Abstract
Disclosed is an EUV system element having a hydrogen diffusion barrier including a region implanted with species (e.g., ions energetic neutral atoms) of a non-hydrogen gaseous material. Also disclosed is a method of making such a component including the step of implanting species of a non-hydrogen gaseous material to form a hydrogen diffusion barrier and a method of treating an EUV system element including the step of implanting species of a non-hydrogen gaseous material to prevent hydrogen adsorption and diffusion. Also disclosed is subjecting an EUV system element to a flux of non-hydrogen gas ions to displace hydrogen ions in one or more layers of the EUV system element with the non-hydrogen gas species so that the gas ions protect the EUV system element against hydrogen damage.
