Abstract
An integrated circuit package and method of fabrication are described. The integrated circuit package includes a lead frame having a first surface and a second opposing surface and a semiconductor die having a first, active surface in which circuitry is disposed and a second opposing surface attached to the first surface of the lead frame. A magnet attached to the second surface of the lead frame has a non-contiguous central region and at least one channel extending laterally from the central region. An overmold material forms an enclosure surrounding the magnet, semiconductor die, and a portion of the lead frame.
