A fluid ejector head, includes a fluid definition layer defining a chamber, the fluid definition layer having a substantially planar passivation surface. In addition, the fluid ejector head includes a sacrificial material filling the chamber that is planarized to the plane formed by the passivation surface. Further, the fluid ejector head includes a passivation layer, having substantially planar opposed major surfaces, formed on the planar passivation surface; and a resistive layer having substantially planar opposed major surfaces in contact with the passivation layer.
