Abstract
An image sensing device is provided to include a pixel region including image pixels and a peripheral region located outside of the pixel region. The peripheral region includes logic circuits located to receive the pixel signals from the pixel region and configured to process the pixel signals, and a capacitor located adjacent to the logic circuits. The capacitor includes an active region including a first impurity region and a second impurity region formed over the first impurity region, a recessed structure including a portion formed in the active region, the portion including a conductive layer extending along a direction that the first impurity region and the second impurity region are stacked and an insulation layer formed between the conductive layer and the active region, and a first junction formed in the active region and spaced apart from the recessed structure by a predetermined distance.
