  • Semiconductor structure
    Patent number: 12154927
    Abstract: A semiconductor structure includes a semiconductor substrate, an interconnection structure, a color filter, and a first isolation structure. The semiconductor substrate includes a first surface and a second surface opposite to the first surface. The interconnection structure is disposed over the first surface, and the color filter is disposed over the second surface. The first isolation structure includes a bottom portion, an upper portion and a diffusion barrier layer surrounding a sidewall of the upper portion. A top surface of the upper portion of the first isolation structure extends into and is in contact with a dielectric layer of the interconnection structure.

  • Quinoxaline derivatives and their use in organic light-emitting diode device
    Patent number: 8460801
    Abstract: The present invention relates to novel quinoxaline derivatives and their use in an organic light-emitting diode device. The quinoxaline derivative is of luminescence and rigidity, can increase glass transition temperature (Tg) and has better thermal stability, and thus can be used as a hole transporting layer, a host or guest of an emitting layer or an electron transporting layer of an organic light-emitting diode device.
