Applicazioni

Tungsten silicide is used in microelectronics as a contact material. It is also used as a shunt over polysilicon lines to increase their conductivity and increase signal speed. Further, it acts as a barrier layer between silicon and other metals. In addition to this, it is used in microelectro mechanical systems and for oxidation-resistant coatings. It is also employed as a replacement for earlier tungsten films.

Note

Incompatible with acids.
