Inductive elements comprising anisotropic media and biasing coils for magnetically biasing thereof and methods of manufacture and operation for use in applications such as microelectronics. Application of an electrical current through the bias coils generates a magnetic field that biases the magnetic material such that a desirable orientation of anisotropy is achieved throughout the magnetic core and enables modulation of the inductive response of the device. Electrical conductors coupled to interconnects are magnetically coupled to magnetic core layers to produce self and/or mutual inductors.

Apparatus and methods for magnetic core inductors with biased permeability

A method of forming an inductor assembly includes depositing a magnetic core on a planar substrate lying in a core plane, forming an inductor coil that generates a magnetic field that passes through the magnetic core in a closed loop parallel to the core plane, and annealing the magnetic core while applying an external magnetic field that passes through the magnetic core in a radial direction to permanently fix the easy axis of magnetization parallel to the radial direction. As a result, the hard axis of magnetization of the magnetic core is permanently oriented in a generally circular closed path parallel to the closed loop of the inductor's magnetic field.

Manufacturing methods for magnetic core inductors with biased permeability

Methods of manufacturing are disclosed for an inductor that includes a magnetic core lying in a core plane. The magnetic core includes a vertical laminated structure with respect to the core plane of alternating ferromagnetic vertical layers and insulator vertical layers. An easy axis of magnetization can be permanently or semi-permanently fixed in the ferromagnetic vertical layers along a first axis orthogonal to the core plane. A hard axis of magnetization can be permanently or semi-permanently induced in the ferromagnetic vertical layers, the hard axis of magnetization lying in a plane that is orthogonal to the first axis.

Methods of manufacturing integrated magnetic core inductors with vertical laminations

An inductor includes a magnetic core lying in a core plane. The magnetic core includes a vertical laminated structure with respect to the core plane of alternating ferromagnetic vertical layers and insulator vertical layers. An easy axis of magnetization can be permanently or semi-permanently fixed in the ferromagnetic vertical layers along an axis orthogonal to the core plane. Methods of manufacturing same are also disclosed.
