Silane

Silane, SiH₄, is a colourless, spontaneously flammable, high-pressure gas.

Applications
In the semiconductor industry, silane is used for:

• polycrystalline deposition for interconnects or masking
• growth of epitaxial silicon
• chemical vapour deposition of silicon dioxide, silicon nitride, silicon carbide, and refractory metal silicides
• implantation silicon sources, amorphous silicon devices such as photosensitive drums or solar cells
• thin layer deposition on flat glass.
