Abstract: Wiring work without requiring a safety PLC is simplified even when a plurality of safety switches having a lock function are arranged. The plurality of safety switches are cascade-connected to a wiring unit. The wiring unit supplies power received via the power input unit (a VCC terminal or a GND terminal) to the plurality of safety switches. The wiring unit performs through-output of an OSSD input received from the most downstream safety switch to the outside of the wiring unit. The wiring unit outputs upstream-facing communication data COM (a lock input or the like) based on a lock instruction (LOCK). The wiring unit receives downstream-facing communication data COM (such as bundle data of AUX outputs) and outputs the communication data COM as individual AUX outputs.

Abstract: A diode formed by a polysilicon layer is disposed between a field oxide film and an interlayer insulating film, in a semiconductor substrate, at a front surface of the semiconductor substrate. One resist mask is used to form contact holes of the interlayer insulating film and contact trenches and a p+-type region of the polysilicon layer. The contact trenches are continuously formed from bottoms of the contact holes, respectively, in a depth direction. A low-resistance contact between the p+-type region and an anode electrode is formed at least at a bottom of the contact trench. During the formation of the p+-type region, while a p-type impurity is ion-implanted in an inner wall of the contact trench 3b, an n-type cathode region maintains an n-type conductivity thereof and a contact with a cathode electrode is formed at sidewalls of the contact trench.
