Abstract

The invention relates to a photodetectors array that will be hybridized on a readout circuit (30) and realized from a wafer of semiconducting material (11). The wafer is divided into pixels (12), each pixel forming a photodetector, the pixels being separated from each other by separation means formed in the wafer and comprising a photogrid for photodetectors, each photodetector having a connection pad (18) to hybridize the photodetectors array to the readout circuit.
