Abstract
According to one embodiment a substrate treatment apparatus removes foreign matter from a surface of a substrate by forming a frozen film at the surface of the substrate, incorporating, into the frozen film, the foreign matter adhered to the surface of the substrate, and thawing the frozen film including the foreign matter. A liquid supply part that supplies a liquid to the frozen film including the foreign matter, a vibrating part that faces the frozen film, and a controller that controls the vibrating part are included. The controller controls the vibrating part to transmit a vibration to a liquid film, which includes the liquid supplied to the frozen film and a liquid generated by the thawing of the frozen film, and to reduce an energy of the vibration transmitted to the liquid film or stop the vibration according to a position of an upper surface of the frozen film under the liquid film.
