Patent ID: 8025925

Claim:
A heating apparatus performing a heating process for a coating liquid coated on a substrate, comprising: a hot plate at which said substrate is placed; a top plate for rectification provided above said hot plate to be opposed to said substrate; a protruding portion provided on said hot plate for supporting said substrate in such a manner that said substrate is isolated from an upper surface of said hot plate; a gas discharging part provided on one end side of said hot plate, said gas discharging part having an input for receiving heated gas therein, and a plurality of gas discharging ports that are located below said upper surface of said hot plate for discharging heated gas between said hot plate and said top plate to form a gas flow having a width that can cover a width of said substrate; an exhaust part provided on a side opposed to said gas discharging part with said hot plate interposed, said exhaust part having exhaust ports also located below said upper surface of said hot plate to suck and exhaust said gas; and a heating part provided at said hot plate and being capable of independently heating a first region in said substrate, which is adjacent to said exhaust part, and a second region in said substrate, which is located at the side of said gas discharging part with respect to said first region, and heating said first region at a temperature higher than said second region, wherein said gas flow from said gas discharging ports of said gas discharging part to said exhaust ports is between said substrate and said top plate, and between said substrate and said hot plate.
