摘要： 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.

摘要： According to one embodiment, an imprint template manufacturing apparatus includes a support unit, a vaporization unit, and an adhesion preventing plate. The support unit supports a template that includes a base having a main surface, and a convex portion provided on the main surface and having an end surface. A concavo-convex pattern to be pressed against a liquid material to be transferred is formed on the end surface. The support unit supports the template with the convex portion facing downward. The vaporization unit is located below the template on the support unit and configured to vaporize a liquid-repellent material. The adhesion preventing plate is located below the template on the support unit and configured to allow the liquid-repellent material vaporized to adhere to the side surface of the convex portion of the template and to prevent it from adhering to the concavo-convex pattern.

摘要： A substrate processing apparatus according to an embodiment of the present disclosure includes: a stage; a plurality of holders configured to hold a substrate; a liquid supply configured to supply a liquid to a surface of the substrate opposite to the stage; a cooler configured to supply a cooling gas to a space between the stage and the substrate; a mover configured to change a distance between the stage and the substrate; and a controller configured to control the cooler and the mover. The controller performs a cooling process that at least includes a supercooling process and a freezing process (solid-liquid phase), and a thawing process after the cooling process. In the cooling process, the controller controls the mover to set the distance to a first distance, and in the thawing process, the controller controls the mover to set the distance to a second distance longer than the first distance.

摘要： 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 side, a detector configured to detect a state of the liquid on the surface of the substrate, and a controller controlling at least one of 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, obtains a temperature of the liquid in the supercooled state at a start of freezing, and is configured to calculate a removal ratio of a contamination.

摘要： According to one embodiment, an imprint template manufacturing apparatus includes: a stage that support a template having a convex portion where a concavo-convex pattern is formed; a supply head that supplies a liquid-repellent material in liquid form to the template on the stage; a moving mechanism that moves the stage and the supply head relatively in a direction along the stage; and a controller that controls the supply head and the moving mechanism such that the supply head applies the liquid-repellent material to at least a side surface of the convex portion so as to avoid the concavo-convex pattern. The liquid-repellent material contains a liquid-repellent component and a non-liquid-repellent component that react with the surface of the template, a volatile solvent that dissolves the liquid-repellent component, and a fluorine-based volatile solvent that dissolves the non-liquid-repellent component.

摘要： According to one embodiment, a template for imprint includes a base, a convex portion, and a liquid-repellent layer. The base has a main surface. The convex portion is provided on the main surface. The convex portion has an end surface on a side opposite to the main surface, and a concavo-convex pattern to be pressed against a liquid material to be transferred is formed on the end surface. The liquid-repellent layer is formed on at least the side surface of the convex portion so as to avoid the concavo-convex pattern. The liquid-repellent layer repels the liquid material to be transferred.
