  • Patent number: 9799639
    Abstract: Embodiments of mechanisms for forming power gating cells and virtual power circuits on multiple active device layers are described in the current disclosure. Power gating cells and virtual power circuits are formed on separate active device layers to allow interconnect structure for connecting with the power source be formed on a separate level from the interconnect structure for connecting the power gating cells and the virtual power circuits. Such separation prevents these two types of interconnect structures from competing for the same space. Routings for both types of interconnect structures become easier. As a result, metal lengths of interconnect structures are reduced and the metal widths are increased. Reduced metal lengths and increased metal widths reduce resistance, improves resistance-capacitance (RC) delay and electrical performance, and improves interconnect reliability, such as reducing electro-migration.

  • Patent number: 9748522
    Abstract: The invention relates to an illumination system comprising a light emitting device and a beam shaping element for generating an angular distribution of the light emitted from the illumination system. The beam shaping element is configured for recycling at least a part of the light emitted from a light emitting surface of the light emitting device via reflection back towards the light emitting surface. The illumination system further comprises a diffuser arranged substantially parallel to the light emitting surface for diffusing at least part of the recycled light. The diffuser is constituted of a translucent diffuser and/or a diffusely reflective electrode layer of the light emitting device. Limiting the angular distribution by recycling light, using the beam shaping element for recycling light via reflection, reduces glare when the illumination system is used in general lighting applications.
