Abstract

Aspects of the present disclosure provide an integrated circuit package having an inductive element with a magnetic core. An example integrated circuit package generally includes a semiconductor die, a redistribution layer, and a magnetic core. The semiconductor die includes a metal layer having first conductive traces and conductive pillars coupled to and extending from the metal layer. The redistribution layer is disposed below the semiconductor die and includes second conductive traces. A portion of the first conductive traces, a portion of the conductive pillars, and a portion of the second conductive traces are arranged to form an inductive element disposed below a portion of the semiconductor die. The magnetic core is disposed in the inductive element.
