Abstract

According to this invention, a surface-treating apparatus capable of etching an object to be treated with high accuracy, suppressing discharging of a harmful gas deposited on the etched object in the air, and preventing the surface of the object from deposition/ attachment of reaction products and droplets is disclosed. The surface-treating apparatus includes a first process chamber for etching a loaded object to be treated by an activated etching gas, an exhausting member for setting the first process chamber at a low pressure, a cooling means for cooling the object loaded in the first process chamber, a second process chamber in which the object etched by the first process chamber is loaded, an exhausting member for setting the second process chamber at a low pressure, and an heating member for annealing the object loaded in the second process chamber.
