Semiconductor device

A semiconductor device includes: a semiconductor layer; a first region of a first conductivity type formed in the semiconductor layer and connected to a ground potential; a second region of a second conductivity type formed in the semiconductor layer; an insulating film formed on the semiconductor layer and covering the first region and the second region; an internal circuit; a signal terminal that drives the internal circuit or is drivable from the internal circuit; a first wiring connecting the internal circuit and the signal terminal; a resistance element that is formed on the insulating film, is provided midway along the first wiring, and includes a first resistor that faces the second region with the insulating film therebetween; and a second wiring which is connected to the first wiring on the side closer to the signal terminal than the resistance element, and which connects the first wiring and the second region. 一种半导体器件，其包括：半导体层；形成于所述半导体层的与接地电位连接的第1导电型的第1区域；形成于所述半导体层的第2导电型的第2区域；形成于所述半导体层上的覆盖所述第1区域和所述第
