Abstract
A method includes forming a first magnetic material on a first surface of a conductive loop, forming a second magnetic material on a second surface of the conductive loop opposite the first surface to form an inductor, attaching a semiconductor die to a leadframe, and attaching the inductor to the leadframe with solder balls. The semiconductor die is between the inductor and the leadframe. The conductive loop: spans parallel to the leadframe; or is between the first magnetic material and the second magnetic material.
