Abstract:
1. A CMOS image sensor comprising: an array of active pixels disposed on a semiconductor substrate, each active pixel of the array comprising a respective photodiode, the array to provide signals associated with an image focused on the array; a controller disposed on the semiconductor substrate and coupled to the array to provide correlated double-sampling of signals associated with the image; an analog-to-digital converter disposed on the semiconductor substrate and coupled to the array to convert analog signals associated with the image into digital signals associated with the image; a digital-to-analog converter disposed on the semiconductor substrate and coupled to the analog-to-digital converter; and a layer of material disposed over the array, the controller, the analog-to-digital converter, and the digital-to-analog converter, wherein the layer of material is patterned over the array and the layer of material is unpatterned over regions outside the array to primarily block light from the regions outside the array.
