  • Publication number: 20080048221
    Abstract: Embodiments relate to an image sensor and a method for manufacturing an image sensor. According to embodiments, ions of low concentration may be implanted into a photodiode region of a semiconductor substrate to form a photodiode. At least one gate insulating layer pattern may be formed on the semiconductor substrate, and a gate electrode may be formed on each of the at least one gate insulating layer pattern to receive charges from the photodiode. Spacers may be formed at sidewalls of the gate electrode, respectively. A selective epitaxial growth layer may be formed on the photodiode, and ions of low concentration may be obliquely implanted into one side and the other side of the gate electrode to form a low concentration source and a low concentration drain extending below the spacer. Subsequently, a high concentration source and a high concentration drain may be formed on both sides of the gate electrode, respectively.
