Abstract: front page image
(EN)A thermal inkjet printhead is described. The thermal inkjet printhead comprising a passivation layer and a plurality of bond pads formed over the passivation layer. The thermal inkjet printhead further comprises a plurality of insulating strips formed over the passivation layer. The insulating strips are formed such that two adjacent bond pads are separated by an insulating strip, from among the plurality of insulating strips. Further, each of the plurality of the insulating strips is of a dielectric material.
(FR)L'invention concerne une tête d'impression à jet d'encre thermique. La tête d'impression à jet d'encre thermique comprend une couche de passivation et une pluralité de plots de connexion formés sur la couche de passivation. La tête d'impression à jet d'encre thermique comprend en outre une pluralité de bandes isolantes formées sur la couche de passivation. Les bandes isolantes sont formées de telle sorte que deux plots de connexion adjacents sont séparés par une bande isolante de la pluralité de bandes isolantes.
