Abstract: According to one embodiment, a controller calculates an estimation temperature profile, which represents a change with time in temperature of a substrate mounting surface in a state where a substrate is placed on a substrate stage, from warp amount information indicating a warp of the substrate. Further, the controller detects abnormality of a placement state of the substrate, on a basis of a difference between an actual measurement temperature profile, which represents a change with time in actual temperature measured by a temperature sensor in a state where the substrate is placed on the substrate stage, and the estimation temperature profile.

Abstract: According to one embodiment, there is provided a chemical liquid supply system including a chemical liquid supply apparatus and a monitoring apparatus. The chemical liquid supply apparatus includes a nozzle, a filter, a first pressure gauge, and a second pressure gauge. The first and the second pressure gauge are disposed on the pipeline, respectively at a chemical liquid supply-source side and chemical liquid delivery side of the filter. The monitoring apparatus is configured to determine a state of the filter based on first differential pressure time information in which a differential pressure is acquired in a period until a time point of a lapse of a predetermined time since a start of pneumatic feeding of the chemical liquid to the nozzle. The differential pressure is a difference between a first pressure value measured by the first pressure gauge and a second pressure value measured by the second pressure gauge.
