Abstract:
1. A method of heat processing of a substrate on which a chemically amplified resist film is formed comprising the steps of: a first step of increasing the temperature of the substrate from a predetermined low temperature to a predetermined intermediate temperature by heating by a heating plate after the substrate is exposed, the predetermined intermediate temperature being lower than a predetermined reaction temperature at which the chemically amplified resist film reacts; a second step of maintaining the substrate at the predetermined intermediate temperature for a predetermined period of time; and a third step of increasing the temperature of the substrate to the predetermined high temperature that is higher than the predetermined reaction temperature; and baking said substrate at said predetermined high temperature; wherein the predetermined low temperature is less than the predetermined intermediate temperature and the predetermined intermediate temperature is lower than the predetermined high temperature, wherein said respective first to third steps are performed while the substrate is housed in a same heating chamber, and wherein said first step and said second step are performed on a first heating plate for mounting the substrate thereon and heating the substrate, and said third step is performed on a second heating plate for mounting the substrate thereon and heating the substrate.
