    摘要: Embodiments generally relate to a chamber component to be used in plasma processing chambers for semiconductor or display processing. In one embodiment, a chamber component includes a textured surface having a surface roughness ranging from about 150 microinches to about 450 microinches and a coating layer disposed on the textured surface. The coating layer may be a silicon layer having a purity ranging from about 90 weight percent to about 99 weight percent, a thickness ranging from about 50 microns to about 500 microns, and an electrical resistivity ranging from about 1 E-3 ohm*m to about 1 E3 ohm*m. The coating layer provides strong adhesion for materials deposited in the plasma processing chamber, which reduces the materials peeling from the chamber component. The coating layer also enables oxygen plasma cleaning for further reducing materials deposited on the chamber component and provides the protection of the textured surface located therebelow.

    摘要: Extreme ultraviolet (EUV) mask blanks, methods for their manufacture and production systems therefor are disclosed. The EUV mask blanks comprise a substrate; a multilayer stack of reflective layers on the substrate; a capping layer on the multilayer stack of reflecting layers; and an absorber layer on the capping layer, the absorber layer made from tellurium, germanium and antimony.
