CAS 10026-04-7

Silane, tetrachloro-

Description:

Tetrachlorosilane, also known as silane, tetrachloro- (CAS number 10026-04-7), is an inorganic compound characterized by its molecular formula SiCl₄. It is a colorless, volatile liquid with a pungent odor, and it is highly reactive, particularly with water, producing hydrochloric acid and siloxanes. This compound is primarily used in the production of silicon and silicon-based materials, including silicones and semiconductors. Tetrachlorosilane is also utilized in chemical vapor deposition processes for the fabrication of thin films in microelectronics. Due to its reactivity, it is classified as a hazardous material; it can cause severe irritation to the skin, eyes, and respiratory system upon exposure. Proper handling and storage in a controlled environment are essential to mitigate risks associated with its volatility and corrosive nature. Additionally, it is important to note that tetrachlorosilane should be kept away from moisture and incompatible substances to prevent hazardous reactions.

ALD Material
Atomic layer deposition (ALD) is a chemically self-limiting deposition technique that is based on the sequential use of a gaseous chemical process. A thin film (as fine as -0.1 Å per cycle) results from repeating the deposition sequence as many times as needed to reach a certain thickness. The major characteristic of the films is the resulting conformality and the controlled deposition manner. Precursor selection is key in ALD processes, namely finding molecules which will have enough reactivity to produce the desired films yet are stable enough to be handled and safely delivered to the reaction chamber.
