摘要 |
A polysilazane perhydride solution, prepared by dispensing polysilazane perhydride in a solvent containing carbon, is applied on a semiconductor substrate (1), thereby forming a coated film (6), which is heated, volatilizing solvent therein, thereby forming a polysilazane film (7), which is chemical-treated, so the polysilazane film (7) is changed to a silicon dioxide film (8).
