Abstract:
1. A semiconductor module, comprising: a printed wiring board comprising an insulator with conductor patterns formed on both sides thereof; a semiconductor chip mounted on the printed wiring board and sealed with a resin, wherein a moisture penetration blocking sheet comprising a ceramic is adhered on the semiconductor chip surface opposite to the side that faces the printed wiring board via an adhesive layer so that the adhesive layer prevents the moisture penetration blocking sheet from directly contacting the semiconductor chip so that the moisture penetration blocking sheet is sufficiently spaced apart from the semiconductor chip so that the moisture penetration blocking sheet blocks moisture from reaching at least certain area(s) of the chip; wherein a lateral edge of the moisture penetration blocking sheet is spaced inside a periphery of the semiconductor chip as viewed from above so that the moisture penetration blocking sheet has a surface area less than that of the semiconductor chip; and a tuning circuit including a capacitor sealed by the resin and an antenna electrically connected to at least one antenna terminal, wherein the tuning circuit is for non-contact communication, and wherein the at least one antenna terminal is provided on the printed wiring board and includes a portion covered by the resin and another portion not covered by the resin.
