Substrate temperature adjustment apparatus for estimating a time taken until a substrate temperature falls within a target temperature range

摘要

A substrate temperature adjustment apparatus includes a temperature adjustment device for adjusting a temperature of a substrate, and a temperature measurement device for measuring a temperature of the temperature adjustment device, when the temperature is out of a target temperature range. The time taken until the temperature of the substrate falls within the target temperature range is predicted on the basis of the temperature of the temperature adjustment device measured by the temperature measurement device.
