Abstract
A mechanism is provided for an integrated laminated magnetic device. A substrate and a multilayer stack structure form the device. The multilayer stack structure includes alternating magnetic layers and diode structures formed on the substrate. Each magnetic layer in the multilayer stack structure is separated from another magnetic layer in the multilayer stack structure by a diode structure.

A method for fabricating an integrated laminated magnetic device, comprising:
- forming a seed layer on a substrate;
- forming a mask structure over the seed layer, wherein the mask structure exposes an exposed portion of the seed layer that defines a device region;
- electroplating a first magnetic layer on the exposed portion of the seed layer within the device region using the seed layer as an electrical cathode or anode;
- forming a diode structure on the first magnetic layer in the device region;
- electroplating a second magnetic layer on the diode structure within the device region using the seed layer as the electrical cathode or anode;
- wherein the first magnetic layer is electrically connected to the second magnetic layer by the diode structure being in a forward bias direction;
- and
- wherein a combination of the first magnetic layer, the diode structure, and the second magnetic layer form a sandwich.
