Polyimide wafer bonding

WebJan 9, 2024 · In our work, 4-inch LiNbO3 and LiNbO3/Cr/Au wafers are fabricated to silicon substrate by means of a polyimide bonding method, respectively. The low-temperature bonding process (≤100 °C) is also useful for heterostructure to avoid wafer fragmentation results from a coefficient of thermal expansion (CTE) mismatch. 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.
