IMAGING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18442157 titled 'IMAGING DEVICE
The abstract of the patent application describes an imaging device that includes a semiconductor substrate, effective and non-effective pixel regions, a photoelectric converter, a light-shielding film containing titanium or tantalum, and a functional film with a thickness less than the light-shielding film.
- The imaging device comprises a semiconductor substrate.
- It has an effective pixel region with an effective pixel and a non-effective pixel region surrounding it.
- A photoelectric converter is located above the semiconductor substrate, with portions in both the effective and non-effective pixel regions.
- A light-shielding film containing titanium or tantalum is positioned above the second portion of the photoelectric converter.
- A functional film, thinner than the light-shielding film, is in contact with the light-shielding film.
Potential Applications: - This technology can be used in digital cameras, smartphones, and other imaging devices. - It may find applications in medical imaging equipment and surveillance systems.
Problems Solved: - Reducing noise and improving image quality in imaging devices. - Enhancing the performance of photoelectric converters in capturing light.
Benefits: - Improved image quality and sensitivity. - Reduction in noise and interference. - Enhanced performance in low-light conditions.
Commercial Applications: Title: "Advanced Imaging Technology for Enhanced Image Quality" This technology can be utilized in the development of high-end digital cameras, medical imaging devices, and surveillance systems, catering to professionals and enthusiasts who require superior image quality and performance.
Questions about the technology: 1. How does the use of titanium or tantalum in the light-shielding film contribute to the performance of the imaging device? 2. What are the potential cost implications of implementing this technology in commercial imaging devices?
Original Abstract Submitted
An imaging device includes: a semiconductor substrate; an effective pixel region including an effective pixel; a non-effective pixel region that is located around the effective pixel region and that does not include the effective pixel; a photoelectric converter that is located above the semiconductor substrate and that includes a first portion located in the effective pixel region and a second portion located in the non-effective pixel region; a light-shielding film that is located above the second portion of the photoelectric converter and that contains titanium or tantalum; and a functional film that is located on the light-shielding film and that is in contact with the light-shielding film. The functional film has a thickness less than a thickness of the light-shielding film.
