摘要: 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.

摘要: Methodologies and an apparatus for enabling magnetic shielding of stand alone MRAM are provided. Embodiments include placing MRAM dies and logic dies on a first surface of a mold frame; forming a top magnetic shield over top and side surfaces of the MRAM dies; forming a mold cover over the MRAM dies, FinFET dies and mold frame; removing the mold frame to expose a bottom surface of the MRAM dies and FinFET dies; and forming a bottom magnetic shield over the bottom surface of the MRAM dies.
