Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A method of making a slow wave inductive structure, the method comprising:
forming a first conductive winding over a first substrate;
forming a switch in a second substrate different from the first substrate;
forming an inter-level via (ILV) in the second substrate;
forming a second conductive winding over the second substrate, wherein the second conductive winding comprises a conductive line around a central opening, the switch is electrically connected to the second conductive winding on a first side of the opening, and the ILV is electrically connected to the second conductive winding on a second side of the opening opposite the first side; and
bonding the second substrate to the first substrate, wherein bonding the second substrate comprises electrically connecting the first conductive winding to the switch.
