Step 1:
Begin with a glass wafer. Etch cavities in glass and pattern electrodes,
lines and bond pads.

Step 2:
Anodically bond SOI wafer to glass.

Step 3:
Etch back silicon handle wafer and buried oxide layer.

Step 4:
Deposit low stress metal. Lithographically pattern and DRIE etch to
release silicon microstructures.
