  • Patent number: 8288842
    Abstract: A method provides for dicing a wafer having a base material with a diamond structure. The wafer first undergoes a polishing process, in which a predetermined portion of the wafer is polished away from its back side. The wafer is then diced through at least one line along a direction at a predetermined offset angle from a natural cleavage direction of the diamond structure. A wafer is produced with one or more dies formed thereon with at least one of its edges at an offset angle from a natural cleavage direction of a diamond structure of a base material forming the wafer. At least one dicing line has one or more protection elements for protecting the dies from undesired cracking while the wafer is being diced along the dicing line.

    Abstract: A photonic device generates light from a full spectrum of lights including white light. The device includes two or more LEDs grown on a substrate, each generating light of a different wavelength and separately controlled. A light-emitting structure is formed on the substrate and apportioned into the two or more LEDs by etching to separate the light-emitting structure into different portions. At least one of the LEDs is coated with a phosphor material so that different wavelengths of light are generated by the LEDs while the same wavelength of light is emitted from the light-emitting structure.

  • Patent number: 7443638
    Abstract: Disclosed herein is a magnetoresistive structure, for example useful as a spin-valve or GMR stack in a magnetic sensor, and a fabrication method thereof. The magnetoresistive structure uses twisted coupling to induce a perpendicular magnetization alignment between the free layer and the pinned layer. Ferromagnetic layers of the free and pinned layers are exchange-coupled using antiferromagnetic layers having substantially parallel exchange-biasing directions. Thus, embodiments can be realized that have antiferromagnetic layers formed of a same material and/or having a same blocking temperature. At least one of the free and pinned layers further includes a second ferromagnetic layer and an insulating layer, such as a NOL, between the two ferromagnetic layers. The insulating layer causes twisted coupling between the two ferromagnetic layers, rotating the magnetization direction of one 90 degrees relative to the magnetization direction of the other.
