NEAR INFRARED/COLOR IMAGE SENSOR
First Claim
1. A near infrared/color photodetector made in a monolithic form in a lightly-doped substrate of a first conductivity type covering a holder and comprising a face on the side opposed to the holder, the photodetector comprising:
- at least first and second photodiodes for the storage of electric charges photogenerated in the substrate, the second photodiode being adjacent to said face; and
a first region located at least between the second photodiode and the holder, preventing the passage of said charges between a first substrate portion extending between said region and the holder and a second substrate portion extending between said face and the first region, the first photodiode being adapted to store at least charges photogenerated in the first substrate portion and the second photodiode being adapted to store charges photogenerated in the second substrate portion.

Abstract
A near infrared/color photodetector made in a monolithic form in a lightly-doped substrate of a first conductivity type covering a holder and comprising a face on the side opposed to the holder. The photodetector includes at least first and second photodiodes for the storage of electric charges photogenerated in the substrate, the second photodiode being adjacent to said face; and a first region extending at least between the second photodiode and the holder, preventing the passage of said charges between a first substrate portion being located between said region and the holder and a second substrate portion extending between said face and the first region, the first photodiode being adapted to store at least charges photogenerated in the first substrate portion and the second photodiode being adapted to store charges photogenerated in the second substrate portion.
