Abstract

An image sensing device is provided to include a pixel region and a peripheral region located outside of the pixel region. The peripheral region includes logic circuits located to receive a 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, a recessed structure, and a first junction. The active region includes a first impurity region and a second impurity region formed over the first impurity region. The recessed structure is at least partly disposed in the active region and including a first portion disposed in the active region and including a conductive material and a second portion surrounding the first portion and including an insulation material. The first junction is formed in the active region and spaced apart from the recessed structure by a predetermined distance.
