Description:

Tungsten silicide is a replacement for earlier tungsten films. Tungsten silicide is also used as a barrier layer between silicon and other metals, e.g. tungsten. Tungsten silicide is also of value towards use in micro electro mechanical systems, where it is mostly applied as thin films for fabrication of micro scale circuits.

Application:

It is used in microelectronics as a contact material, with resistivity 60–80 μΩ cm; it forms at 1000 °C. It is often used as a shunt over polysilicon lines to increase their conductivity and increase signal speed. Tungsten silicide layers can be prepared by chemical vapour deposition, e.g. using monocline or dichlorosilane with tungsten hexafluoride as source gases. The deposited film is non-Stoichiometric, and requires annealing to convert to more conductive Stoichiometric form.

Storage Conditions:

Airtight sealed, avoid light, and keep dry at room temperature.
