Abstract:
1. A substrate heating apparatus, comprising: a casing; a hot plate, arranged in the casing, adapted to heat a substrate coated with a coating solution; a cooling plate, arranged in the casing, adapted to support the substrate thereon, adapted to move between a first position in the casing in which the substrate is transferred between the cooling plate and an external substrate conveyer arranged outside the casing and a second position in the casing above the hot plate in which the substrate is transferred between the cooling plate and the hot plate, and adapted to cool the substrate having been heated by the hot plate; a cooling-plate driving mechanism adapted to move the cooling plate between the first position and the second position; a substrate support member adapted to temporarily support the substrate to transfer the substrate between the hot plate and the cooling plate; a substrate-support-member drive unit adapted to move the substrate support member; a heat pipe having a first end connected to the cooling plate, and a second end; a fin structure having cooling fins thermally connected to the second end of the heat pipe, and connected to the cooling plate such that the fin structure moves together with the cooling plate; and a first suction passage having a suction port opening into a space in the casing such that the suction port is located adjacent to the fin structure when the cooling plate is in the first position, whereby the cooling plate is cooled through the heat pipe when a gas in the casing is suctioned through the suction port to form a gas flow flowing through a gap between adjacent fins of the fin structure to cool the fin structure.
