Abstract: The invention relates to the manufacture of a matrix sensor using a sensitive layer of a ferroelectric P(VDF/TrFE) copolymer, deposited on an integrated circuit. In order to simplify the manufacture and improve the yields, deposited first on the integrated circuit is a first layer of titanium and it is etched in order to form a matrix array of electrodes electrically connected to the integrated circuit; next, a P(VDF/TrFE) copolymer comprising a small proportion of around 1 to 10% of a second polymer that favors the adhesion of the P(VDF/TrFE) copolymer is deposited on the integrated circuit; the polymer is either underneath the P(VDF/TrFE) or blended therewith. The copolymer and its adhesion promoter are etched in a single step, and finally a second conductive layer is deposited and it is etched in order to form a counter electrode for the whole of the matrix array. For use in ultrasonic image sensors.
