  • Abstract
    In this research we have designed and fabricated electromagnetically driven micromirror by combination of surface and bulk micromachining processes. Individual mirror plate and springs occupy relatively small area of 300/spl times/300 /spl mu/m/sup 2/. To obtain flat mirror surface, bulk silicon of thickness ranging from 10 to 20 /spl mu/m is used as a mirror plate. For the mirror plate to have substantial amount of angular deflection, aluminum is used as a spring material and crab-leg shaped spring is used.
