Abstract: A method of making inkjet print heads may include forming recesses in a first surface of a first wafer to define inkjet chambers. The method may also include forming openings extending from a second surface of the first wafer through to respective ones of the inkjet chambers to define inkjet orifices. The method may further include forming a second wafer including ink heaters, and joining the first and second wafers together so that the ink heaters are aligned within respective inkjet chambers to thereby define the inkjet print heads.

Abstract: A method of making an inkjet print head may include forming, by sawing with a rotary saw blade, first discontinuous slotted recesses in a first surface of a wafer. The first discontinuous slotted recesses may be arranged in parallel, spaced apart relation. The method may further include forming, by sawing with the rotary saw blade, second discontinuous slotted recesses in a second surface of the wafer aligned and coupled in communication with the first continuous slotted recesses to define through-wafer channels. In another embodiment, the first and second plurality of discontinuous recesses may be formed by respective first and second rotary saw blades.
