Claims
- 1. A high-Q inductor for high frequency,wherein the inductor has a plurality of inductor elements formed in a plurality of IC wiring layers respectively, wherein directions of magnetic fields generated by the respective inductor elements are substantially the same and wherein a drawing interconnect from one inductor element is formed in the IC wiring layer in which said one inductor element is formed.
- 2. A high-Q inductor for high frequency according to claim 1, wherein the plurality of inductor elements are in a spiral shape respectively and connected in parallel with each other, and the drawing interconnect is connected to a spiral center of the inductor element and drawn externally by being formed in one of the IC wiring layers, andthe spiral-shaped inductor element formed in the IC wiring layer used for the external drawing is cut off at positions where the drawing interconnect crosses, and cut-off ends of the inductor element are connected with each other by being connected with respective corresponding portions of the spiral-shaped inductor element formed in another one of the IC wiring layers.
