We demonstrated multi-storied photodiode CMOS image sensor with a wire grid layer to capture color image and polarization information at the same time in the exact same frame composed of the two types of images. This image sensor consists of stacked two layers of photodiode (PD) arrays and a wire grid layer between PD arrays. This sensor detects not only optical image with top PD array but also polarization information with bottom PD one. In this paper we report the characteristics of PD array which detect polarization information. In the sensor wire grid layer consist metal layer on the semiconductor substrate and the polarized light extinction ratio is over three at 640nm wave length with 200mm/200mm metal wire grid line /space. |
