Report Overview

Tetraethylorthosilicate (TEOS) is a liquid source material used in CVD systems for deposition of doped and undoped silicon dioxide films. TEOS is a stable, non-pyrophoric, non-corrosive liquid, and thereby is a preferable alternative to processes employing silane or similar compounds. TEOS is used for undoped SiO2 films and with liquid dopants to deposit BPTEOS films. Applications for TEOS include undoped and doped interlayer dielectrics, inter-metal dielectrics, pre-metal dielectrics, sidewall spacers and trench-filling applications. It is used as a replacement for silane and other pyrophoric silicon sources.

The global High Purity Tetraethyl Orthosilicate market size was estimated at USD 154 million in 2023 and is projected to reach USD 239.31 million by 2030, exhibiting a CAGR of 6.50% during the forecast period.
