Abstract:
A semiconductor device and method utilizing a dummy structure in association with a redistribution layer is provided. By providing the dummy structure adjacent to the redistribution layer, damage to the redistribution layer may be reduced from a patterning of an overlying passivation layer, such as by laser drilling. By reducing or eliminating the damage caused by the patterning, a more effective bond to an overlying structure, such as a package, may be achieved.
