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.

A fluid ejection device, a method of cleaning the device, and a method of operating the device are provided. The device includes a substrate having a first surface and a second surface located opposite the first surface. A nozzle plate is formed over the first surface of the substrate and has a nozzle through which fluid is ejected. A drop forming mechanism is situated at the periphery of the nozzle. A fluid chamber is in fluid communication with the nozzle and has a first wall and a second wall. The first wall and the second wall are positioned at an angle other than 90° relative to each other. A fluid delivery channel is formed in the substrate and extends from the second surface of the substrate to the fluid chamber. The fluid delivery channel is in fluid communication with the fluid chamber.

A method of etching a substrate and an article(s) formed using the method are provided. The method includes providing a substrate; coating a region of the substrate with a temporary material having properties that enable the temporary material to remain substantially intact during subsequent processing and enable the temporary material to be removed by a subsequent process that allows the substrate to remain substantially unaltered; removing a portion of the substrate to form a feature, at least some of the removed portion of the substrate overlapping at least a portion of the coated region of the substrate while allowing the temporary material substantially intact; and removing the temporary material while allowing the substrate to remain substantially unaltered.
