Description and Uses
Tetrakis(trimethylsilyloxy)silane (TTMS) is an organosilicon compound used as a precursor to prepare nanostructured organosilicon polymer films by plasma-enhanced chemical vapor deposition (PECVD) at atmospheric pressure. TTMS along with cyclohexane can also be used to synthesize low dielectric constant SiCOH films by PECVD method.
