    摘要: Embodiments of an image sensor pixel that includes a photosensitive element, a floating diffusion region, and a transfer device. The photosensitive element is disposed in a substrate layer for accumulating an image charge in response to light. The floating diffusion region is dispose in the substrate layer to receive the image charge from the photosensitive element. The transfer device is disposed between the photosensitive element and the floating diffusion region to selectively transfer the image charge from the photosensitive element to the floating diffusion region. The transfer device includes a buried channel device including a buried channel gate disposed over a buried channel dopant region. The transfer device also includes a surface channel device including a surface channel gate disposed over a surface channel region. The surface channel device is in series with the buried channel device. The surface channel gate has the opposite polarity of the buried channel gate.

    摘要: A backside illuminated image sensor includes a semiconductor layer and a trench disposed in the semiconductor layer. The semiconductor layer has a frontside surface and a backside surface. The semiconductor layer includes a light sensing element of a pixel array disposed in a sensor array region of the semiconductor layer. The pixel array is positioned to receive external incoming light through the backside surface of the semiconductor layer. The semiconductor layer also includes a light emitting element disposed in a periphery circuit region of the semiconductor layer external to the sensor array region. The trench is disposed in the semiconductor layer between the light sensing element and the light emitting element. The trench is positioned to impede a light path between the light emitting element and the light sensing element when the light path is internal to the semiconductor layer.

    摘要: A backside illuminated (“BSI”) complementary metal-oxide semiconductor (“CMOS”) image sensor includes a photosensitive region disposed within a semiconductor layer and a stress adjusting layer. The photosensitive region is sensitive to light incident on a backside of the BSI CMOS image sensor to collect an image charge. The stress adjusting layer is disposed on a backside of the semiconductor layer to establish a stress characteristic that encourages photo-generated charge carriers to migrate towards the photosensitive region.
