The purpose of this point is that how the CuNiAu bump replaces Au bump. Besides lowering the cost of package obviously, it also keeps the same characteristic of Au bump and raises bump hardness which is to release the bonding force and stabilize bonding process. In order to confirm hardness performance of CuNiAu bump. There are 3 kinds of collocation for applying the different thickness. DOE plan is to respectively choose 2 kinds of thickness in Cu/Ni/Au metal and then mix 3 anneal conditions. After experiment is completed, bump hardness performance under different combinations will be confirmed by measuring hardness before/after anneal process. Additionally, bump performance is also confirmed by the reliability test. Actually, the authors have finished the Tech evaluation on higher hardness spec.
