Abstract
Methods of magnetically shielding an MRAM structure on all six sides in a thin wire or thin flip chip bonding package and the resulting devices are provided. Embodiments include forming a first metal layer embedded between an upper and a lower portion of a PCB substrate, the first metal layer having a pair of metal filled vias laterally separated; attaching a semiconductor die to the upper portion of the PCB substrate between the pair of metal filled vias; connecting the semiconductor die electrically to the PCB substrate through the pair of metal filled vias; removing a portion of the upper portion of the PCB substrate outside of the pair of metal filled vias down to the first metal layer; and forming a second metal layer over and on four opposing sides of the semiconductor die, the second metal layer landed on the first metal layer.
