Abstract

Selon un mode de réalisation, un condensateur inclut un substrat conducteur, une couche conductrice, une couche diélectrique, et des première et seconde électrodes externes. Le substrat conducteur comporte une première surface principale, une seconde surface principale, et une face d’extrémité s’étendant depuis un bord de la première surface principale vers un bord de la seconde surface principale, la première surface principale étant pourvue d’un ou de plusieurs évidements. La couche conductrice couvre la première surface principale et des parois latérales et des surfaces de dessous des un ou plusieurs évidements. La couche diélectrique est interposée entre le substrat conducteur et la couche conductrice. La première électrode externe inclut une première portion d’électrode en regard de la face d’extrémité et est connectée électriquement à la couche conductrice. La seconde électrode externe inclut une seconde portion d’électrode en regard de la face d’extrémité et est connectée électriquement au substrat conducteur.
