Abstract:
1. A substrate heating method, comprising: heating a substrate coated with a coating solution by a hot plate; transferring the substrate having been heated by the hot plate to a cooling plate, which is connected through a heat pipe provided in the cooling plate to a fin structure having cooling fins; moving the cooling plate supporting the substrate to a position remote from the hot plate to locate the fin structure connected to the cooling plate adjacent to a suction port of a first suction passage; and suctioning a gas existing around the fin structure through the suction port to generate a gas flow flowing into the suction port through a gap between adjacent fins of the fin structure, thereby cooling the cooling plate and the substrate placed thereon through heat transfer from the cooling plate to the fin structure, wherein: the substrate is heated while a top plate is arranged above the substrate and a gas flow flowing along the top plate and flowing into a suction port of a second suction passage is generated; and the gas flow flowing through the first suction passage merges into the gas flow flowing through the second suction passage.
