Silan

Silanes are compounds of silicon and hydrogen, including monosilane (SiH4), disilane (Si2H6), and some higher-order silicon-hydrogen compounds. Among them, monosilane is the most common, and monosilane is sometimes abbreviated as silane. Silane is a colorless, air-reactive and suffocating gas.

Production and Applications of Electronic-Grade Silane Gas

Process

Silane is produced by the reduction of silicon tetrachloride by metal hydrides such as lithium or calcium aluminum hydride. Silane is produced by treatment of magnesium silicide with hydrochloric acid.
GazSilan
CAS No.7803-62-5
Purity≥99.9%

Applications

Glass

Silane is used in the production of special glasses to provide a reflective coating.

Semiconductors

Silane is one of the basic materials of the silicon semi-conductor industry. It is used as a source of silicon for growing polycrystalline and epitaxial (monocrystalline) silicon, silicon dioxide, silicon nitride and doping of gallium arsenide. 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.

Photovoltaic Cells

Silane is also used in the production of photovoltaic cells.

Fiber Optic

Silane is used in the production process of optical fibres.

Frequently Asked Question

What is the formula for silane?

The chemical formula of silane is SiH4

What are the silane gas uses?

Silane has become the most important special gas used in semiconductor microelectronics process, and is used in the preparation of various microelectronic films, including single crystal film, microcrystal, polycrystal, silicon oxide, silicon nitride, metal silicide, etc. Not only used for silicon devices and silicon integrated circuits, but also for compound semiconductor devices (gallium arsenide, silicon carbide, etc.).

What is liquid silane coupling agent?

Silane coupling agent is a chemical agent, mainly used in glass fiber reinforced plastics. The molecular structure formula of silane coupling agent is generally Y-R-Si(OR)3. Siloxy groups are reactive towards inorganics, organofunctional groups are reactive or compatible with organics.
