Abstract:
A heat processing apparatus comprising;a heating section having a hot plate for heating a substrate in a heat conduction manner;refrigeration medium for decreasing temperature of the hot plate in a heat exchange manner by bringing the refrigeration medium in direct or indirect-contact with the hot plate;a refrigeration section for storing the refrigeration medium while cooling;a transport mechanism for taking out the refrigeration medium from the refrigeration section, transporting the refrigeration medium to the heating section, mounting the refrigeration medium on the hot plate, picking up the refrigeration medium from the hot plate, taking out the refrigeration medium from the heating section, and transporting the refrigeration medium to the refrigeration section;setting means for setting a heat processing temperature for the substrate; anda controller for controlling temperature of the hot plate by using the refrigeration medium so as to reach the heat processing temperature set by the setting means.
