    Abstract: A method for fabricating a fluid nozzle array includes forming a circuitry layer (410) onto a substrate (412), the substrate (412) comprising a stopping layer (404) disposed between a membrane layer (406) and a handle layer (402), forming a fluid feedhole (502) extending from a surface of the membrane layer (406) to the stopping layer (404), and forming a fluid supply trench (702) extending from a surface of the handle layer (402) to the stopping layer (404). A fluid nozzle array includes a substrate (412) including a membrane layer (406), a stopping layer (404) adjacent to the membrane layer, a handle layer (406) adjacent to the stopping layer, and a set of fluid chambers (610) disposed on a surface of the membrane layer above and along a width of a fluid supply trench (702) extending from a surface of the handle layer to the stopping layer.

    Abstract: A fluid recirculation channel for dispensing a plurality of fluid drop weights includes a number of sub-channels. The sub-channels include at least one pump channel, and a plurality of drop generator channels fluidically coupled to the at least one pump channel. The fluid recirculation channel further includes a number of pump generators incorporated into the at least one pump channel, a number of drop generators incorporated into drop generator channels, and a plurality of nozzles defined within the drop generator channels, the nozzles being at least as numerous as the number of drop generators.
