After further process steps on the device wafer (temporary bonded on a
carrier), which generally include back thinning, lithography,
metallization, etching, through via processing, etc., the device wafer is
subsequently debonded from the carrier substrate before unloading into the
dedicated output format takes place. Dependent from the intermediate
material, various debond and cleaning approaches are possible. As for waxes
and thermo-plast materials a thermal-activated, mechanical slide-off is
utilized. For UV-activated tapes, UV-exposure and wedge-off debond is
utilized. All thinned substrates are safely processed within the EVG850DB
by a special handling system.
