Abstract
Methods of manufacturing a fluid ejection device comprise, in one embodiment, forming filler structures on a substrate and laminating a dry film onto the substrate over the filler structures. The dry film defines a barrier layer around the filler structures and an orifice layer above the filler structures. The filler structures are removed to form voids within the barrier layer.
