Abstract:
A method for fabricating a semiconductor device comprising the steps of:forming an underlying insulator layer on a substrate,forming a metallic wiring layer on said underlying insulator layer,forming an oxidization-resisting metallic layer on said metallic wiring layer,removing said oxidization-resisting metallic layer and said metallic wiring layer except a predetermined part on said underlying insulator layer,forming a side wall insulator layer with a penetration resisting property against oxidizing gas on side walls of said oxidization-resisting metallic layer and said metallic wiring layer of said predetermined part,forming a silicon oxide layer over said oxidization-resisting metallic layer, said sidewall insulator layer and said underlying insulator layer,applying spin-on glass (SOG) application composed of silicon compound material, which comprises silazane bondings in its back bone, on said silicon oxide layer, andsintering said SOG application in an oxidizing gas atmosphere.
