  • Publication number: 20060273363
    Abstract: A method for fabricating a CMOS image sensor is provided. The method includes: forming a gate electrode with a gate insulating layer interposed on a transistor region of a semiconductor substrate having an active region defined by a photo diode and a transistor region; forming a first impurity region of a first conductive type at a transistor region at one side of the gate electrode; forming a second impurity region of a first conductive type at a photo diode region at other side of the gate electrode; forming sidewall insulating layers at both sides of the gate electrode; forming a third impurity region of a first conductive type at one side of a gate electrode where the first impurity region is formed; and forming a fourth impurity region of a second conductive type at the gate electrode, the photodiode region and the transistor region by implanting impurity ions of a second conductive type on the entire surface of the semiconductor substrate.
