Abstract: A method of forming a single layer inductive coil structure includes forming a first conductive coil on a substrate, forming an insulating layer by atomic layer deposition (ALD) over the first coil and the substrate, and forming one or more additional conductive coils on each of adjacent sides of the first coil insulated from the first coil and the substrate by the insulating layer. A method of forming a stacked layer inductive coil includes forming a cavity in a substrate, forming a first coil in the cavity wherein the cavity has an atomic layer deposition (ALD) layer, forming a second coil in the cavity adjacent to the first coil and separated by the ALD layer from the first coil, forming an insulating layer over the first and second coil, and forming a third coil on the insulating layer.

Abstract: A method and system for fabricating a piezoelectric multilayer are described. The method and system include providing conductive layers. Alternating conductive layers are electrically connected. A first plurality of alternating conductive layers is electrically isolated from a second plurality of alternating conductive layers. Piezoelectric layers are interleaved with the conductive layers. Apertures are provided in the piezoelectric layers. A first conductive plug electrically connects the first plurality of alternating conductive layers, includes a first plurality of segments, and is in apertures in the piezoelectric layers. Each of the first plurality of segments extends through one of the piezoelectric layers. A second conductive plug electrically connects the second plurality of alternating conductive layers, includes a second plurality of segments, and is in a second portion of the plurality of apertures.
