| 摘要 |
A semiconductor device according to the present invention includes a wiring substrate having a chip mounting face on which a connected portion is formed, a semiconductor chip having an element forming face on which externally connecting terminals are formed, the externally connecting terminals being electrically connected to the connected portion, and a resin-sealed layer formed between the wiring substrate and the semiconductor chip so as to cover at least a periphery of the semiconductor chip. The wiring substrate has a through hole bored from the chip mounting face to an undersurface thereof. Part of the through hole is formed outside a chip mounting region of the wiring substrate. |
