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 9):
A semiconductor image sensor, comprising:\n one or more polarizing grating structures comprising grating elements aligned to a light polarization angle, wherein the one or more polarization grating structures are disposed in cells defined by a grid structure; a semiconductor layer with sensing regions configured to sense radiation entering the semiconductor layer from the grid structure, wherein the semiconductor layer is disposed below the grid structure so that each of the cells of the grid structure is aligned to a sensing region of the semiconductor layer; and a micro-lens over each cell of the grid structure.
