Abstract
The present invention provides a silicon oxynitride film formation method capable of reducing energy cost, and also provides a substrate equipped with a silicon oxynitride film formed thereby. This method comprises the steps of: casting a film-formable coating composition containing a polysilazane compound on a substrate surface to form a coat; drying the coat to remove excess of the solvent therein; and then irradiating the dried coat with UV light at a temperature lower than 150° C.
