Abstract
Target processing temperatures for a wafer and offset values are tabulated and stored in a temperature controller in advance. When a target processing temperature is changed, a hot plate temperature corresponding to the target processing temperature for the wafer is calculated based on the offset value in the table. Based on the calculated value, a heater controller controls a heater to change the hot plate temperature. Thereby, in a substrate heat processing apparatus for performing heat processing at different temperatures, an offset value corresponding to each temperature is automatically changed, whereby the substrate can be heated at an appropriate temperature.
