Contact bumps methods of making contact bumps

Contact bumps between a contact pad and a substrate can include recesses and protrusions that can mate with the material of the substrate. The irregular mating surfaces between the contact bumps and the contact pads can enhance the bonding strength of the contacts, for example, against shear and ten...
