Abstract:
The present disclosure is directed to a method of forming a polarization grating structure (e.g., polarizer) as part of a grid structure of a back side illuminated image sensor device. For example, the method includes forming a layer stack over a semiconductor layer with radiation-sensing regions. Further, the method includes forming grating elements of one or more polarization grating structures within a grid structure, where forming the grating elements includes (i) etching the layer stack to form the grid structure and (ii) etching the layer stack to form grating elements oriented to a polarization angle.

Claim (Index 1):
A semiconductor image sensor device, comprising:\n a semiconductor layer comprising one or more sensing regions configured to sense radiation; a grid structure, over the semiconductor layer, that comprises one or more cells respectively aligned to the one or more sensing regions; and a polarizing grating structure in the one or more cells of the grid structure, wherein the polarizing grating structure is configured to polarize light incoming to the semiconductor image sensor device.
