  • Patent number: 10692965
    Abstract: Methods of forming an inductor using dry processes are described. A cavity is laser drilled in an insulator. A first magnetic material layer is printed in the cavity. An Ag conductive ink is printed on the first magnetic material layer and a second magnetic material layer printed on the ink. The ink has a trace sandwiched between the first and second magnetic material layers that provides a majority of the inductance of the inductor. A protective insulating layer protects the second magnetic material layer from a wet chemistry solution when contacts are formed to the ink. The second magnetic material layer and ink are deposited in or on the cavity.

  • Patent number: 10672859
    Abstract: An apparatus and method of forming a magnetic inductor circuit. A substrate is provided and a first magnetic layer is formed in contact with one layer of the substrate. A conductive trace is formed in contact with the first magnetic layer. A sacrificial cooper layer protects the magnetic material from wet chemistry process steps. A conductive connection is formed from the conductive trace to the outside substrate, the conductive connection comprising a horizontal connection formed by in-layer plating. A second magnetic layer is formed in contact with the conductive trace. Instead of a horizontal connection, a vertical conductive connection can be formed that is perpendicular to the magnetic layers, by drilling a first via in a second of the magnetic layers, forming a buildup layer, and drilling a second via through the buildup layer, where the buildup layer protects the magnetic layers from wet chemistry processes.
