Abstract

L'invention concerne un procédé de fabrication d'un dispositif à interaction d'ondes acoustiques superficielles. Ce procédé consiste à former des électrodes imbriquées sur une surface plane d'une plaque piézo-électrique, à recouvrir cette électrode avec une mince couche de matière diélectrique et à appliquer une tension continue prédéterminée dans la direction de l'épaisseur de la plaque piézo-électrique pour la polariser. L'invention s'applique notamment à la fabrication de filtres à ondes acoustiques superficielles.
