Abstract:
1. A semiconductor package on package comprising: a lower package; an upper package stacked over the lower package; and a plurality of conductive wire connectors, each of the conductive wire connectors electrically connecting the upper package and the tower package and having a wire connection of a plug-socket shape, wherein each of the conductive wire connectors comprises: a plug wire combined to one of an upper portion of the lower package and a lower portion of the upper package; and a socket wire combined to the other of the upper portion of the lower package and the lower portion of the upper package, wherein the plug wire is plugged in the socket wire, and wherein the socket wire comprises a first wire and a second wire, each of the first and second wires having both end points combined to any one of the upper portion of the lower package and the lower portion of the upper package and having at least one apex, wherein the first and second wires have an interval therebetween such that the plug wire can be plugged in between the first wire and the second wire, and the interval at one end between the first wire and the second wire is different from the interval at the other end between the first wire and the second wire.
