This paper presents the design considerations for thin-film magnetic power inductors for integrated voltage regulator (IVR). Optimum design parameters for solenoid inductors are arrived at that maximize key performance metrics such as quality factor, inductor efficiency, inductance density, and operation frequency. A fabrication approach to integrate the solenoid inductor with thin-film magnetic material within the redistribution (RDL) layers is presented. Non-idealities that could impact the inductance performance are illustrated. Finally, electrical characterization of a set of test inductors is carried out and the results are presented.
