Abstract
A package substrate may include a plurality of stacked insulation layers, a plurality of RDLs and a pair of impedance patterns. The RDLs may be arranged between the insulation layers. The impedance patterns may be arranged on an upper surface of at least one of the insulation layers. The impedance patterns may have an insulation length corresponding to a summed length of thicknesses of at least two insulation layers among the plurality of the insulation layers. Thus, a dummy conductive pattern may not be arranged between the impedance patterns and the RDL so that only the insulation layer may exist between the impedance patterns and the RDL. As a result, the insulation length of the impedance patterns may correspond to the summed length of the thicknesses of the at least two insulation layers.
