Patent application numberDescriptionPublished
20100245645Solid-state image pickup apparatus and electronic apparatus - A solid-state image pickup apparatus includes a photoelectric converter, a wiring portion, a micro lens, and an adjustment film. The photoelectric converter is formed on a light incident side in a substrate. The wiring portion is formed on a side of the substrate that is opposite to the light incident side. The micro lens is formed on a light incident side of the photoelectric converter. The adjustment film adjusts variation of a light reception sensitivity in the photoelectric converter with respect to a wavelength of light that enters the photoelectric converter through the micro lens, and the adjustment film is formed between the photoelectric converter and the micro lens.09-30-2010

20100140453SOLID-STATE IMAGING DEVICE AND ELECTRONIC APPARATUS - Disclosed herein is a solid-state imaging device including: a pixel part configured to include a plurality of light receiving regions corresponding to different wavelengths; and an element isolator configured to separate the plurality of light receiving regions from each other in such a way that each of the light receiving regions in the pixel part has a size suited to an energy profile of light irradiation with a wavelength handled by the light receiving region.06-10-2010
20100157116SOLID-STATE IMAGE PICKUP DEVICE AND ELECTRONIC APPARATUS USING THE SAME - An embodiment of the invention provides a solid-state image pickup device, including a pixel portion in which a plurality of light receiving areas corresponding to different wavelengths, respectively, are disposed, and transistors used commonly to the plurality of adjacent light receiving areas in the pixel portion, and disposed so as to be brought near to a side of the light receiving area, corresponding to the shorter wavelength, of the plurality of adjacent light receiving areas.06-24-2010
20100187403Solid-state image pickup apparatus, electronic apparatus, and method of manufacturing a solid-state image pickup apparatus - Disclosed is a solid-state image pickup apparatus including a photoelectric converter formed on a substrate, a wiring portion formed above the photoelectric converter and constituted of multilayer wirings, and an insulating portion in which the multilayer wirings of the wiring portion are embedded, the insulating portion having a refractive index larger than a silicon oxide.07-29-2010
20100214454SOLID-STATE IMAGING DEVICE AND ELECTRONIC APPARATUS - Disclosed herein is a solid-state imaging device including a plurality of pixel units configured to be disposed in an imaging area in such a way that a plurality of pixels corresponding to different colors are treated as one unit, wherein the amount of shift of a position of each of the pixels in the pixel unit is so set as to differ depending on distance from a center of the imaging area to the pixel unit and a color.08-26-2010
20100230578Solid-state image pickup apparatus, method of manufacturing the same, and image pickup apparatus - A solid-state image pickup apparatus includes a substrate, a wiring layer, and a waveguide. The substrate is provided with a pixel array portion constituted of a plurality of pixels each having a photoelectric converter that converts incident light into an electrical signal. The wiring layer includes a plurality of wirings and an insulating layer that covers the plurality of wirings that are laminated above the substrate. The waveguide guides light to each of the photoelectric converters of the plurality of pixels, the waveguide being formed in the wiring layer. The waveguide is formed to have a waveguide exit end from which light exits the waveguide so that a distance between the waveguide exit end and a surface of the photoelectric converter that receives light from the waveguide become shorter, as wavelengths of light guided by the waveguide are longer.09-16-2010
20110139966SOLID-STATE IMAGING ELEMENT AND METHOD FOR MANUFACTURING THE SAME - A solid-state imaging element includes a light-receiving element portion disposed in a semiconductor layer, an insulating layer made of a material having a refractive index n06-16-2011
