    Abstract: A layered hinge design providing an improved shock and vibration performance for a two-axis MEMS Micromirror featuring combs drive actuation with independent drive and control for rotating the Micromirror along two-axis of rotation. The two-axis MEMS Micromirror is fabricated using Double SOI wafer as the primary starting material. In addition, a plurality of actuation voltages are driven via conductive layers forming one or more hinges allowing the Micromirror to rotate along the two-axis of rotation. The layered hinge design achieves set angles that are highly stable over time and provides a robust and reliable micromirror that is easy to drive with multiple DC voltages, and moderately insensitive to temperature, shock and vibration.
