| Outline of Final Research Achievements |
Signal traces or power supply lines on a printed circuit board (PCB) and an LSI interposer are coupled with the other conductors. The coupling affects it's operation or causes large emissions and degradation of immunity to RF disturbance. High frequency electromagnetic couplings in an IC, an interposer and a PCB are focused in this study, and construction methods of equivalent circuits which express these couplings are proposed. The circuit parameters, C and L, in the proposed equivalent circuit for the PCB and the interposer are defined using electromagnetic energy. In addition, an equivalent circuit model of CMOS with a substrate coupling are extracted by S parameter measurement, and resistances of substrate are measured. Finally, an equivalent circuit of a commercial IC is constructed using measurement and general information of this IC. Measurement results are in good agreement with results of immunity estimation to conducted disturbance using the proposed equivalent circuit.
