摘要: A bonded device having at least one porosified surface is disclosed. The porosification process introduces nanoporous holes into the microstructure of the bonding surfaces of the devices. The material property of a porosified material is softer as compared to a non-porosified material. For the same bonding conditions, the use of the porosified bonding surfaces enhances the bond strength of the bonded interface as compared to the non-porosified material.
