摘要： In some embodiments, the present disclosure relates to an image sensor integrated chip. The integrated chip has an image sensing element arranged within a substrate. A first dielectric is disposed in one or more trenches within a first side of the substrate. The one or more trenches laterally surround the image sensing element. The substrate includes a recessed portion arranged along the first side of the substrate and defined by second sidewalls of the substrate directly over the image sensing element. The second sidewalls of the substrate are angled to meet at a point disposed along a horizontal plane that intersects the first dielectric within the one or more trenches.

摘要： Various embodiments of the present application are directed to a narrow band filter with high transmission and an image sensor comprising the narrow band filter. In some embodiments, the filter comprises a first distributed Bragg reflector (DBR), a second DBR, a defect layer between the first and second DBRs, and a plurality of columnar structures. The columnar structures extend through the defect layer and have a refractive index different than a refractive index of the defect layer. The first and second DBRs define a low transmission band, and the defect layer defines a high transmission band dividing the low transmission band. The columnar structures shift the high transmission band towards lower or higher wavelengths depending upon a refractive index of the columnar structures and a fill factor of the columnar structures.

摘要： An image sensor includes a color filter array and a light receiving element. The color filter array includes plural repeating unit cells including first, second, and third unit cells. The first and second unit cells are adjacent to each other in a first direction, the second and third unit cells are adjacent to each other in a second direction transverse to the first direction. Each of the first, second, and third unit cells includes at least one first yellow filter configured to transmit a green component and a red component of incident light, and each of the first, second, and third unit cells does not comprise a red filter configured to transmit the red component of the incident light. The light receiving element is configured to convert the incident light transmitted by the color filter array into electric signals.
