Magnetic microinductors for integrated circuit packaging

摘要

Magnetic microinductors formed on semiconductor packages are provided. The magnetic microinductors are formed as one or more layers of coplanar magnetic material on a package substrate. Conducting vias extend perpendicularly through the plane of the magnetic film. The magnetic film is a layer of isotropic magnetic material or a plurality of layers of anisotropic magnetic material having differing hard axes of magnetization.
