A semiconductor anti-interference band distributed on peripheries of partial of regional circuits in an integrated circuit is assembled by an unequal number of PNP structures; two metal bands are disposed on the surface layer of the integrated circuit, wherein one band connects with GND and the other connects with Vcc; to add positive voltage at Vcc increases the charge at P&plus; tip thereby generating a parasitic capacitance on a poly layer between two P&plus; tips and limiting a noisy signal within the distributed area; furthermore, the P&plus; tip and an N well connect to produce a positive voltage zone in a large area to forcefully prevent a noisy signal current from passing through and make it discharge at a ground end with lower voltage so as to achieve the electromagnetic anti-interference function of the integrated circuit.
