Abstract:
A method for making a thin silicon suspended structure comprising the steps of:providing a glass wafer or substrate having a surface; providing an SOI wafer having an insulating layer disposed between a first silicon layer and a second silicon layer; forming a recess in said glass wafer surface; bonding said SOI wafer to said glass wafer surface such that at least part of said first silicon layer is bonded to said glass wafer surface so that at least part of said first silicon layer overhangs said recess; removing said second silicon layer of the SOI wafer; removing the insulating layer of the SOI wafer; and selectively patterning the first silicon layer of the SOI wafer after removing the insulating layer to form a thin silicon suspended structure that at least partially overhangs said recess.
