Patent ID: 7541214

Claim:
A method of manufacturing a micro-electro-mechanical (MEMS) device, comprising the steps of: providing a substrate wafer having electrical elements, and a second wafer; bonding said substrate wafer and said second wafer with an adhesive or epoxy layer; patterning a plurality of via holes and/or openings in said second wafer and said adhesive layer; etching said via holes and/or openings through said second wafer and said adhesive layer; depositing metal layers in said via holes to form electrical interconnects between said second wafer and said substrate wafer; etching said second wafer with patterns of suspended structures and fixed structures; etching said adhesive layer with undercut to said second wafer, forming said suspended structures and said fixed structures from seconded wafer; wherein said electrical interconnects and/or said adhesive layer jointly or independently support or anchor said suspended structures.
