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.
