SOLID STATE IMAGE SENSOR, PRODUCTION METHOD THEREOF AND ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18755096 titled 'SOLID STATE IMAGE SENSOR, PRODUCTION METHOD THEREOF AND ELECTRONIC DEVICE
Simplified Explanation: The patent application describes a solid-state image sensor with organic photoelectric conversion film to convert light into charges, lower and upper electrodes, and a film stress suppressor to reduce the impact of film stress on the organic film.
- Photoelectric conversion regions on a semiconductor substrate convert light into charges per pixel.
- An organic photoelectric conversion film is layered on the light-exposed side of the substrate via an insulation film.
- A lower electrode is in contact with the organic film on the semiconductor side.
- A first upper electrode is placed on the light-exposed side of the organic film, aligning with its ends.
- A film stress suppressor minimizes the effect of film stress on the organic film.

Original Abstract Submitted
A solid state image sensor includes a semiconductor substrate where photoelectric conversion regions for converting light into charges are arranged per pixel planarly arranged; an organic photoelectric conversion film laminated at a light irradiated side of the semiconductor substrate via an insulation film and formed at the regions where the pixels are formed; a lower electrode formed at and in contact with the organic photoelectric conversion film at a semiconductor substrate side; a first upper electrode laminated at a light irradiated side of the organic photoelectric conversion film and formed such that ends of the first upper electrode are substantially conform with ends of the organic photoelectric conversion film when the solid state image sensor is planarly viewed; and a film stress suppressor for suppressing an effect of a film stress on the organic photoelectric conversion film, the film stress being generated on the first upper electrode.
