Patent ID: 8318524

Claim:
A method comprising: providing a double sided polished wafer; depositing a reflector on one side of the wafer and an anti-reflection coating on the opposing side of the wafer; selectively disposing a patterned photoresist layer on the reflector; attaching a handle wafer to the anti-reflection coating on the opposing side of the wafer; selectively etching through the reflector on one side of the wafer, the anti-reflection coating on the opposing side of the wafer and the wafer to the handle wafer to define a flexure mold; disposing a resilient polymer into the flexure mold to form elastomeric flexures; removing the handle wafer; providing a double sided polished reference plate with a reflector on one side of the reference plate and an anti-reflection coating on the opposing side of the reference plate; and disposing the reference plate onto and opposing the wafer separated by spacers aligned with respect to the wafer and having the corresponding reflectors on the wafer and reference plate facing each other to form a Fabry-Perot interferometric sensor.
