Patent ID: 7319267

Claim:
A semiconductor device including a semiconductor chip and a substrate, said semiconductor chip including an output circuit and a control circuit, said semiconductor chip being mounted on said substrate, said semiconductor device comprising: first wiring for connecting a power supply potential terminal of said control circuit and a power supply potential terminal of said output circuit; second wiring for connecting a grounding potential terminal of said control circuit and a grounding potential terminal of said output circuit; a first on-chip bypass capacitor disposed between said first wiring and said second wiring, said capacitor serving as a bypass for said control circuit; third wiring for connecting the electrode section of a power supply potential that is provided on said substrate, and the power supply potential terminal of said output circuit; fourth wiring for connecting the electrode section of a grounding potential that is provided on said substrate, and the grounding potential terminal of said output circuit; and a second on-chip bypass capacitor disposed between said third wiring and said fourth wiring, said capacitor serving as a bypass for said output circuit; wherein a resistor is provided on said first wiring between said first on-chip bypass capacitor and the power supply potential terminal of said output circuit, said resistor having a high resistivity compared with that of a wiring material used for forming said first to fourth wirings.
