Abstract
An image sensor includes a pixel array with a plurality of pixels arranged in a semiconductor layer. A color filter array including a plurality of groupings of filters is disposed over the pixel array. Each filter is optically coupled to a corresponding one of the plurality of pixels. Each one of the plurality of groupings of filters includes a first, a second, a third, and a fourth filter having a first, a second, the second, and a third color, respectively. A metal layer is disposed over the pixel array and is patterned to include a metal mesh having mesh openings with a size and pitch to block incident light having a fourth color from reaching the corresponding pixel. The metal layer is patterned to include openings without the metal mesh to allow the incident light to reach the other pixels.
