Abstract
A passivated magneto-resistive bit structure is disclosed in which surfaces subject to oxidation or corrosion are protected. In one embodiment a bit structure is encapsulated by means of an etch stop barrier material. In another embodiment an etch stop barrier material protects the top of a bit structure and dielectric spacers protect the side walls.
