TETRAKIS(DIMETHYLAMINO)SILANE Usage And Synthesis

Uses

Silicon dioxide thin films prepared by chemical vapor deposition from tetrakis (dimethylamino) silane and ozone. Aminosilanes mere prepared by methods all essentially similar, and only the 15olation of tetrakis-(dimethylamino)-silane.

Safety Profile

A poison by ingestion and slam contact. A severe eye irritant. When heated to decomposition it emits toxic vapors of NOx.
