A semiconductor device includes a semiconductor chip, an interposer, a surface circuit pattern, and a post array. The surface circuit pattern is formed on one surface of the interposer and includes chip side pads connected to an external connection pad of the semiconductor chip, junction pads, and interconnecting lines having an end connected to the chip side pads and another end connected to the junction pads. The interconnecting lines extend from the chip side pads toward an outer edge of the interposer. The post array includes conducting paths and insulating resin insulating the conductive paths from each other. The post array is arranged such that the conductive paths extend in a direction intersecting with the surface of the interposer. The conducting paths each have an end connected to the junction pad and another end to be connected to the printed wiring board. |
