Abstract
In an ink-jet printhead, the individual channels for ejecting ink onto a print medium are orientation dependently etched along the (111) planes perpendicular to the (110) surface orientation of a single crystal silicon wafer. The silicon wafer is bonded on a glass substrate to act as both a support and an etch stop in the etching process. The orientation of the channels within the silicon layer facilitates channels which are rectangular in cross section.
