    Abstract: PROBLEM TO BE SOLVED: To provide a technique including a method and device for forming nozzles in a microelectromechanical device such as an ink jet print head.
    SOLUTION: The nozzles 460 are formed in a layer 420 prior to the layer 420 being bonded onto another portion 440 of the device. Forming the nozzles 460 in the layer 420 prior to bonding enables forming nozzles 460 that have a desired depth and a desired geometry. Selecting a particular geometry for the nozzles 460 can reduce the resistance to ink flow as well as improve the uniformity of the nozzles 460 across the microelectromechanical device.

    Abstract: A microfabricated device and method for forming a microfabricated device are described. A thin membrane including silicon (630) is formed on a silicon body (25) by bonding a silicon-on-insulator substrate (685) to a silicon substrate. The handle and insulator layers (695,690) of the silicon-on-insulator substrate are removed, leaving a thin membrane of silicon bonded to a silicon body such that no intervening layer of insulator material remains between the membrane and the body. A piezoelectric layer is bonded to the membrane.
