  • Publication number: 20050151128
    Abstract: A device comprising a number of different wavelength-selective active-layers arranged in a vertical stack, having band-alignment and work-function engineered lateral contacts to said active-layers, consisting of a contact-insulator and a conductor-insulator. Photons of different energies are selectively absorbed in or emitted by the active-layers. Contact means are arranged separately on the lateral sides of the vertical stack for injecting charge carriers into the photon-emitting layers and extracting charge carriers generated in the photon-absorbing layers. The device can be used for various applications for light emission or light absorption. The stack of active layers may also include top and bottom electrodes whereby the device can also be operated as a FET device.

The small light emitting element has the luminescent area of about 0.5 mm square, and each small light emitting element is disposed at a position corresponding to each clearance N1 in the scanning direction. Because the large light emitting elements and the small light emitting elements do not overlap each other in the scanning direction, even if the light emitting element array comes close to a thermosensitive recording paper, there becomes no uneven distribution of light quantity of the light emitting element array in the scanning direction.

  • Publication number: 20050151168
    Abstract: Reliability of a semiconductor device having a nonvolatile memory comprising first through third gate electrodes is enhanced. With a flash memory having first gate electrodes (floating gate electrodes), second gate electrodes (control gate electrodes) and third gate electrodes, isolation parts are formed in a self-aligned manner against patterns of a conductor film for forming the third gate electrodes by filling up the respective isolation grooves and a gate insulator film for select nMISes in a peripheral circuit region is formed prior to the formation of the isolation parts. By so doing, deficiency with the gate insulator film for the select nMISes, caused by stress occurring to the isolation parts, can be reduced. Further, with the semiconductor device including the case of stacked memory cells, the patterns of the conductor film for forming the third gate electrodes, serving as a mask for forming the isolation parts in the self-aligned manner, can be formed without misalignment against channels.

  • Publication number: 20050151169
    Abstract: In a photosensitive part 10, arranged from pixels A aligned in n rows and m columns, supply wiring lines 13a and 13b, which are electrically connected and apply transfer voltages to transfer electrodes 12a to 12d, formed of polycrystalline silicon, are installed so as to cover parts of the top surfaces of light-shielded pixels D. Dead zones for installing supply wiring lines, which existed priorly at the respective end parts in a horizontal direction of a photosensitive part, can thereby be eliminated and the photosensitive part can be made wide. Also, in the case where a plurality of the solid-state image pickup devices are used upon being made adjacent each other in the horizontal direction, parts at which image pickup is not carried out can be lessened. Also, the amount of lowering of the amounts of incident light on light-shielded pixels D can be corrected based on the output signals from light-shielded pixels D or other pixels A.

  • Publication number: 20050151171
    Abstract: Junction field effect transistors (JFETs) can be fabricated with an epitaxial layer that forms a sufficiently thick channel region to enable the JFET for use in high voltage applications (e.g., having a breakdown voltage greater than about 20V). Additionally or alternatively, threshold voltage (VT) implants can be introduced at one or more of the gate, source and drain regions to improve noise performance of the JFET. Additionally, fabrication of such a JFET can be facilitated forming the entire JFET structure concurrently with a CMOS fabrication process and/or with a BiCMOS fabrication process.
