Abstract
A method for fabricating a fluid nozzle array includes forming a circuitry layer onto a substrate, the substrate comprising a stopping layer disposed between a membrane layer and a handle layer, forming a fluid feedhole extending from a surface of the membrane layer to the stopping layer, and forming a fluid supply trench extending from a surface of the handle layer to the stopping layer. A fluid nozzle array includes a substrate including a membrane layer, a stopping layer adjacent to the membrane layer, a handle layer adjacent to the stopping layer, and a set of fluid chambers disposed on a surface of the membrane layer above and along a width of a fluid supply trench extending from a surface of the handle layer to the stopping layer.
