    • PROBLEM TO BE SOLVED: To realize a method for controlling a semiconductor manufacturing apparatus, which can perform reliable control over the apparatus while taking advantages of a PLC and a PC, and which can easily create or change its operation procedures.
      SOLUTION: Control of opening, closing or the like of valves provided in gas paths of a semiconductor manufacturing apparatus is carried out under control of a programmable logic controller(PLC) 11, the PC 13 converts commands of valve opening/closing operations, etc., described in the PLC 11 to names of devices such as valves to be operated and operation procedures of valve opening/closing, etc., and then stores them in the PC, the PC creates a step sequence in the form of a flowchart in the PC 13 with use of the device names and operation procedures, replaces instructions in the flowchart sequence by the above commands, outputs them to the PLC 11, accepts a control result from the PLC 11, and sequentially transmit the instructions to the PLC 11 to execute predetermined valve opening/closing operations, etc.
