  • Patent number: 11963457
    Abstract: A layered thin film device, such as a MTJ (Magnetic Tunnel Junction) device can be customized in shape by sequentially forming its successive layers over a symmetrically curved electrode. By initially shaping the electrode to have a concave or convex surface, the sequentially formed layers conform to that shape and acquire it and are subject to stresses that cause various crystal defects to migrate away from the axis of symmetry, leaving the region immediately surrounding the axis of symmetry relatively defect free. The resulting stack can then be patterned to leave only the region that is relatively defect free.

  • Publication number: 20230371398
    Abstract: A magnetic tunneling junction (MTJ) structure is described. The MJT structure includes a stress modulating layer on a first electrode layer, where a material of the stress modulating layer is different from a material of the first electrode layer. The MJT structure further includes a MTJ material stack on the stress modulating layer. And the MJT structure further includes a second electrode layer on the MTJ material stack. The stress modulating layer reduces crystal growth defects and interfacial defects during annealing and improve the interface lattice epitaxy. This will improve device performance.

  • Patent number: 11430945
    Abstract: A method for fabricating an improved magnetic tunneling junction (MTJ) structure is described. A bottom electrode is provided on a substrate. A MTJ stack is deposited on the bottom electrode. A top electrode is deposited on the MTJ stack. A first stress modulating layer is deposited between the bottom electrode and the MTJ stack, or a second stress modulating layer is deposited between the MTJ stack and the top electrode, or both a first stress modulating layer is deposited between the bottom electrode and the MTJ stack and a second stress modulating layer is deposited between the MTJ stack and the top electrode. The top electrode and MTJ stack are patterned and etched to form a MTJ device. The stress modulating layers reduce crystal growth defects and interfacial defects during annealing and improve the interface lattice epitaxy. This will improve device performance.

  • Publication number: 20220236304
    Abstract: Vertical probe arrays having angled guide plates are provided. With this configuration, the probes can be straight conductors (when mechanically undeformed) and the mechanical bias provided by the angled guide plates can ensure the probes have a well-defined deformation when the probe array make contact to the device under test. This allows the use of straight conductors as probes without suffering from probe shorting and mechanical interference caused by straight probes buckling in unpredictable directions when vertically compressed.

  • Patent number: 10623330
    Abstract: A distributed bandwidth allocation system a distributed bandwidth limiter, a first throttler, and a second throttler. The distributed bandwidth limiter receives first usage data for a first entity and usage data for a second entity. Based on the first usage data, second usage data, and a total bandwidth allocation, the distributed bandwidth limiter determines a first bandwidth allocation specifying bandwidth available for network traffic for the first entity and a second bandwidth allocation that specifies bandwidth available for network traffic for the second entity, wherein a sum of the first bandwidth allocation and the second bandwidth allocation does not exceed the total bandwidth allocation. The first bandwidth allocation and the second bandwidth allocation are provided to respective throttlers than manage traffic for the first and second entities.
