Patent number: 8946896Abstract: A dielectric layer overlies a semiconductor substrate. The substrate has components and appropriate contacts formed therein. The dielectric layer electrically insulates the substrate and components from overlying conductive interconnect layers. A barrier layer is arranged over the dielectric layer to isolate the interconnect layers from other structures. A copper layer is then deposited over the barrier layer and thick interconnect lines having a first width and a first height are realized. Then, the barrier layer is etched using one of many alternative techniques. The barrier layer has a second width and a second height wherein the second width of the barrier liner is selected to be greater than the first width of the thick copper interconnect.Type: GrantFiled: December 31, 2009Date of Patent: February 3, 2015Assignee: STMicroelectronics, Inc.Inventors: David Moreau, Jerome Ciavatti
