    摘要: An image sensor and method of manufacture therefor includes a substrate having pixel control circuitry. Dielectric layers on the substrate include interconnects in contact with the pixel control circuitry and with pixel electrodes. An intrinsic layer is over the pixel electrodes and has a gap provided between the pixel electrodes. An intrinsic-layer covering layer is over the intrinsic layer and a transparent contact layer over the intrinsic-layer covering and the interconnects. The intrinsic, intrinsic-layer covering, and transparent contact layer interact in different combinations to provide a pixel isolation system for the image sensor.

    摘要: An image sensor. The image sensor array includes a substrate. An interconnect structure is formed adjacent to the substrate. An amorphous silicon electrode layer is adjacent to the interconnect structure. The amorphous silicon electrode layer includes electrode ion implantation regions between pixel electrode regions. The pixel electrode regions define cathodes of an array of image sensors. The electrode ion implantation regions provide physical isolation between the pixel electrode regions. The cathodes are electrically connected to the interconnect structure. An amorphous silicon I-layer is adjacent to the amorphous silicon electrode layer. The amorphous silicon I-layer forms an inner layer of each of the image sensors. A transparent electrode layer is formed adjacent to the image sensors. An inner surface of the transparent electrode is electrically connected to anodes of the image sensors and the interconnect structure. The amorphous silicon I-layer region can further include I-layer ion implantation regions that provide physical isolation between the inner layers of the image sensors. The I-layer ion implantation regions align with the electrode ion implantation regions. An amorphous silicon P-layer can be formed adjacent to the amorphous silicon I-layer. The amorphous silicon P-layer forms an outer layer of each of the image sensors. The amorphous silicon P-layer region can include P-layer ion implantation regions that provide physical isolation between the outer layers of the image sensors.

    摘要: An active pixel sensor having a transparent conductor that directly contacts a conductive element in an interconnection structure to electrically connect the transparent conductor to a pixel sensor bias voltage is provided. The active pixel sensor includes a semiconductor substrate, the interconnection layer, which is formed over the substrate, and a pixel interconnection layer formed over the interconnection layer. Photo sensors that include a pixel electrode, an I-layer, and may include a P-layer are formed over the pixel interconnection layer. The transparent conductor is formed over the photo sensors and the conductive element exposed on the surface of the interconnection layer.

    摘要: A self-aligned metal electrode sensor structure. The self-aligned metal electrode sensor structure includes a substrate which includes electronic circuitry. An interconnect structure is formed adjacent to the substrate. The interconnect structure includes conductive interconnect vias which pass through the interconnect structure. A sensor is formed adjacent to the interconnect structure. The sensor includes a pixel metallization section and a doped layer electrode. The pixel metallization section is electrically connected to the interconnect via. The pixel metallization section includes an outer surface which is substantially planar. The doped layer electrode includes an inner surface adjacent to the outer surface of the pixel metallization section. The entire inner surface of the doped layer electrode is substantially planar. A transparent conductive layer is formed adjacent to the sensor. The interconnect via and the transparent conductive layer electrically connect the electronic circuitry to the sensor. An embodiment includes the outer surface of the pixel metallization section having an outer surface area which is substantially equal to an inner surface area of the inner surface of the doped layer electrode. Another embodiment includes the outer surface of the pixel metallization section having an outer surface area which is less than an inner surface area of the inner surface of the doped layer electrode.
