Description
- Application: Tetraethyl orthosilicate (TEOS) is an oxygen containing precursor of Si used for the deposition of:Si oxideOxycarbideDoped silicateSilanolSiloxane polymerOrganosilicon thin filmsThe films can be deposited at low temperatues (<250 °C). TEOS is also used to deposit mesoporous and nanoporous thin films of silica. These porous films can be doped during deposition to further enhance their properties.
