Method and structure for wafer to wafer bonding in semiconductor packaging
Abstract:
A method for wafer to wafer bonding in semiconductor packaging provides for roughening the bonding surfaces in one embodiment. Also provided is a method for passivating the bonding surfaces with a lower melting point material that becomes forced away from the bonding interface during bonding. Also provided is a method for forming an eutectic at the bonding interface to reduce the impact of any native oxide formation at the bonding interface.
