    摘要: Embodiments relate to xMR sensors, including giant magnetoresistive (GMR), tunneling magnetoresistive (TMR) or anisotropic magnetoresistive (AMR), and the configuration of xMR strips within xMR sensors. In an embodiment, an xMR strip includes a plurality of differently sized and/or differently oriented serially connected portions. In another embodiment, an xMR strip includes a varying width or other characteristic. Such configurations can address discontinuities associated with conventional xMR sensors and improve xMR sensor performance.

    摘要: An annular microstructure element, in particular an annularly arranged monolayer or multilayer thin film, is formed over a substrate (S), e.g., for use in a magnetoresistive memory. To that end, a masking layer is applied over the substrate. An opening (C) is etched into the masking layer, so that a partial region of the surface is uncovered. The etching operation is performed in such a way that the opening (C) is formed with an overhang (B). The overhang at least partially shades the uncovered surface from an incident particle beam (TS). A particle beam (TS) is directed at the substrate (S) at an oblique angle (α) of incidence. In this case, the substrate (S) is rotated relative to the directed particle beam (TS). From the particle beam, material is thereby deposited annularly on the uncovered surface for the purpose of forming a hole-like microstructure element (R).

    摘要: A method of forming a magnetic stack and a structure for a magnetic stack of a resistive memory device. A crystallization inhibiting layer is formed over the free layer of a magnetic stack, improving thermal stability. The crystallization inhibiting layer comprises an amorphous material having a higher crystallization temperature than the crystallization temperature of the free layer material. The crystallization inhibiting layer inhibits the crystallization of the underlying free layer, providing improved thermal stability for the resistive memory device.

    摘要: An improved scalable, resistive element for use in a semiconductor device that can be produced with a small feature size and precise resistance is provided by the present invention. The resistive element includes a base layer positioned on top of a metal line. A seed layer of is deposited on top of the base layer. A thin barrier layer of Al is deposited on top of the seed layer and oxidized. A non-magnetic metal layer is then deposited on top of the barrier layer. The base layer and the non-magnetic metal layer form electrodes on either side of the barrier layer. The barrier layer is thin enough that a tunneling current can travel between the electrodes. The resulting resistive element may be constructed with a high resistance and a very small feature size.
