WebIn this study we succeeded in easy bonding and debonding PI films on glass wafers directly by using Si or Cu intermediate layer with Fe ultra-thin layer at room temperature. The Si or Cu layer was deposited on polyimide films and glass wafers by Ar ion beam sputtering, and then film and wafer ware brought into contact and pressed in high vacuum. WebA combination of material stack, CMP parameters and design rules enabled us to obtain defect-free bond interface across the wafer. Scanning acoustic microscopy, FIB-SEM and TEM cross-sections demonstrated a perfect SiO 2 /SiO 2 bonding as well as excellent Ti/Ti connections for Ti pads as small as 3×3 μm 2.
