A method for forming a fluid injection apparatus is disclosed. A patterned sacrificial layer is formed overlying a substrate. A electroplate seed layer is formed on the patterned sacrificial layer. A structural layer is formed overlying the electroplate seed layer and the substrate. The structural layer is patterned to form a nozzle. The electroplate seed layer in the nozzle is removed. The sacrificial layer is removed to form a fluid chamber. A protective layer is formed to selectively cover the structural layer and the electroplate seed layer.
