  • Patent number: 7629190
    Abstract: A method is disclosed for forming a micromechanical device. The method includes fully or partially forming one or more micromechanical structures multiple times on a first substrate. A second substrate is bonded onto the first substrate so as to cover the multiple areas each having one or more micromechanical structures, so as to form a substrate assembly. The substrate assembly is then separated into individual dies, each die having the one or more micromechanical structures held on a portion of the first substrate, with a portion of the second substrate bonded to the first substrate portion. Finally, the second substrate portion is removed from each die to expose the one or more micromechanical structures on the first substrate portion.
