SOLID-STATE IMAGING ELEMENT
Document Type and Number:
Japanese Patent JP2021166304
Kind Code:
A
Abstract:
To enable more reliable separation between pixels.SOLUTION: A solid-state imaging element includes a photoelectric conversion unit, a first separation unit, and a second separation unit. The photoelectric conversion unit photoelectrically converts incident light, and the first separation unit that separates the photoelectric conversion unit is formed in a first trench formed from the first surface side, and the second separation unit that separates the photoelectric conversion unit is formed in a second trench formed from the second surface side facing the first surface. This technology can be applied to an individual imaging element that is mounted on a camera or the like and captures a subject.SELECTED DRAWING: Figure 2
