Abstract
An image sensor is provided. The image sensor comprises a semiconductor substrate, a dielectric interlayer, an interconnection, an image sensing unit, a via hole piercing the image sensing unit and the dielectric layer, and a bottom electrode. The semiconductor substrate includes a readout circuit. The dielectric interlayer is disposed on the semiconductor substrate. The interconnection is disposed in the dielectric interlayer and connected electrically to the readout circuit. The image sensing unit is disposed on the dielectric interlayer and includes a stack of a first impurity region and a second impurity region. The via hole pierces the image sensing unit and the dielectric interlayer to expose the interconnection. The bottom electrode is disposed in the via hole to electrically connect the interconnection and the first impurity region of the image sensing unit.
