A semiconductor device includes a passivation layer, a first protective layer, an interconnect layer, and a second protective layer successively formed on a semiconductor substrate. The interconnect layer has an exposed portion, on which a barrier layer and a solder bump are formed. At least one of the passivation layer, the first protective layer, the interconnect layer and the second protective layer includes at least one slot formed in a region outside a conductive pad region.
