US 10,593,449 B2 · Magnetic inductor with multiple magnetic layer thicknesses

Abstract

Embodiments are directed to a method of forming a laminated magnetic inductor and resulting structures having multiple magnetic layer thicknesses. A first magnetic stack having one or more magnetic layers alternating with one or more insulating layers is formed in a first inner region of the laminated magnetic inductor. A second magnetic stack is formed opposite a major surface of the first magnetic stack in an outer region of the laminated magnetic inductor. A third magnetic stack is formed opposite a major surface of the second magnetic stack in a second inner region of the laminated magnetic inductor. The magnetic layers are formed such that a thickness of a magnetic layer in each of the first and third magnetic stacks is less than a thickness of a magnetic layer in the second magnetic stack.
