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.

Package substrate and semiconductor package including the same

A semiconductor package including a redistribution substrate with a first insulating layer, one or more second insulating layers on the first insulating layer, and a plurality of redistribution layers. The first insulating layer includes a first photosensitive resin having an elongation of 60% or more and toughness of 70 mJ/mmor more. The one or more second insulating layers include a second photosensitive resin having an elongation in a range of 10% to 40% and toughness of 40 mJ/mm.

Semiconductor package

A semiconductor package includes: a redistribution layer including a plurality of redistribution insulating layers, a plurality of redistribution line patterns that constitute lower wiring layers, and a plurality of redistribution vias that are connected to some of the plurality of redistribution line patterns while penetrating at least one of the plurality of redistribution insulating layers; at least one semiconductor chip arranged on the redistribution layer; an expanded layer surrounding the at least one semiconductor chip on the redistribution layer; and a cover wiring layer including at least one base insulating layer, a plurality of wiring patterns that constitute upper wiring layers, and a plurality of conductive vias that are connected to some of the plurality of wiring patterns while penetrating the at least one base insulating layer.

Semiconductor package, and package on package having the same

A semiconductor package includes a connection structure including a first insulating layer, a first redistribution layer disposed on the first insulating layer, and a first connection via penetrating through the first insulating layer and connected to the first redistribution layer, a semiconductor chip disposed on the connection structure, an encapsulant covering at least a portion of the semiconductor chip, a second insulating layer disposed on the encapsulant, a second redistribution layer including a signal line disposed on the encapsulant, and a heat dissipation layer disposed on the encapsulant and electrically insulated from the signal line.
