Abstract: A plasma shield assembly may include a guide component including first through holes connected to plasma generators that generate radicals using process gas, and a shield component detachably coupled to the guide component and disposed on a lower surface of the guide component, and including second through holes aligned with the first through holes to pass the radicals from the first through holes. The shield component may be spaced apart from the lower surface of the guide component with a gap formed between the shield component and the guide component. Bumper rings disposed adjacent to the second through holes to prevent the radicals from entering the gap.
