Abstract
An inductive device may be provided, including a first winding layer, a second winding layer arranged over the first winding layer and connected to the first winding layer to form a plurality of turns around a first axis, and a magnetic core arranged vertically between the first winding layer and the second winding layer. The magnetic core may include a portion entirely over the first winding layer and entirely under the second winding layer, where this portion may include a magnetic segment and a non-magnetic segment arranged laterally adjacent to each other along the first axis.

An inductive device comprising:
- a first winding layer;
- a second winding layer arranged over the first winding layer and connected to the first winding layer to form a plurality of turns around a first axis;
- and
- a magnetic core arranged vertically between the first winding layer and the second winding layer, wherein the magnetic core comprises a portion entirely over the first winding layer and entirely under the second winding layer;
- wherein the portion of the magnetic core comprises a magnetic segment and a non-magnetic segment arranged laterally adjacent to each other along the first axis.
A method of fabricating an inductive device, the method comprising:
- forming a first winding layer;
- forming a second winding layer over the first winding layer, wherein the second winding layer is connected to the first winding layer to form a plurality of turns around a first axis;
- and
- forming a magnetic core vertically between the first winding layer and the second winding layer, wherein the magnetic core comprises a portion entirely over the first winding layer and entirely under the second winding layer;
- wherein the portion of the magnetic core comprises a magnetic segment and a non-magnetic segment arranged laterally adjacent to each other along the first axis.
