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. The invention
is also directed to a method for forming a micromechanical device,
including: forming one or more micromechanical structures in one or more
areas on a first substrate; bonding caps onto the first substrate so as
to cover the one or more areas each having one or more micromechanical
structures, so as to form a substrate assembly; after a period of time,
removing the caps to expose the one or more micromechanical structures.
During the period of time between bonding the caps and later removing the
caps, the substrate assembly can be singulated, inspected, irradiated,
annealed, die attached, shipped and/or stored.
