Provided is a solid state imaging device including: a pixel portion where pixel sharing units are disposed in an array shape and where another one pixel transistor group excluding transfer transistors is shared by a plurality of photoelectric conversion portions; transfer wiring lines which are connected to the transfer gate electrodes of the transfer transistors of the pixel sharing unit and which are disposed to extend in a horizontal direction and to be in parallel in a vertical direction as seen from the top plane; and parallel wiring lines which are disposed to be adjacent to the necessary transfer wiring lines in the pixel sharing unit and which are disposed to be in parallel to the transfer wiring lines as seen from the top plane, wherein voltages which are used to suppress potential change of the transfer gate electrodes are supplied to the parallel wiring lines.

A pinned photodiode has a substrate having a first substrate side to which light is illuminated and a second substrate side opposite the first substrate side, a photoelectric conversion part including a first conductivity type semiconductor layer buried into the substrate and having a photoelectric conversion function for the received light and a charge accumulation function, a second conductivity type separation layer formed in the side portion of the first conductivity type semiconductor layer in the photoelectric conversion part, and one charge transfer gate part capable of transferring the charge accumulated in the photoelectric conversion part. The photoelectric conversion part, in at least a portion of the first conductivity type semiconductor layer, includes at least one second-conductivity type semiconductor layer forming at least one sub-area in a direction perpendicular to a normal line of the substrate and having a junction capacitance component together with the first conductivity type semiconductor layer.

There is provided an imaging device that includes photovoltaic type pixels that have photoelectric conversion regions generating photovoltaic power for each pixel depending on irradiation light; and an element isolation region that is provided between the photoelectric conversion regions of adjacent pixels and in a state of substantially surrounding the photoelectric conversion region.

Image intensifiers may include a photocathode that emits photoelectrons in proportion to the rate photons impact the photocathode. The photoelectrons are multiplied using a microchannel plate that includes a plurality of microchannels. Photoelectrons are scattered by the microchannel plate when the photoelectrons strike the surface of the microchannel plate rather than enter one of the microchannels. Electron scatter within an image intensifier results in a halo or bloom around bright or luminous objects. Halo or bloom may be minimized by reducing the electron scatter within the image intensifier. Deposition of an anti-scattering layer on the surface of the microchannel plate within the image intensifier can absorb photoelectrons that fail to enter a microchannel and may thus reduce the incidence of halo or bloom.

Various embodiments of the present technology may comprise methods and apparatus for a CCD image sensor. The image sensor may comprise a center channel disposed along a horizontal center line of the pixel array for collecting and transferring charge. The center channel is electrically coupled to a lateral overflow drain. In various embodiments, the image sensor may comprise a light shield under a gap between neighboring microlenses, such as a gap along the center line, to block light, such as to maintain a uniform, spatial sampling pattern across the device. In various embodiments, the image sensor may comprise a barrier region disposed between the center channel and the lateral overflow drain, for example to prevent charge from the lateral overflow drain being injected back into the center channel and adjacent pixels.

A pixel structure comprises an epitaxial layer (1) of a first conductivity type. A photo-sensitive element comprises a first region (4) of a second conductivity type and a second region (3) of the first conductivity type positioned between the epitaxial layer (1) and the first region (4). A charge storage node (2) is arranged to store charges acquired by the photo-sensitive element, or to form part of a charge storage element. A third region (2) of the second conductivity type is positioned between the charge storage node and the epitaxial layer. The pixel structure further comprises a charge-to-voltage conversion element (13) for converting charges from the charge storage node to a voltage signal and an output circuit (21, 22) for selectively outputting the voltage signal from the pixel structure.
