    Abstract: An image sensor device includes a semiconductor substrate having a front surface and a back surface; an array of pixels formed on the front surface of the semiconductor substrate, each pixel being adapted for sensing light radiation; an array of color filters formed over the plurality of pixels, each color filter being adapted for allowing a wavelength of light radiation to reach at least one of the plurality of pixels; and an array of micro-lens formed over the array of color filters, each micro-lens being adapted for directing light radiation to at least one of the color filters in the array. The array of color filters includes structure adapted for blocking light radiation that is traveling towards a region between adjacent micro-lens.
