Fluid-jet printhead and method of fabricating a fluid-jet printhead

摘要

A fluid-jet printhead has a substrate on which at least one layer defining a fluid chamber for ejecting fluid is applied. The printhead includes an elevation layer disposed on the substrate and aligned with the fluid chamber. The printhead also includes a resistive layer disposed between the elevation layer and the substrate wherein the resistive layer has a smooth planer surface interfacing with the resistive layer.
