There is provided a CMOS image sensor and an electronic product using the same. The CMOS image sensor includes a plurality of pixels for embodying colors having different wavelengths. Each of pixels includes a buried barrier layer disposed in a semiconductor substrate and having a barrier potential energy of a conduction band thereof at an equilibrium state, a first layer disposed at a main surface of the semiconductor substrate separated from the buried barrier layer in a vertical direction and having a first potential energy of a conduction band thereof at the equilibrium state, and a second layer disposed between the first region and the buried barrier layer having a second potential energy of a conduction band thereof at the equilibrium state. The second potential energy is higher than the first potential energy and the barrier potential energy and a thickness of the second layer is thicker as the wavelength is longer
