Реферат: In an embodiment, a method of forming a printhead includes forming on a front-side surface of a substrate, a thin film layer and a plurality of fluidic channels and ejection chambers. The method also includes forming a slot through the substrate from the back-side surface to the front-side surface, where the back-side and front-side surfaces generally oppose one another. The slot has a length extending along a long axis of the substrate and a width extending along a short axis of the substrate. The method includes forming recessed regions into the back-side surface of the substrate at both ends of the slot that extend beyond the length of the slot.
