Abstract
For use with an integrated circuit having a substrate and an insulator coupled to the substrate, a micromagnetic device and method of manufacturing therefor. In one embodiment, the micromagnetic device includes an adhesive coupled to the insulator and a ferromagnetic core, coupled to the adhesive that forms a bond between the insulator and the ferromagnetic core, having an anisotropic property.
Claims19
For use with an integrated circuit having a substrate and an insulator coupled to said substrate, a micromagnetic device, comprising:
- an adhesive coupled to said insulator;
- and
- a ferromagnetic core, of said micromagnetic device, coupled to said adhesive that forms a bond between said insulator and said ferromagnetic core, having an anisotropic property.
A micromagnetic device for use with an integrated circuit having a substrate, comprising:
- a first conductive winding layer formed over said substrate;
- a first insulative layer formed over said first conductive winding layer;
- a metallic adhesive formed over said first insulative layer;
- and
- a ferromagnetic core, of said micromagnetic device, formed over said metallic adhesive and having an anisotropic property, said metallic adhesive forming a bond between said first insulative layer and said ferromagnetic core to secure said ferromagnetic core to said substrate.
