  • Patent number: 7964902
    Abstract: First diffusion region constituting a photodiode in each pixel stores carriers generated according to incident light. Second diffusion region is formed at a surface of the first diffusion region to cover a peripheral part of the first diffusion region. In the peripheral part of the first diffusion region, crystal defects tend to occur by a process of forming an isolation region and a gate electrode, so that dark current noise tends to occur. The second diffusion region functioning as a protection layer prevents crystal defects in a manufacturing process. The second diffusion region isn't formed on a center of the surface of the first diffusion region where crystal defects don't tend to occur. In the first diffusion region where the second diffusion region isn't formed, the thickness of a depletion layer increases, which improves light detection sensitivity. This improves detection sensitivity of the photodiode without increasing the dark current noise.

  • Patent number: 7911034
    Abstract: A method for patterning CNTs on a wafer wherein a CNT layer is provided on a substrate, a hard mask film is deposited on the CNT layer, a BARC layer (optional) is coated on the hard mask film, and a resist is patterned on the BARC layer (or directly on the hard mask film if the BARC layer is not included). Then, the resist pattern is effectively transferred to the hard mask film by etching the BARC layer (if provided) and etching partly into, but not entirely through, the hard mask film (i.e., etching is stopped before reaching the CNT layer). Then, the resist and the BARC layer (if provided) is stripped, and the hard mask pattern is effectively transferred to the CNTs by etching away (preferably by using C1, F plasma) the portions of the hard mask which have been already partially etched away.

  • Patent number: 7888807
    Abstract: For electrically connecting a wiring formed on one surface of an insulating substrate such as an FPC to an individual electrode arranged facing the other surface of the substrate, firstly, a through hole and a notch are formed by irradiating a laser beam from above onto the FPC. Next, the FPC is arranged to be positioned such that the individual electrode, the through hole and the notch are overlapped in a plan view. Next, an electroconductive liquid droplet having a diameter greater than a width of the notch is jetted, toward an area formed with the notch, from the one surface side of the FPC. The landed electroconductive liquid droplet flows along the notch in a thickness direction of the substrate due to an action of a capillary force and reaches assuredly to the individual electrode, thereby electrically connecting the wiring and electrode arranged sandwiching the insulating substrate assuredly.

  • Patent number: 7888754
    Abstract: An MEMS transducer is constituted of a diaphragm, a plate, a support structure for supporting the diaphragm and the plate with a gap layer surrounded by an interior wall, an electrode film (e.g. a pad conductive film) for covering a contact hole formed in the support structure, and a protective film (e.g. a pad protective film) which is formed on the support structure externally of the interior wall so as to cover the side surface of the electrode film having low chemical stability. The protective film is formed in the limited area including a part of the surface of the electrode film except for its center portion and the surrounding area of the electrode film. This allows the protective film to use materials having high membrane stress such as silicon nitride or silicon nitride oxide.
