Webwafer thickness may be anywhere from about 10 μm to 150 μm. If the device wafer is thinner than 150 μm it is possible to process the thin wafer through various backside process steps if the thinned wafer is on a carrier wafer. There are several methods for accomplishing the temporary bonding process. Regardless of the temporary bonding meth- WebBy altering the silanol group, the glass substrate obtains an enhanced hydrophilic characteristic for better adhesion.
