Abstract

The embodiments of diffusion barrier layer described above provide mechanisms for forming a copper diffusion barrier layer to prevent device degradation for hybrid bonding of wafers. The diffusion barrier layer(s) encircles the copper-containing conductive pads used for hybrid bonding. The diffusion barrier layer can be on one of the two bonding wafers or on both bonding wafers.
