In a liquid processing apparatus configured to remove, from a substrate including a first film and a second film formed above the first film, the first film and the second film, a first chemical-liquid supply part supplies, to a substrate W, a first liquid for dissolving the first film, a second chemical-liquid supply part supplies a second chemical liquid for weakening the second film, and a fluid supply part serving also as an impact giving part gives a physical impact to the second film so as to break the second film and supplies a fluid for washing away debris of the broken second film. A control device controls the respective parts such that, after the second liquid has been supplied and then the fluid has been supplied from the fluid supply part, the first chemical liquid is supplied.

A modified cross-section material having a thin part and a thick part in its widthwise direction is manufactured through a plurality of roll stages. Each rolling stage comprises of a set of a convex roll and a flat roll, wherein the convex roll has a convex part. The thin part is formed in accordance with the lengthwise expansion by the convex part of the convex roll, and the thick part is formed in accordance with the lengthwise expansion by a part other than the convex part of the convex roll.

A method is provided for reducing the amount of film fragments discharged into a processing liquid circulation system during removal of films from wafers, thereby reducing the frequency of filter cleaning or filter replacement. The method includes exposing a wafer containing a film formed thereon in a process chamber of a substrate processing system to a processing liquid, where the wafer is not rotated or is rotated at a first speed and the processing liquid is discharged from the process chamber to a processing liquid circulation system. Subsequently, exposure of the wafer to the processing liquid is discontinued and the wafer is rotated at a second speed greater than the first speed to centrifugally remove fragments of the film from the wafer. Next, the wafer is exposed to the same or a different processing liquid and the processing liquid is discharged from the process chamber to a processing liquid drain.

A wafer processing apparatus prevents the reattachment of particles to wafers, such as semiconductor wafers, when processing the wafers by immersing the same held in a vertical attitude in a processing liquid and a cleaning liquid. When immersing the wafers processed by the processing liquid in the cleaning liquid contained in and overflowing a cleaning tank, a wafer holding device holding the wafers in a vertical attitude is stopped temporarily upon the immersion of lower parts of the wafers in the cleaning liquid. Consequently, particles contained in the processing liquid remaining on the wafers are dispersed in the overflowing cleaning liquid, so that the particles can be removed from the wafers and the reattachment of the particles to the wafers does not occur. When transferring the processed wafers to another processing tank or a cleaning tank, a clean gas is blown upward from below the wafers to suppress the down flow of the processing liquid remaining on the wafers in order that films formed on the wafers can be processed uniformly. This serves to improve the yield.
