Slotted substrate

摘要

The described embodiments relate to a slotted substrate (308) for use in a fluid ejecting device. One exemplary embodiment includes a substrate (308) having a thickness between generally opposing first (310) and second (312) surfaces. A slot (505) is received in the substrate (308). The slot (505) has a central region (505a) joined with at least one terminal region (505b). The central region (503a) extends between the first (310) and second (312) surfaces. The at least one terminal region (505b) includes, at least in part, a bowl-shaped portion that has a diameter (d) at the first surface (310) greater than a width (w) of the central region (503a) at the first surface (310).
