Abstract
A method for manufacturing a fluid ejection device includes providing a sacrificial structure substantially overlying a semiconductor substrate. The structure has a shape configured to define an ink chamber, ink manifold, and a nozzle. The method also includes providing a first metal adjacent the sacrificial structure and substantially overlying the substrate and removing the sacrificial structure to form the ink chamber and the nozzle. The method further includes removing a portion of the first and second sacrificial materials to form the sacrificial structure.
