Abstract:
1. A method of making at least one high density planarized inductor having interwound conductive elements comprising the steps of: forming a first conductive element over an insulator on a substrate of a semiconductor device, the first conductive element having a first coil shape with a first plurality of coils in which the conductive element has a width and there exists a spacing adjacent the width that causes the plurality of coils; forming an insulator over the first conductive element, the insulator having sidewalls and creating therebetween a void with a void width that has a second coil shape; and creating a second conductive element on the substrate, the second conductive element having the second coil shape with a second plurality of coils, wherein the second plurality of coils have the second coil shape that is that of the void and the void width, wherein each of the at least one high density planarized inductor comprises one or more of the first and second conductive elements.
