  • Publication number: 20050008849
    Abstract: A magneto-resistive device is provided for contributing to a higher MR ratio and a reduced cleaning time for cleaning the surface of a cap layer. In the magneto-resistive device, a cap layer which serves as a protection layer is formed on a free layer which is the topmost layer of a magneto-resistive layer constituting a TMR devise. An upper electrode which is additionally used as an upper magnetic shield is electrically connected to the free layer through an upper metal layer. The cap layer comprised of a two-layer film made up of a conductive layer closer to the free layer and a topmost conductive layer. The conductive layer closer to the free layer is made of a material having higher oxygen bond energy than Ru, such as Zr, Hf, or the like. The topmost conductive layer is made of a material having lower oxygen bond energy, such as a noble metal or the like.
