Title (EN) FILTER DEVICE AND METHOD FOR PRODUCING FILTER DEVICE
(FR) DISPOSITIF DE FILTRE ET PROCÉDÉ DE PRODUCTION DE DISPOSITIF DE FILTRE
(JA) フィルタ装置およびフィルタ装置の製造方法
Abstract:
(EN) This filter device (1) is provided with: a substrate (50) which has piezoelectricity; a first filter (10) which comprises an IDT electrode (52) that is provided on the substrate (50); an electrode (30a) for terminals, which is provided on the substrate (50); a first wiring electrode (41) which is provided on the substrate (50) and connects the first filter (10) and the electrode (30a) for terminals with each other; and a dielectric film (61) which is provided on the substrate (50) so as to cover the IDT electrode (52). At least a part of the first wiring electrode (41) is not covered by the dielectric film (61).
(FR) Ce dispositif de filtre (1) comprend : un substrat (50) qui présente une piézoélectricité ; un premier filtre (10) qui comprend une électrode IDT (52) qui est disposée sur le substrat (50) ; une électrode (30a) pour des bornes, qui est disposée sur le substrat (50) ; une première électrode de câblage (41) qui est disposée sur le substrat (50) et connecte le premier filtre (10) et l'électrode (30a) pour des bornes l'un à l'autre ; et un film diélectrique (61) qui est disposé sur le substrat (50) de manière à recouvrir l'électrode IDT (52). Au moins une partie de la première électrode de câblage (41) n'est pas recouverte par le film diélectrique (61).
(JA) フィルタ装置(1)は、圧電性を有する基板(50)と、基板(50)上に設けられたIDT電極(52)を含む第1フィルタ(10)と、基板(50)上に設けられた端子用電極(30a)と、基板(50)上に設けられ、第1フィルタ(10)と端子用電極(30a)とをつなぐ第1の配線電極(41)と、IDT電極(52)を覆うように基板(50)上に設けられた誘電体膜(61)とを備える。第1の配線電極(41)の少なくとも一部は、誘電体膜(61)に覆われていない。
