Abstract
The ringing of a switching waveform of a semiconductor device is restrained. For example, an interconnect (L) is laid which functions as a source of a power transistor (Q) and a cathode of a diode (D), and further functioning as a drain of a power transistor (Q) and an anode of a diode (D). In other words, a power transistor and a diode coupled to this power transistor in series are formed in the same semiconductor chip; and further an interconnect functioning as a drain of the power transistor and an interconnect functioning as an anode of the diode are made common to each other. This structure makes it possible to decrease a parasite inductance between the power transistor and the diode coupled to each other in series.
