Abstract: A metal gasket for a semiconductor fabrication chamber capable of preventing base plate metal contamination in the chamber, wherein the metal gasket includes a diffusion barrier layer interposed between a base plate and an anti-corrosive coating layer, and wherein the diffusion barrier layer prevents elements of the base plate from being diffused to the anti-corrosive coating layer. Accordingly, the diffusion barrier layer prevents attack on the anti-corrosive coating layer.
