Applications

Copper silicide thin film is used for passivation of copper-based chips, where it serves to suppress diffusion and electromigration and serves as a diffusion barrier. It is involved in the direct process, the industrial route to organosilicon compounds.

Notes

Stable under recommended storage conditions. Store in cool, dry conditions in well sealed containers.
