Beschreibung
Zusammenfassung:	According to one embodiment, a substrate treatment device includes a placement stand configured to rotate a substrate, a cooling part configured to supply a cooling gas into a space between the placement stand and the substrate, a liquid supplier configured to supply a liquid on a surface of the substrate opposite to the placement stand, and a controller controlling a rotation speed of the substrate, a flow rate of the cooling gas, or a supply amount of the liquid. The controller sets the liquid on the surface of the substrate to be in a supercooled state, forms a frozen film by freezing the liquid in the super cooled state, and causes crack to generate in the frozen film by decreasing a temperature of the frozen film.
