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.

An image sensor includes a substrate, an anti-reflection board and a light shielding film. The substrate includes first pixels to receive a light, and second pixels to provide a black level compensation. The first pixels are formed in an active region and the second pixels are formed in a first region spaced apart from the active region in a row direction. The anti-reflection board is formed in a second region above the substrate, and the second region is between the active region and the first region. The light shielding film is formed above the anti-reflection board, and the light shielding film covers an optical black region including the first and second regions. Therefore, the image sensor may be used in a CCD type image sensor and a CMOS type image sensor to provide a stabilized black level, thereby improving a quality of a displayed image.

A CMOS image sensor includes a photosensitive device, a floating diffusion region, a transfer transistor, and a pocket photodiode formed in a semiconductor substrate of a first conductivity type. The floating diffusion region is of a second conductivity type. The transfer transistor has a channel region disposed between the photosensitive device and the floating diffusion region. The pocket photodiode is of the second conductivity type and is formed under a first portion of a bottom surface of the channel region such that a second portion of the bottom surface of the channel region abuts the semiconductor substrate.

A refrigerator including a cooling chamber in a main body, includes: a rack assembly installed inside the cooling chamber; and a rack assembly drawing unit for drawing/putting the rack assembly out of/into the cooling chamber. Accordingly, food containers put on a rack of a rack assembly can be easily and conveniently taken out or checked regardless their locations by constructing the rack assembly to be selectively drawn out of a cooling chamber. Also, by attaching a vibration preventing rubber material to an end of the rack assembly, the food container put on the rack is prevented from being dropped, and the vibration noise can be effectively prevented.
