ABSTRACT:
A nozzle array structure for pressurized fluid jets includes a uniform deposited membrane having an array of uniform small orifices therein overlaying a planar substrate having an array of larger aperture openings therethrough with approximately the same central axes as the orifice array. The method of making includes forming a substrate of a planar single crystal material oriented with the (100) planes parallel to the surface. A membrane comprising a uniform coating of an inorganic material is applied to the planar surface of the substrate. The substrate is preferentially etched from the rear surface to form an array of openings therein extending therethrough to the membrane. The membrane is then selectively eroded to form an array of uniform small orifices therein.
