Title (EN) SURFACE ACOUSTIC WAVE DEVICES CONTAINING ISOLATED INTERDIGITATED ELECTRODES
(FR) DISPOSITIFS A ONDES ACOUSTIQUES (SAW) DE SURFACE CONTENANT DES ELECTRODES INTERDIGITEES ISOLEES
Abstract:
(EN) A multilayer SAW device includes a wave propagation layer, at least one interdigitated electrode and a piezoelectric layer. The piezoelectric layer is configured to substantially isolate elements of the interdigitated electrode or electrodes. The various SAW devices provide discrete regions of the piezoelectric material adjacent to the interdigitated electrodes above the piezoelectric layer.
(FR) La présente invention concerne un dispositif multicouche SAW comprenant une couche de propagation d'onde, au moins une électrode interdigitée et une couche piézo-électrique. La couche piézo-électrique est configurée de façon à isoler sensiblement des éléments de l'électrode ou des électrodes interdigitées. Les divers dispositifs SAW fournissent des régions discrètes du matériau piézo-électrique adjacentes aux électrodes interdigitées au-dessus de la couche piézo-électrique.
