摘要： A method of forming a fluid ejector includes forming a recess well into a silicon wafer on a first side of the silicon wafer, and filling the recess well with a sacrificial material. A thin layer structure is deposited onto the first side of a silicon wafer covering the filled recess well. Then a thin film piezoelectric is bonded or deposited to the thin layer structure, and a hole is formed in the thin layer structure exposing at least a portion of the sacrificial material. The sacrificial material is removed from the recess well, wherein the hole in the thin layer in the recess well with the sacrificial material removed, form a fluid inlet. An opening area in the silicon wafer is formed on a second side of the silicon wafer. Then a nozzle plate is formed having a recess portion and an aperture within the recess portion. The nozzle plate is attached to the second side of the silicon wafer, with the recess portion positioned within the open area. The thin layer structure and the recess portion of the nozzle plate define a depth of a fluid cavity defined by the thin layer structure, the recess portion of the nozzle plate and the sidewalls of the silicon wafer.
