Patent ID: 7402255

Claim:
A method for making a MEMS mirror device, comprising: etching a first wafer to form: a bottom mirror layer comprising a web protruding from a bottom flange; an anchoring pad; bonding a second wafer having a bottom oxide layer atop the first wafer; etching the second wafer to form: a top mirror layer comprising a top flange and trenches on the top flange, the top flange being bonded atop the web of the bottom mirror layer to form a mirror; a beam connected to the top mirror layer; a first spring connecting the beam to a first bonding pad, the first bonding pad being bonded atop the anchoring pad; a plurality of rotational comb teeth connected to the beam; a first plurality of stationary comb teeth connected to a second bonding pad, the second bonding pad being bonded atop the anchoring pad.
