Abstract
Electrical signals delivered by detectors at the surface of a first high-capacitance insulating layer which provides a separation between a first array of metallic electrodes and the detectors are collected by the electrodes by capacitive coupling. The first array of electrodes is electrically connected to a second array of electrodes having smaller dimensions. The two arrays are separated by a second insulating layer and the second array is located at the interface between the second insulating layer and the oxide layer which covers the semiconductor readout substrate.
