Abstract
A semiconductor structure for providing isolations for on-chip inductors comprises a semiconductor substrate, one or more on-chip inductors formed above the first semiconductor substrate, a plurality of through-silicon-vias formed through the first semiconductor substrate in a vicinity of the one or more on-chip inductors, and one or more conductors coupling at least one of the plurality of through-silicon-vias to a ground, wherein the plurality of through-silicon-vias provide isolations for the one or more on-chip inductors.
