Abstract:
A method of manufacturing a fluid jetting apparatus comprising:forming an electrode and an exothermic body on a substrate; laminating a plane layer on the substrate at a same height as the electrode and the exothermic body combined; laminating a protective layer on the electrode and the plane layer; laminating a working fluid barrier on the protective layer, and forming a working fluid chamber in the working fluid barrier; forming a sacrificial layer on the protective layer and within an interior of the working fluid chamber at a same height as the working fluid barrier; laminating a membrane on the working fluid barrier and the sacrificial layer formed to the same height as the working fluid barrier; laminating a jetting fluid barrier on the membrane, and forming a jetting fluid chamber in the jetting fluid barrier; laminating a nozzle plate on the jetting fluid barrier, and forming a nozzle in the nozzle plate; and removing the sacrificial layer.
