2. Silane is also used as a dopant in the production of compound semiconductor devices, for chemical vapour deposition of refractory metal silicides, and for deposition of amorphous silicon on photocopier drums.
3. Silane is also used in the production of photovoltaic cells.
4. Silane is used in the production process of optical fibres. Silane is used as a reducing reagent in organic and organo-metallic chemistry.
