Abstract
An insulating film which enables not only to obtain a good film quality but to achieve an excellent filling property, thick film formation and planarization simultaneously, an insulating film forming coating solution for forming the insulating film, and a method of manufacturing the insulating film are set forth. An insulating film forming coating solution containing as a main component a solution of a polymer obtained by co-hydrolysis of trialkoxysilane expressed by a general formula, SiH(OR) —, methyltrialkoxysilane expressed by a general formula, SiCH (OR) —, and tetraalkoxysilane expressed by a general formula, Si(OR) is coated on a semiconductor substrate ( ) having a step portion, and after it is heated and dried in an inert gas atmosphere, an insulating film ( ) which is composed of a silane-derived compound expressed by a general formula, SiH (CH ) O , where, 0<x<1, 0<y<1, x+y≦1 is formed.
