A semiconductor chip or wafer comprises a passivation layer and a circuit line. The passivation layer comprises an inorganic layer. The circuit line is over and in touch with the inorganic layer of the passivation layer, wherein the circuit line comprises a first contact point connected to only one second contact point exposed by an opening in the passivation layer, and the positions of the first contact point and the only one second contact point from a top view are different, and the first contact point is used to be wirebonded thereto.
