Abstract: According to an embodiment, a substrate processing method includes forming a liquid film on a substrate including a first region provided with a first film on an outermost surface thereof and a second region provided with a second film on an outermost surface thereof, the first film and the second film being different from each other in material. The method further includes forming a solidified film by solidifying the liquid film. The method further includes causing the solidified film on the first region to melt prior to the solidified film on the second region.

Abstract: According to one embodiment a substrate treatment apparatus incorporates, into a frozen film, a contaminant adhered to a substrate surface by freezing a liquid film on the surface. The apparatus includes a placement part configured to rotate the substrate, a liquid supply part configured to supply a liquid via a nozzle to the frozen film including the contaminant, a moving part configured to move the nozzle parallel to the substrate surface, and a controller configured to control a rotation of the substrate by the placement part, a supply of the liquid by the liquid supply part, and a movement of the nozzle by the moving part. The controller rotates the substrate by controlling the placement part, supplies the liquid to the frozen film by controlling the liquid supply part, and moves the nozzle from a perimeter edge vicinity to a rotation center vicinity of the substrate by controlling the moving part.

Abstract: A tobacco rod for a flavor inhaler includes a cylindrical container, and a flavor source including tobacco filled in the cylindrical container, in which the flavor source is filled in such a manner as to form voids over a longitudinal direction, and the following relationship is satisfied: S/T?17%, wherein T represents an area of all voids present in a cross-section of the flavor source orthogonal to the longitudinal direction of the cylindrical container, and S represents a total area of voids each having an area of 800000 ?m2 or more in the cross-section.

Abstract: The present invention provides a tobacco rod for a flavor inhaler, including a plurality of rod-shaped segments connected to one another, in which each of the segments includes a cylindrical container and a flavor source including tobacco filled in the cylindrical container, the flavor source being filled in such a manner as to form, over a longitudinal direction, a channel for causing a flavor component to pass therethrough, and the channels of the segments are discontinuously connected at the connecting portion.
