Abstract:
An electrostatic chuck, a substrate processing apparatus, and a method of manufacturing a semiconductor device are provided. The electrostatic chuck comprises a chuck base, an insulation plate on the chuck base, a first heater comprising a cell heater in the insulation plate, and a heater controller configured to control the cell heater. The heater controller obtains a resistance of the cell heater and compares the resistance with a threshold value to control a heating power provided to the cell heater.
