The m-Si mirror layer is transfer bonded from a silicon-on-insulator (SOI) donor wafer with adhesive wafer bonding towards an intermediate patterned polymer spacer layer and clamped with metal plating. We present a CMOS compatible, bond alignment-free fabrication scheme offering the potential for high air gap distances between substrate and mirrors and we show first measurements of the fabricated mirrors. ©2009 IEEE.en621CMOS-integrable piston-type micro-mirror array for adaptive optics made of mono-crystalline silicon using 3-D integrationconference paper
