摘要
Metal films can be used as bonding layers at wafer-level in manufacturing processes for device assembly as well as just for electrical integration of different components. One has to distinguish between two categories of processes: metal thermo-compression bonding on one side, and bonding with formation of a eutectic or an intermetallic alloy layer. The different process principles determine also the applications area for each. From electrical interconnections to wafer-level packaging (with special emphasis on vacuum packaging) metal wafer bonding is a very important technology in manufacturing processes.
