Abstract

Embodiments of the present invention generally provide methods for forming a silicon nitride layer on a substrate. In one embodiment, a method of forming a silicon nitride layer using remote plasma chemical vapor deposition (CVD) at a temperature that is less than 300 degrees Celsius is disclosed. The precursors for the remote plasma CVD process include tris(dimethylamino)silane (TRIS), dichlorosilane (DCS), trisilylamine (TSA), bis-t-butylaminosilane (BTBAS), hexachlorodisilane (HCDS) or hexamethylcyclotrisilazane (HMCTZ).
