    摘要: A method of fabricating a multi-layered interconnection structure which comprises the steps of: forming a first wiring layer on a silicon oxide film having a compressive stress; forming a thick (2 to 3.5 .mu.m) fluorine-containing silicon oxide film at a temperature not higher than 200 .degree. C.; etching back the fluorine-containing silicon oxide film to flatten the surface of the film; forming a silicon oxide film having a compressive stress; forming a through-hole in position; and forming a second wiring layer. Since the fluorine-containing silicon oxide film is used as part of an insulating film, a resistance to cracking, flatness and reliability are significantly improved.
