    摘要: A transistor having an electrode layer that can reduce or prevent a coupling effect, a fabricating method thereof, and an image sensor having the same are provided. The transistor includes a semiconductor substrate and a well of a first conductivity type formed on the semiconductor substrate. A heavily-doped first impurity region of a first conductivity type surrounds an active region defined in the well. Heavily-doped second and third impurity regions of a second conductivity type are spaced apart from each other in the active region an define a channel region interposed therebetween. A gate is formed over the channel region to cross the active region. The gate overlaps at least a portion of the first impurity region and receives a first voltage. An electrode layer is formed between the semiconductor substrate and the gate, such that the electrode layer overlaps a portion of the first impurity region contacting the channel region and receives a second voltage. An insulation layer is formed between the semiconductor substrate and the electrode layer, the semiconductor substrate and the gate, and the electrode layer and the gate. The insulation layer surrounds the electrode layer.

    摘要: A charge-coupled device (CCD) is provides having improved charge transfer efficiency. This CCD is a portion of an image sensor and manufactured by first laminating a first oxidation film and a first nitride film one after the other on a semiconductor substrate and then forming a plurality of first gate electrodes on the first nitride film at predetermined intervals apart. A second oxidation film is formed only on an upper surface and along side walls of each of the first gate electrodes. The first nitride film exposed between the first gate electrodes is removed and a second nitride film is formed on the exposed first oxidation film and the second oxidation film. A second gate electrode is then formed on the second nitride film between adjacent first gate electrodes. An image sensor is obtained in which leakage current density between the gate electrodes is reduced and the dielectric characteristic of a gate dielectric film is improved.
