摘要: A printhead for an inkjet or like printing apparatus having a passivation layer of varied thickness. The is relatively thin over the ink expulsion element to reduce energy required expel ink. thick other regions substrate, particularly those in which circuitry provided. increased thickness protects against capacitive coupling and like. Methods forming are also disclosed.
