The flow feature layer is disposed over the substrate, and the flow feature layer include one or more flow features each in communication with at least one of the one or more fluid ports. The nozzle layer is disposed over the flow feature layer, and the nozzle layer includes one or more nozzles each in communication with at least one of the one or more flow features so that one or more fluid paths are defined by the one or more fluid channels, the one or more fluid ports, the one or more flow features, and the one or more nozzles. The one or more valves selectively impede flow of fluid through the one or more fluid paths.
