Abstract:
1. A method for forming an inductor in a semiconductor integrated circuit, the method comprising: forming a first inductor line on a metallization dielectric layer, the first inductor line having terminal end pads; forming a dielectric layer over the first inductor line and the terminal end pads; forming a first opening in the dielectric layer to expose the first inductor line, wherein the length of the opening is substantially co-extensive with the first inductor line; filling the first opening with a conductive material to form a second inductor line that is in electrical communication and substantially co-extensive with the first inductor line and wherein the first and second inductor lines are cooperable to cause an inductive effect; forming second openings in the dielectric layer to expose the terminal end pads subsequent to forming the second inductor line; and filling the second openings with a conductive material to form contacts for the first and second inductor lines.
