20100207225 | Solid-state imaging device, electronic apparatus, and method for manufacturing the same - A solid-state imaging device includes: photoelectric conversion elements disposed on an imaging surface of a substrate, receiving light incident on a light receiving surface and performing photoelectric conversion to produce a signal charge; electrodes interposed between the photoelectric conversion elements; and light blocking portions provided above the electrodes and interposed between the photoelectric conversion elements. The light blocking portions include an electrode light blocking portion formed to cover the corresponding electrode, and a pixel isolation and light blocking portion protruding convexly from the upper surface of the electrode light blocking portion. The photoelectric conversion elements are arranged at first pitches on the imaging surface. The electrode light blocking portions and the pixel isolation and light blocking portions in the light blocking portions are arranged at second and third pitches, respectively, on the imaging surface. At least the third pitch increases with distance from the center toward the periphery of the imaging surface. | 08-19-2010 |

20140063303 | IMAGE SENSOR, IMAGING APPARATUS, AND APPARATUS AND METHOD FOR MANUFACTURING IMAGE SENSOR - There is provided an image sensor having a plurality of pixels, each pixel including a light receiving portion configured to receive incident light, a waveguide configured to guide the incident light from a light incident surface to the light receiving portion, and a light shielding portion disposed between the light incident surface and the light receiving portion, for blocking the incident light. The light shielding portion has an opening formed near a light emitting surface of the waveguide. The light receiving portion receives the incident light passing through the waveguide and the opening. A width of a core of the waveguide and a width of the opening are set so that the widths increase as a wavelength of the light incident on a pixel becomes longer. | 03-06-2014 |
