Title (EN) FLUID EJECTION DEVICE WITH INK FEEDHOLE BRIDGE
(FR) DISPOSITIF D'ÉJECTION DE FLUIDE DOTÉ D'UN PONT DE TROU D'ALIMENTATION EN ENCRE
Abstract: front page image
(EN)In an embodiment, a fluid ejection device includes a substrate with a fluid slot formed therein, a chamber layer formed on the substrate defining fluid chambers on both sides of the fluid slot, a thin-film layer between the substrate and chamber layer that defines an ink feedhole (IFH) between the fluid slot and the chamber layer, and a chamber layer extension that forms a bridge across the IFH between two chambers.
(FR)Selon un mode de réalisation, la présente invention concerne un dispositif d'éjection de fluide qui comprend un substrat doté d'une fente de fluide formée en son sein, une couche de chambre formée sur le substrat délimitant des chambres de fluide de chaque côté de la fente de fluide, une couche de film mince entre le substrat et la couche de chambre qui définit un trou (IFH) d'alimentation en encre entre la fente de fluide et la couche de chambre et une extension de couche de chambre qui forme un pont en travers de l'IFH entre deux chambres.
