Claim Text:
1. An inductor assembly comprising: at least one helical inductive component comprising: a plurality of conductive line layers having conductive lines, wherein each of the plurality of conductive line layers comprises a pair of conductive lines parallel to each other and perpendicular to a pair of conductive lines in a next adjacent conductive line layer; and a plurality of vias configured to couple said conductive lines of adjacent layers from two or more of said plurality of conductive line layers such that a smallest spacing between two adjacent parallel conductive lines aligned one above the other, in different conductive line layers from each other, is two or more times a distance between respective bottom surfaces of two adjacent conductive line layers of said plurality of conductive line layers; wherein said at least one helical inductive component comprises a first helical inductive component and a second helical inductive component, at least a portion of said first helical inductive component is disposed onto a first integrated chip (IC) die and at least a portion of said second helical inductive component is disposed onto a second IC die that is vertically stacked onto the first IC die.
