METHOD FOR CONTROLLING TEMPERATURE OF SUBSTRATE SUPPORT AND INSPECTION APPARATUS

A method for adjusting a temperature of a substrate support is provided. In an apparatus for inspecting a target device, a substrate placement surface of the substrate support is divided into multiple regions and a heater is disposed in each of the multiple regions. The method comprises controlling the heater in a main region corresponding to the target device such that a temperature of the main region becomes a set temperature, and controlling the heater in a sub-region adjacent to the main region. When overshoot has not occurred in the temperature of the main region, the heater in the sub-region is controlled such that a temperature difference between the main region and the sub-region becomes a predetermined value, and when overshoot has occurred, the heater of the sub-region is controlled such that a difference between the set temperature and the temperature in the sub-region becomes the predetermined value.
