Claims20
An integrated circuit, comprising;
- a magnetic core located over a substrate;
- a winding around the magnetic core, the winding including first and second pluralities of coil members, the first plurality of coil members located between the magnetic core and the substrate, and the magnetic core located between the first and second pluralities of coil members,
- wherein at least one coil member of the first plurality of coil members, includes a slot that extends along the at least one coil member.
A method of forming an integrated circuit, comprising;
- forming a magnetic core layer over a substrate;
- forming first and second pluralities of coil members, the first plurality of coil members being located between magnetic core layer and the substrate, the magnetic core layer being located between the first and second pluralities of coil members;
- and
- forming a slot through at least one coil member of the plurality of coil members, the slot extending along a length direction of the at least one coil member.
