Abstract:
1. A substrate processing method, comprising: a preparation step of preparing a solidification liquid to be supplied to a substrate in a supercooled liquid state; a solidified material forming step of supplying the solidification liquid prepared in the preparation step to the substrate via a space and forming a solidified material of the solidification liquid on the substrate; and a removing step of removing the solidified material of the solidification liquid on the substrate, wherein the solidification liquid is solidified by an external stimulus that is at least one of a landing impact of the solidification liquid onto a surface of the substrate and applying vibration transmitted from the substrate; and the solidified material forming step is for changing the thickness of the solidified material of the solidification liquid on the substrate within the plane of the substrate by supplying a solidification liquid in a supercooled liquid state onto the solidified material of the solidification liquid on the substrate.
