Title
(EN) PIEZOELECTRIC INKJET DIE STACK
(FR) PILE DE MATRICES À JET D'ENCRE PIÉZOÉLECTRIQUES
Abstract
(EN)
A piezoelectric inkjet die stack includes a circuit die stacked on a substrate die, a piezoelectric actuator die stacked on the circuit die, and a cap die stacked on the piezoelectric actuator die. Each die in succession from the circuit die to the cap die is narrower than the previous die.
(FR)
Une pile de matrices à jet d'encre piézoélectriques comprend une matrice circuit empilée sur une matrice substrat, une matrice actionneur piézoélectrique empilée sur la matrice circuit, et une matrice chapeau empilée sur la matrice actionneur piézoélectrique. Chaque matrice de la série allant de la matrice circuit à la matrice chapeau est plus étroite que la matrice qui la précède.
