Abstract
A semiconductor device and an improved method for making it are described. The semiconductor device comprises a dual damascene interconnect that includes a conductive line. The device further includes a support structure that is spaced from the conductive line, and an insulating layer that is formed on the support structure and the conductive line. In the method for forming that device, a support structure is formed on a substrate, and an insulating layer is formed adjacent to it. Portions of the insulating layer are removed to form a via and a trench, which are filled with a conductive material to generate a dual damascene interconnect that includes a conductive line, wherein the conductive line is spaced from the support structure.
