Title (EN) MONOLITHIC PRINTHEAD AND ASSOCIATED MANUFACTURING PROCESS
(FR) TETE D'IMPRESSION MONOLITHIQUE ET PROCEDE DE FABRICATION ASSOCIE
Abstract:
(EN) An actuating assembly (81) for ink jet printheads consists of a silicon die (161) and a structure (175), made monolithically in the same manufacturing process; the die (161) comprises microelectronics (162) and microhydraulics (163), in turn made of a lamina (164), a groove (145) and a plurality of channels (167); the structure (175) contains a plurality of chambers (157) and nozzles (156). The actuating assembly (81) is made via the operations of producing the microelectronics (162), cutting the groove (145), drilling the channels (167), growing a sacrificial metallic layer (154) and the structure (175), drilling the nozzles (156) and taking away the sacrificial layer (154).
(FR) L'invention concerne un ensemble actionneur (81) pour têtes d'impression à jet d'encre, cet ensemble étant constitué d'une puce en silicium (161) et d'une structure (175), fabriquées de manière monolithique selon le même procédé de production. La puce (161) présente des circuits microélectroniques (162) et des dispositifs microhydrauliques (163), eux-mêmes composés d'une lame (164), d'une rainure (145) et d'une pluralité de canaux (167). La structure susmentionnée (175) contient une pluralité de chambres (157) et de buses (156), l'ensemble actionneur (81) de cette invention étant fabriqué au cours des opérations de production desdits circuits microélectroniques (162) qui consistent notamment à ménager la rainure (145), à creuser les canaux (167), à faire croître une couche métallique sacrificielle (154), à constituer ladite structure (175), à percer les buses (156) et enfin à retirer la couche sacrificielle (154).
