Abstract:
A high quality factor (Q) BEOL (back end of line) inductor element with a dynamically driven, patterned shield comprising:a BEOL inductor element fabricated spaced from a conductive substrate; a patterned conductive shield structure provided between the BEOL inductor element and the conductive substrate, wherein the patterned shield structure is dynamically driven to the same electrical potential as the BEOL inductor element, to reduce or eliminate parasitic capacitive coupling between the BEOL inductor element and the conductive substrate, and wherein the patterned shield structure is patterned to form a plurality of conductive segments which are selectively insulated from each other, such that eddy currents cannot flow from one conductive segment to an adjacent conductive segment, to prevent the flow of eddy currents in the patterned shield structure, and wherein the conductive segments are electrically connected together to be dynamically driven to the same electrical potential as the BEOL inductor element.
