Sony patents light sensor with internal structures to improve detection
Sony has filed a patent for a light-detecting device that uses two electrodes with multiple small structures placed between them. A thin film that converts light into electricity sits between these structures and the second electrode to capture light signals.
In the filing’s own words
A light detecting device according to an embodiment of the present disclosure includes a first electrode, a second electrode provided opposed to the first electrode, multiple first structures each provided close to the first electrode between the first electrode and the second electrode, and a photoelectric conversion film provided between the multiple first structures and the second electrode.
What exactly they claim (claim 1)
1. A light detection device comprising: a first electrode; a second electrode provided opposed to the first electrode; multiple first structures each provided close to the first electrode between the first electrode and the second electrode; and a photoelectric conversion film provided between the multiple first structures and the second electrode.
