Title
(DE) ENTFERNUNG EINES GENEIGTEN SEGMENTS EINES METALLLEITERS BEI DER HERSTELLUNG VON DRUCKKÖPFEN
(EN) REMOVING AN INCLINED SEGMENT OF A METAL CONDUCTOR WHILE FORMING PRINTHEADS
(FR) ÉLIMINATION D'UN SEGMENT INCLINÉ D'UN CONDUCTEUR MÉTALLIQUE TOUT EN FORMANT DES TÊTES D'IMPRESSION
Abstract
(EN) An example of a method of forming a printhead includes forming first and second resistors over a first dielectric, forming a first portion of a second dielectric over the first and second resistors and a second portion of the second dielectric over an exposed inclined surface of the first dielectric in a region between the first and second resistors, forming a metal conductor over the first and second portions of the second dielectric, and removing an inclined segment of the metal conductor from an inclined surface of the second portion of the second dielectric to expose the inclined surface of the second portion of the second dielectric.
(FR) La présente invention concerne un exemple d'un procédé de formation d'une tête d'impression qui consiste à former des première et seconde résistances sur un premier diélectrique, à former une première partie d'un second diélectrique sur les première et seconde résistances et une seconde partie du second diélectrique sur une surface inclinée exposée du premier diélectrique dans une région entre les première et seconde résistances, à former un conducteur métallique sur les première et seconde parties du second diélectrique, et à enlever un segment incliné du conducteur métallique d'une surface inclinée de la seconde partie du second diélectrique pour exposer la surface inclinée de la seconde partie du second diélectrique.
