Abstract

The fluorine doped TEOS films obtained using an inorganic gaseous dopant source (SiF4) and an organic liquid dopant source (TEFS) are described. The stability of fluorine in these films is strongly dependent on process conditions. The limit of stability for the most stable films is described. The gap fill capability of these films was found to depend strongly on the type of the fluorine precursor.
