发明名称 Low-pressure dryer and low-pressure drying method
摘要 A low-pressure dryer dries a substrate applied a coating solution thereon at low pressure. The dryer includes an airtight chamber installing a substrate table to place the substrate thereon; a diffuser plate, provided as facing the substrate placed on the substrate table with a gap, for discharging gas existing in the gap toward outside, the diffuser plate having a size almost the same as or larger than the substrate; a substrate-temperature adjuster, installed in the substrate table, for adjusting a temperature of the substrate; and a decompression mechanism for decompressing the airtight chamber. The diffuser plate has a temperature adjuster for making temperature adjustments to have a temperature difference between a first region and a second region of the diffuser plate, the first region facing a center region of the substrate, the second region being outside the first region and including a region facing an outer region of the substrate.
