  • Publication number: 20020187423
    Abstract: A substrate coated with a coating solution, for example, a resist solution is heated at a predetermined temperature, thereafter putted in a non-heated state, and then heated at a second predetermined temperature. Alternatively, a heating process in which a substrate coated with a resist solution is heated and a non-heated process in which the substrate is putted in a non-heated state are repeated a plurality of times. The adoption of the above treating methods can prevent the occurrence of transfer which is an index of ununiformity of film thickness of a resist solution and the like and change in line width of a circuit pattern, thus improving yield in substrate treatment.

  • Patent number: 6443641
    Abstract: Just after resist solution is coated on a substrate, it is dried substantially in a non-heating state. In reality, inertia gas or the like is blown from a shower head to the substrate. Thus, the resist solution coated on the substrate is dried. Consequently, transfer marks that cause the film thickness of resist film to be unequal and the line width of a circuit pattern to fluctuate can be prevented.

  • Patent number: 6087632
    Abstract: A heat processing device includes a hot plate on which a substrate is placed, a heater press-fitted in the hot plate for heating the substrate through the hot plate, and a reflecting plate facing an underside and side faces of the hot plate at a distance therefrom for reflecting heat radiated from the hot plate. An outside frame is arranged on the surface of the hot plate so as to surround the substrate.
