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.

Patent number: 6802985Abstract: There is provided a method for fabricating electrical wirings capable of being manufactured with low cost and easily applied to large-scale substrates. A photosensitive ground resin film is formed on an insulating substrate by coating process. The ground resin film is subjected to exposure and development processes, by which a ground resin film patterned into a wiring pattern is obtained. Then, on the patterned ground resin film, a low-resistance metal film made of Cu is formed by electroless plating.Type: GrantFiled: August 25, 2000Date of Patent: October 12, 2004Assignee: Sharp Kabushiki KaishaInventors: Yoshimasa Chikama, Yoshihiro Izumi
