WebMay 30, 2024 · TEOS. Download Image. UltraPur™ TEOS is a liquid source material used in CVD systems for deposition of doped and undoped dioxide films. Stable, non-pyrophoric. Non-corrosive liquid. Preferable alternative to processes employing silane or similar compounds. Standard shelf life of 24 months. Interested in TEOS? WebTEOS / Oxygen Thermal CVD. TEOS is tetra-ethyl-ortho-silicate, or equivalently tetra-ethoxy-silane: TEOS is a liquid at room temperature, with a vapor pressure of about 1.5 Torr. TEOS slowly hydrolyzes into silicon dioxide and ethanol when in contact with ambient moisture, but its flammability and toxicity are similar to that of an alcohol.
