Abstract:
A passivated magneto-resistive bit structure characterized by:a substrate; a magneto-resistive bit provided upon said substrate, the magneto-resistive bit having a top surface and side walls; an etch stop barrier layer provided upon at least part of the top surface of said bit, said etch stop barrier layer having a top surface and side walls; a dielectric side wall spacer provided along at least part of the side walls of said bit, the dielectric spacer extending laterally away from said magneto-resistive bit; and a contact layer provided over at least part of said etch stop barrier layer and over at least part of the dielectric side wall spacer for providing an electrical connection to said magneto-resistive bit via the etch stop barrier layer.
