1. An ink-jet printhead comprising:

  • a substrate defining a main surface;

    a single crystal silicon wafer bonded to the main surface of the substrate, the silicon wafer being oriented with a (110) plane parallel to the main surface of the substrate; and

    a plurality of parallel channels defined in the silicon wafer, with a portion of the main surface of the substrate being exposed within each channel, wherein each parallel channel defines sidewalls in the silicon wafer which are perpendicular to the main surface of the substrate.
