    摘要： A method of forming a fluid chamber and a source of fluid impedance includes providing a substrate having a surface; depositing a first material layer on the surface of the substrate, the first material layer being differentially etchable with respect to the substrate; removing a portion of the first material layer thereby forming a patterned first material layer and defining the fluid chamber boundary location; depositing a sacrificial material layer over the patterned first layer; removing a portion of the sacrificial material layer thereby forming a patterned sacrificial material layer and further defining the fluid chamber boundary location; depositing at least one additional material layer over the patterned sacrificial material layer; forming a hole extending from the at least one additional material layer to the sacrificial material layer, the hole being positioned within the fluid chamber boundary location; removing the sacrificial material layer in the fluid chamber boundary location by introducing an etchant through the hole; forming the fluid chamber by introducing an etchant through the hole; and forming a source of fluid impedance.

The first surface includes a nozzle orifice. A drop forming mechanism is located on the second surface of the chamber opposite the nozzle orifice. A first liquid feed channel and a second liquid feed channel are in fluid communication with the chamber. A first segment of a segmented liquid inlet is in fluid communication with the first liquid feed channel and a second segment of the segmented liquid inlet is in fluid communication with the second liquid feed channel. The first segment of the segmented liquid inlet is also in fluid communication with another one of the plurality of chambers and the second segment of the liquid inlet is also in fluid communication with another one of the plurality of chambers. A liquid is provided to the chamber through the first liquid feed channel and the second liquid feed channel from the segmented liquid inlet. A drop of the liquid is ejected through the nozzle orifice of the chamber by operating the associated drop forming mechanism.
