Abstract
The present invention is generally directed to a method and assembly for elevating and supporting a microstructure of a MEM system generally by engaging a positioning system of the MEM system with a first elevator lifter. The MEM system generally includes a first microstructure (such as a mirror) disposed in vertically spaced relation to a substrate. The positioning system generally includes an actuator assembly movably interconnected with the substrate, an elevator pivotally interconnected with the substrate and further interconnected with the microstructure, and a tether interconnecting the actuator assembly and the elevator. The first elevator lifter is provided to engage the elevator to lift/elevate the microstructure away from the substrate generally after fabrication of the MEM system and prior to utilizing the microstructure in operation of the MEM system.
