摘要:
MTJ stack structures for an MRAM device include an MTJ stack having a pinned ferromagnetic layer over a pinning layer, a tunneling barrier layer over the pinned ferromagnetic layer, a free ferromagnetic layer over the tunneling barrier layer, a conductive oxide layer over the free ferromagnetic layer, and an oxygen-based cap layer over the conductive oxide layer.
