SEMICONDUCTOR DEVICE |
摘要 |
It is the object to minimize a magnetic influence, on the outside, of a semiconductor chip which is formed on a substrate includes inductor conductors. A semiconductor chip 2 including inductor conductors is mounted on a substrate 1 and a plurality of through holes 8 are formed in the area on the outside of the mounting position. Shielding members 4 are formed on the chip mounting side and the opposite side of the substrate 1 and in the through holes 8 so as to cover the semiconductor chip 2 with the shielding members 4 from both sides of the substrate 1. Therefore, magnetic fluxes from a circuit formed on the semiconductor chip 2 do not leak out from the shielding members 4, but circulate inside the shielding members 4. <IMAGE> |
