    Abstract: 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.

    Abstract: An image sensor chip having a sidewall interconnect structure to bond and/or electrically couple the image sensor chip to a package substrate is provided. The image sensor chip includes a substrate supporting an integrated circuit (IC) configured to sense incident light. The sidewall interconnect structure is arranged along a sidewall of the substrate and electrically coupled with the IC. A method for manufacturing the image sensor chip and an image sensor package including the image sensor chip are also provided.

    Abstract: An image sensor package is provided. The image sensor package comprises a package substrate, and an image sensor chip arranged over the package substrate. The integrated circuit device further comprises a protection layer overlying the image sensor chip having a planar top surface and a bottom surface lining and contacting structures under the protection layer, and an on-wafer shield structure spaced around a periphery of the image sensor chip. The height of the image sensor package can be reduced since a discrete cover glass or an infrared filter and corresponding intervening materials are no longer needed since being replaced by the build in protection layer. The size of the image sensor package can be reduced since a discrete light shield and corresponding intervening materials are no longer needed since being replaced by the build in on wafer light shield structure.
