches are etched into the dielectric layer through a trench mask, wherein the etching the trenches completes and over etches the vias to widen bottoms of the vias. Tops of the trenches or vias are rounded.
