摘要: A method of manufacturing an image sensor is provided. In this method, a photoelectric conversion unit may be formed within a semiconductor substrate, wherein the semiconductor substrate includes an active pixel region and an optical black region. An annealing layer may be formed on the active pixel region and the optical black region and etched so that the annealing layer covers at least a portion of the optical black region. A wiring pattern may be formed on the annealing layer. A light-blocking pattern may be formed on the wiring pattern so as to cover the entire photoelectric conversion unit of the optical black region, thereby blocking light from being incident upon the optical black region.

摘要: An image sensor includes first pixels in an active region and second pixels in an optical black region of a pixel array. The first pixels have a gate that receives an active transfer control signal, and the second pixels have a gate that receives a passive transfer control signal, like a ground voltage.

摘要: An image sensor includes a pixel array and a calibration circuit. The pixel array includes a plurality of pixels each of which includes a photoelectric conversion device configured to absorb incident light and generate a photocharge, a transfer transistor configured to transfer the photocharge from the photoelectric conversion device to a floating diffusion node, and a reset transistor configured to reset the floating diffusion node. The calibration circuit is connected to the reset transistor of each pixel, and is configured to apply a different voltage to each pixel and adjust an amount of photocharge generated by the photoelectric conversion device in each pixel.
