Abstract

A photodetector array made in monolithic form, in which transistors are formed in a semiconductor substrate coated with several metallization levels and photodiodes are formed above a last metallization level, each photodiode having an upper region of a first conductivity type common to all photodiodes and an individual lower region forming a junction with the upper region in contact with a metallization of the last level, wherein each lower region is separated from the neighboring lower regions by an insulating material and is connected to the metallization through a via formed in at least one insulating layer.
