  • Patent number: 11715722
    Abstract: Fabrication of a bondwire inductor between connection pads of a semiconductor package using a wire bonding process is disclosed herein. To that end, the bondwire inductor is fabricated by extending a bondwire connecting two connection pads of the semiconductor package around a dielectric structure, e.g., a dielectric post or posts, disposed between the connection pads a defined amount. In so doing, the bondwire inductor adds inductance between the connection pads, where the added inductance is defined by factors which at least include the amount the bondwire extends around the dielectric structure. Such additional inductance may be particularly beneficial for certain semiconductor devices and/or circuits, e.g., monolithic microwave integrated circuits (MMICs) to control or supplement impedance matching, harmonic termination, matching biasing, etc.
