Abstract
Tête de lecture pour impression thermique. Sur un substrat 11, recouvert de glaçure, on dépose successivement une couche de nitrure de tantale 12, d'une couche d'oxy-nitrure servant de barrière, d'une couche d'or 13, puis d'une autre couche de nitrure de tantale 20. On décape de façon sélective les couches 13 et 20 afin de former les configurations de résistances choisies. Ensuite, on dépose une couche de dioxyde de silicium 22, puis d'oxyde de tantale 24. Tête utilisable dans les imprimantes utilisant un procédé d'impression thermique.
