Abstract
An inductor structure comprising a substrate; a plurality of insulation layers on the substrate; a first spiral electric conductive coil positioned in the insulation layers to form an inductor having a first direction of magnetic field; a second spiral electric conductive coil positioned in the insulation layers to form an inductor having a second direction of magnetic field, in which, the two or more inductors are independently positioned in a same 3-D space and have a good integration.
Claims12
An inductor structure, comprising:
- a substrate;
- a plurality of insulation layers on the substrate;
- a first spiral conductive coil disposed in the insulation layers to form an inductor generating a magnetic field in a first direction;
- and
- a second spiral conductive coil disposed in the insulation layers to form an inductor generating a magnetic field in a second direction;
- wherein the first direction and the second direction are not parallel to each other.
