摘要：In power supply and a semiconductor making apparatus and a semiconductor

fabricating method using the same, an abnormality can be detected when an offsetoccurs in a part constituting a closed-loop system of high-frequency power supply or dcpower supply for a semiconductor making apparatus. Power supply for receiving a powervalue setting signal to set strength of power and a power on/off instruction to set on oroff of outputting of the power interrupts the supply of the power even in a state in whicha subsequent power on/off instruction is on if a power sense signal according to a valueobtained by sensing the power exceeds a predetermined value when the power on/offinstruction is off.
