- the substrate when a heater is provided in the substrate processing container, the substrate can be quickly heated, and the temperature uniformity of the substrate can be improved. As a result, the substrate processing quality can be improved, and the throughput can be improved.
- the entire substrate processing container including its attached parts can be formed thin. Therefore, when constructing a substrate processing system by stacking substrate processing containers in multiple stages, it is possible to reduce the size of the entire system.
