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.
