The present invention relates to a composition for treating a semiconductor substrate, and particularly to a composition for treating an edge portion of a wafer coated with polysilazane.

According to the composition for treating a semiconductor substrate according to the present invention, it is possible to uniformly maintain the quality of the composition in terms of management and to uniformly treat the boundary of the wafer in terms of processing. In addition, by improving the straightness of the boundary portion where polysilazane is removed, it is possible to significantly reduce the defect rate of the product and to stably improve the productivity yield.
