The catalytic layer may be deposited by electroless deposition, electroplating, or chemical vapor deposition. In one embodiment, the catalytic layer may be deposited in the feature to act as a barrier layer to a subsequently deposited conductive material. In another embodiment, the catalytic layer may be deposited over a barrier layer. In yet another embodiment, the catalytic layer may be deposited over a seed layer deposited over the barrier layer to act as a “patch” of any discontinuities in the seed layer. Once the catalytic layer has been deposited, a conductive material, such as copper, may be deposited over the catalytic layer.Type: GrantFiled: January 28, 2002Date of Patent: November 30, 2004Assignee: Applied Materials, Inc.Inventors: Srinivas Gandikota, Chris R. McGuirk, Deenesh Padhi, Muhammad Atif Malik, Sivakami Ramanathan, Girish A. Dixit, Robin Cheung
