Image sensors including a semiconductor substrate, a plurality of photo detecting elements, a dielectric layer, a plurality of color filters, and a plurality of micro lenses. The photo detecting elements may be in the semiconductor substrate and may convert an incident light into an electric signal. The dielectric layer may be on the semiconductor substrate and may include a plurality of photo blocking regions on regions between the photo detecting elements. The color filters may be on the dielectric layer and may be disposed corresponding to the plurality of photo detecting elements, respectively. The micro lenses may be on the plurality of color filters and may be disposed corresponding to the plurality of photo detecting elements, respectively.

Image sensors

A color filter array includes a plurality of white filters, a plurality of yellow filters, a plurality of cyan filters and a plurality of green filters. The plurality of white filters transmits incident light. The plurality of yellow filters transmits a green component and a red component of the incident light. The plurality of cyan filters transmits the green component and a blue component of the incident light. The plurality of green filters transmits the green component of the incident light. An image sensor including the color filter array has high sensitivity and high SNR by increasing transmittance of the incident light.

Color filter array, image sensor including the color filter array and system including the image sensor

A pixel cell includes a substrate, an epitaxial layer, and a photo converting device in the epitaxial layer. The epitaxial layer has a doping concentration profile of embossing shape, and includes a plurality of layers that are stacked on the substrate. The photo converting device does not include a neutral region that has a constant potential in the vertical direction. Therefore, the image sensor including the pixel cell has high quantization efficiency, and a crosstalk between photo-converting devices is decreased.
