Abstract

Abstract Method of forming a pattern on a semiconductor wafer, the temperature of the semiconductor wafer being detected by a thermocouple. When the detected temperature is at a specified value which indicates that the deformation of the semiconductor wafer is within an allowable range, a step of forming a pattern on the semiconductor wafer is performed. This forming method improves the accuracy in forming the pattern. Also, in a method of inspecting a pattern on a semiconductor wafer, the temperature of the semiconductor wafer is detected using a thermocouple. When the detected temperature is at a specified value which indicates that the deformation of the semiconductor wafer is within an allowable range, a step of inspecting a pattern on the semiconductor wafer is performed. This inspecting method improves the accuracy in inspecting the pattern.
