Title:
SOLID-STATE IMAGING ELEMENT AND ELECTRONIC DEVICE
Document Type and Number:
Japanese Patent JP2021141264
Kind Code:
A
Abstract:
To provide an optical spectrum with high spectral accuracy in a solid-state imaging element.SOLUTION: A solid-state imaging element includes a semiconductor substrate and a filter. A photodiode is formed on the semiconductor substrate. The filter is included in a multilayer structure laminated on a light receiving surface side of the semiconductor substrate. In the filter, a periodic pattern array is rotated in accordance with an incident direction of a main ray. For example, a propagation type surface plasmon resonance filter or a localized surface plasmon resonance filter is used as the filter.SELECTED DRAWING: Figure 1
