Canon new Three-Layer sensor patent surfaced over the web, the three layer sensor will increase the sensitivity & Overall performance of the camera take a look at the details below,
Description and self-interpretation of the patent literature / Translated by google
- Patent Publication No. 2013-93553
- Publication date 2013.5.16
- Filing date 2011.10.4
- Imaging element of three-layer structure
- Photodiode deep layer (hereinafter, PD) in the charge is diffused into the substrate
- Thus sensitivity is poor red
- Canon patent of
- I as a photonic crystal of irregular shape, the boundary surface of the PD of red or green,
- In the periodic structure of uneven spacing, less than twice the 1/4 times or more the wavelength of light, or I shall be two times or less 1/2 times or more
- Irregular shape has the properties to be spatially-localized or resonant light
- The incident light is diffracted, it combines with the light of the boundary plane, the resonant
- Prolonged exists than normal, the light becomes easy to be absorbed by the PD Thus
