Thermal ink jet resistor passivation |
摘要 |
A passivation layer for a thermal ink jet printhead is provided. The material of the passivation layer can be a Co-based alloy with 25-30 wt % Cr or an Fe-based alloy with <=10 wt. % Co, <=20 wt. % Cr, <=10 wt. % Mn. The passivation layer is amorphous and the surface is substantially atomically smooth or has a controlled surface roughness. The passivation layer displays resistance to cavitation and chemical corrosion and is conformally disposed over a resistor by sputtering or other physical vapor deposition techniques.
