Patent ID: 8299599

Claim:
A semiconductor device comprising a first semiconductor chip having a first side and a second side facing the first side, wherein: a first circuit, a second circuit, a first diode for detecting the heat generation of the first circuit, a second diode for detecting the heat generation of the second circuit, and plural first pad electrodes are formed for the first semiconductor chip, the first circuit is arranged so as to lie nearer to the first side instead of the second side in the main surface of the first semiconductor chip, the second circuit is arranged between the first circuit and the second side in the main surface of the first semiconductor chip, the first diode is arranged so as to lie nearer to the first side instead of the second circuit in the main surface of the first semiconductor chip, the second diode is arranged so as to lie nearer to the second side instead of the first circuit in the main surface of the first semiconductor chip, the plural first pad electrodes include a first pad electrode for the source connected electrically to the first circuit and a second pad electrode for the source connected electrically to the second circuit, and at least one among the plural first pad electrodes excluding the first and second pad electrodes for the source is arranged between the first diode and the second diode in the main surface of the first semiconductor chip.
