Abstract:
1. A solid-state image device comprising: a photoelectric conversion portion which obtains a signal charge by photoelectric conversion of incident light; a pixel transistor portion which outputs a signal charge generated by the photoelectric conversion portion; a peripheral circuit portion which is provided at the periphery of a pixel portion including the photoelectric conversion portion and the pixel transistor portion and which has an NMOS transistor and a PMOS transistor; a first stress liner film which has a compressive stress and which is provided on the PMOS transistor; and a second stress liner film which has a tensile stress and which is provided on the NMOS transistor, wherein the photoelectric conversion portion, the pixel transistor portion, and the peripheral circuit portion are provided in and/or on a semiconductor substrate, the first stress liner film is provided on the photoelectric conversion portion and the pixel transistor portion as well as on the PMOS transistor, and the second stress liner film is provided on the pixel transistor portion as well as on the NMOS transistor.
