Abstract: Disclosed is a method of treating a substrate by using a substrate treating apparatus generating plasma in a treatment space by applying microwaves, the method including: a plasma treatment operation of treating a substrate with the plasma; a replacement operation in which the plasma treatment operation is performed a preset number of times and a component included in the substrate treating apparatus is replaced; and a backup operation of backing up the substrate treating apparatus after the replacement operation, in which the backup operation includes a bake purge operation for removing byproducts present in the component.
