  • RADIATION SENSOR ELEMENT AND METHOD
    Publication number: 20230420585
    Abstract: This disclosure relates to a radiation sensor element comprising a semiconductor substrate, having a bulk refractive index; a front surface; a back surface, extending substantially along a base plane; and a plurality of pixel portions. Each pixel portion comprises a collection region on the back surface and a textured region on the front surface. The textured regions comprise high aspect ratio nanostructures, extending substantially along a thickness direction perpendicular to the base plane and forming an optical conversion layer, having an effective refractive index gradually changing towards the bulk refractive index to reduce reflection of light incident on said pixel portion from the front side of the semiconductor substrate.
    Type: Application
    Filed: September 7, 2023
    Publication date: December 28, 2023
    Applicant: ELFYS OY
    Inventors: Antti HAARAHILTUNEN, Juha HEINONEN, Mikko JUNTUNEN, Chiara MODANESE, Toni PASANEN, Hele SAVIN, Ville VÄHÄNISSI
