  • Patent number: 10290775
    Abstract: A semiconductor light emitting device comprising a light emitting layer disposed between an n-type region and a p-type region is combined with a ceramic layer which is disposed in a path of light emitted by the light emitting layer. The ceramic layer is composed of or includes a wavelength converting material such as a phosphor. Luminescent ceramic layers according to embodiments of the invention may be more robust and less sensitive to temperature than prior art phosphor layers. In addition, luminescent ceramics may exhibit less scattering and may therefore increase the conversion efficiency over prior art phosphor layers.

  • Patent number: 7385259
    Abstract: A method of manufacturing a memory device addressing reliability and refresh characteristics through the use of a multilayered doped conductor, and a method making is described. The multilayered doped conductor creates a high dopant concentration in the active area close to the channel region. The rich dopant layer created by the multilayered doped conductor is less susceptible to depletion from trapped charges in the oxide. This improves device reliability at burn-in and lowers junction leakage, thereby providing a longer period between refresh cycles.

  • Patent number: 7382026
    Abstract: A contact connected to a word line is formed on a gate electrode of an access transistor of an SRAM cell. The contact passes through an element isolation insulating film to reach an SOI layer. A body region of a driver transistor and that of the access transistor are electrically connected with each other through the SOI layer located under the element isolation insulating film. Therefore, the access transistor is in a DTMOS structure having the gate electrode connected with the body region through the contact, which in turn is also electrically connected to the body region of the driver transistor. Thus, operations can be stabilized while suppressing increase of an area for forming the SRAM cell.
