Abstract (en)
[origin: EP0930166A2] A manufacturing process and a structure for an ink jet printhead with high quality, yield rate, and performance are provided. The process includes steps of: a) providing a substrate, b) forming a dielectric layer over the substrate, c) forming a resistor over the dielectric layer, d) forming a conducting layer over a portion of the resistor, e) forming a passivation over a portion of the conducting layer and another portion of the resistor not covered by the conducting layer, f) forming a hole over the passivation for storing an ink, and g) forming a nozzle over the hole for ejecting therethrough the ink. <IMAGE>
