Abstract:
1. A method for operating a semiconductor processing apparatus that etching-processes a semiconductor wafer mounted on a stage placed in a container using a plasma generated therein, wherein the semiconductor processing apparatus comprises a setting device for setting a temperature of the semiconductor wafer during the process of etching and at least one operation condition of the semiconductor process apparatus based on the set temperature of the semiconductor wafer, the at least one operation condition including at least one of a temperature of a refrigerant which flows through an inside of the stage, a quantity of heat of a heater mounted in the stage, a pressure of gas introduced between the semiconductor wafer and the stage, and a high frequency power supplied to the stage, and a control device which controls an operation of the semiconductor processing apparatus, the method comprising the steps of: when receiving an instruction from the setting device to change the at least one operation condition, detecting a value of the operation condition; and adjusting operation of the semiconductor processing apparatus including the at least one operation condition thereof and performing etching processing so as to maintain a condition of the set temperature of the semiconductor wafer and to attain the instruction to change the at least one operation condition.
