    摘要： An image sensor includes a substrate having a surface at which incident light is received. A pixel array is formed over and within the substrate. The pixel array includes a first and a second pixel arranged to receive light of different colors. The first pixel includes a photosensitive region formed in the substrate and has a first anti-reflective coating (ARC) layer formed over the photosensitive region. The first ARC layer has a first thickness that produces destructive interference above the first ARC layer in response to the incident light. The second pixel includes a photosensitive region formed in the substrate, and a second ARC layer formed over the photosensitive region that produces destructive interference above the second ARC layer in response to the incident light.

    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 (“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.

    摘要： An image sensor pixel includes a substrate, a first epitaxial layer, a collector layer, a second epitaxial layer and a light collection region. The substrate is doped to have a first conductivity type. The first epitaxial layer is disposed over the substrate and doped to have the first conductivity type as well. The collector layer is selectively disposed over at least a portion of the first epitaxial layer and doped to have a second conductivity type. The second epitaxial layer is disposed over the collector layer and doped to have the first conductivity type. The light collection region collects photo-generated charge carriers and is disposed within the second epitaxial layer. The light collection region is also doped to have the second conductivity type.
