Laminated magnetic materials for on-chip magnetic inductors/transformers
Abstract
A technique relates to a method of forming a laminated multilayer magnetic structure. An adhesion layer is deposited on a substrate. A magnetic seed layer is deposited on top of the adhesion layer. Magnetic layers and non-magnetic spacer layers are alternatingly deposited such that an even number of the magnetic layers is deposited while an odd number of the non-magnetic spacer layers is deposited. The odd number is one less than the even number. Every two of the magnetic layers is separated by one of the non-magnetic spacer layers. The first of the magnetic layers is deposited on the magnetic seed layer, and the magnetic layers each have a thickness less than 500 nanometers.
