Abstract :
This paper presents very reliable and stable micro- mirrors made of hydrogenated microcrystalline SiGe (muc-SiGe:H) at temperatures that would allow processing above standard CMOS circuitry. Very flat micro-mirrors with sizes ranging between 7.5 x 7.5 and 16 x 16 mum2 size and submicron hinges are fabricated. No hinge creep is observed over a period of 20 days and no fatigue damage is seen after 5 x 1010 cycles.
