Abstract:
1. A temperature measurement apparatus used for a heat treatment apparatus including a process container, in which a rotating table for mounting a substrate is provided, and a heater for heating the process container, comprising: a radiation temperature measurement unit configured to measure the temperature of plural temperature measurement areas on a surface of the rotating table in a radius direction of the rotating table by scanning the surface of the rotating table in the radius direction; a temperature map generating unit that a temperature data display processing unit that displays a temperature profile of the rotating table based on the temperature and the address stored in the storing unit by the temperature map generating unit, wherein the radiation temperature measurement unit includes wherein the radiation temperature measurement unit is configured to scan the surface of the rotating table in the radius direction such that a temperature measurement area on the surface of the rotating table shifts in the radius direction in accordance with the rotation of the rotating body to measure the temperature of plural temperature measurement areas.
