Abstract
A method of making inkjet print heads may include forming a first wafer including a sacrificial substrate layer, and a first dielectric layer thereon having first openings therein defining inkjet orifices. The method may also include forming a second wafer having inkjet chambers defined thereon, and joining the first and second wafers together so that each inkjet orifice is aligned with a respective inkjet chamber. The method may further include removing the sacrificial substrate layer thereby defining the inkjet print heads.
