Semiconductor device possessing electromagnetic interference shielding and substrate band

A semiconductor device and a substrate band are disclosed. The semiconductor device comprises a substrate and a conductive block arranged on a surface of the substrate. The substrate comprises a grounded conductive pattern on the surface of the substrate. The grounded conductive pattern surrounds a target area. The conductive block is electrically connected to the grounded conductive pattern and provides electromagnetic interference (EMI) shielding for the target area at a transverse direction of the surface of the substrate.
