Abstract:
An inspection apparatus includes: an acquisition part configured to acquire first coordinate information indicating a position of an inspection object on a stage and a plurality of pieces of second coordinate information indicating positions of a plurality of temperature sensors on the stage when performing an inspection of the inspection object; a calculation part configured to calculate a Mahalanobis distance between a position specified by an average vector of the first coordinate information and the positions of the plurality of temperature sensors; a selection part configured to select at least one temperature sensor including a temperature sensor having a smallest Mahalanobis distance, among the plurality of temperature sensors; and a controller configured to control a temperature of the inspection object using temperature data measured by the selected at least one temperature sensor.
