Dursox is a thin but durable silicon oxide (SiO) high purity barrier coating that prevents semiconductor tool corrosion and erosion. Our patented CVD process bonds super high purity silicon to stainless steel, alloy, glass, and ceramic surfaces. The micro-thin coating penetrates small holes, inner cavities, and narrow bore tubes without significant change in component tolerance. Dursox will deform with part surfaces, allowing a leak-free seal or radius bend while maintaining high dimensional tolerance.
Semiconductor manufacturers have found a new weapon in the struggle for improved yields, higher purity, and reduced cost. Corrosives commonly used in semiconductor manufacturing cause yield robbing ion contamination, resulting in wafer contamination, higher maintenance and increased burn-in time.
Dursox® is the ideal coating wherever a high purity, durable, corrosion resistant coating is needed, applications range from semiconductor manufacturing, to research, and instrumentation corrosion. Corrosives commonly used in semiconductor manufacturing cause yield robbing ion contamination, resulting in wafer contamination, higher maintenance and increased burn-in time. Our CVD coating protects parts from corrosive attack while making the surface non reactive and contaminant free, improving yield, eliminating process contamination and reducing tool burn-in.

Dursox® makes semiconductor manufacturing flowpaths and critical surfaces non reactive and corrosion resistant, preventing process contamination and improving yield. Our product is superior to ceramic coatings like yttria, offering better stability, no delamination, and improved durability even in high stress areas like conflat sealing surfaces.
Dursox® is a high purity silicon oxide layer that contains no metals, assuring no leaching of metal ions into process streams. XPS data show our CVD coating contains only silicon, oxygen and carbon, making it the ideal barrier coating for semiconductor manufacturing applications.
Our coatings offer significant corrosion resistance when applied to stainless steel and other alloys, preventing contamination and extending component life. See our semiconductor chemical compatibility list.
