Abstract
The present invention integrates an inductor into a semiconductor package by integrally forming inductive segments in the leadframe. The inductive segments may be connected directly to a lead of the leadframe, or indirectly to a lead or a bond pad on a semiconductor die via wirebonds to form an inductor. The inductance value for the resultant inductor is typically controlled by the point of contact for the wirebonds or the leads about the inductive segment. The inductance values may also be controlled by the shape and size of the inductive segments. The leadframe may be formed to support multiple inductive segments, and one or more configurations, including those using one or more die flags to support a like number of semiconductor die.
