SOLID STATE IMAGE SENSOR, PRODUCTION METHOD THEREOF AND ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240349526 titled 'SOLID STATE IMAGE SENSOR, PRODUCTION METHOD THEREOF AND ELECTRONIC DEVICE
The abstract describes a solid-state image sensor with photoelectric conversion regions arranged per pixel on a semiconductor substrate, an organic photoelectric conversion film laminated on the light-irradiated side of the substrate, lower and first upper electrodes, and a film stress suppressor.
- Photoelectric conversion regions for converting light into charges are arranged per pixel on a semiconductor substrate.
- An organic photoelectric conversion film is laminated on the light-irradiated side of the substrate via an insulation film.
- Lower electrode is formed in contact with the organic photoelectric conversion film on the semiconductor substrate side.
- First upper electrode is laminated on the light-irradiated side of the organic photoelectric conversion film, conforming with its ends.
- Film stress suppressor is included to counteract the effect of film stress on the organic photoelectric conversion film.
Potential Applications: - Digital cameras - Medical imaging devices - Surveillance systems
Problems Solved: - Improved image quality - Enhanced sensitivity to light - Reduction of film stress effects
Benefits: - Higher quality images - Increased performance in low-light conditions - Longer lifespan of the image sensor
Commercial Applications: Title: Advanced Image Sensors for High-Performance Cameras This technology can be used in high-end digital cameras, medical imaging equipment, and surveillance systems, enhancing image quality and sensitivity to light. The market implications include improved performance in various industries relying on high-quality imaging.
Questions about Solid-State Image Sensors: 1. How does the organic photoelectric conversion film improve image quality in the sensor? The organic photoelectric conversion film enhances the sensor's sensitivity to light, resulting in clearer and more detailed images.
2. What role does the film stress suppressor play in the functionality of the image sensor? The film stress suppressor helps to counteract the negative effects of film stress on the organic photoelectric conversion film, ensuring its longevity and performance.
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.
