Abstract:
A process for the fabrication of an acoustic probe including an interconnection circuit and individual transducers produced in a plate of piezoelectric material, said process comprising:producing a plurality of conducting tracks on at least a first side of a dielectric film; bonding, after said producing of the plurality of conducting tracks, said first side of said dielectric film having said plurality of conducting tracks to a layer of piezoelectric material using a layer of dielectric adhesive; producing vias through a second side of said dielectric film, opposite to said first side, and said layer of dielectric adhesive by a localization process to simultaneously produce the vias emerging on at least one of said plurality of conducting tracks and on an associated metallization; and producing electrical contacts between said plurality of conducting tracks and the metallization of said associated piezoelectric material.
