摘要:
The present invention provides a chemical-liquid mixing method and a chemical-liquid mixing apparatus capable of sufficiently generating a peroxomonosulfuric acid that is effective in removing a resist from a substrate, when a sulfuric acid and a hydrogen peroxide solution are mixed with each other. At first, an inner tank 10 is filled up with a sulfuric acid and the sulfuric acid overflowing from the inner tank 10 is allowed to flow into an outer tank 12. Then, a hydrogen peroxide solution is supplied into the inner tank 10 and the hydrogen peroxide solution is allowed to flow into the outer tank 12 whereby the two kinds of liquids of the hydrogen peroxide solution and the sulfuric acid are stored in the outer tank 12. Simultaneously when the hydrogen peroxide solution flows into the outer tank 12, a return pump 16 is activated.

The present invention provides a substrate processing apparatus for processing substrates by immersing the substrates in a processing liquid. This substrate processing apparatus includes a processing tank having a pair of side walls arranged to be opposed to each other; and a pair of processing-liquid supply mechanisms provided respectively corresponding to the pair of side walls. The pair of processing-liquid supply mechanisms are respectively configured for supplying the processing liquid toward a central portion of the processing tank in the width direction connecting the pair of side walls, thereby to create a rising flow of the processing liquid in a central area in the width direction of the processing tank. Each inner wall face of the pair of side walls includes a main body, a projecting portion located above the main body, and a discharge guide portion located uppermost and providing a discharge port configured for allowing the processing liquid to overflow. The discharge guide portion is inclined upward, opposite to the central portion in the width direction. The projecting portion includes an inner end portion located nearer to the central portion in the width direction, as compared with the main body and discharge guide portion.

A substrate cleaning method can uniformly removing particles from substrates at a high removing efficiency. The substrate cleaning method includes the steps of immersing substrates W in a cleaning liquid in a cleaning tank 12, and generating ultrasonic waves in the cleaning liquid contained in the cleaning tank. A region in the cleaning tank toward which the cleaning liquid is supplied is varied with respect to a vertical level in the step of generating ultrasonic waves in the cleaning liquid while the cleaning liquid is being supplied into the cleaning tank.

The present invention provides a method for applying an application liquid between a template and a substrate, and transferring the transfer pattern onto the application liquid. The template is inclinedly arranged with respect to the substrate in a manner that a first distance between a first end portion of the template and the substrate is a distance that causes a capillary action of the application liquid to occur, and a second distance between a second end portion of the template that opposes the first end portion and the substrate is a distance that does not cause the capillary action of the application liquid to occur. Thereafter, the application liquid is supplied from an outer side of the first end portion to the first end portion. Thereafter, the second end portion and the substrate are relatively moved so that the second distance becomes equal to the first distance.

There is provided a substrate processing method with the use of plural kinds of liquids, capable of, after a process to a substrate by using a process liquid, rapidly and more reliably substituting the process liquid remaining on the substrate with a liquid to be subsequently used. The substrate processing method comprises: processing a substrate W by a process liquid; and supplying a substitute liquid onto the substrate and substituting the process liquid remaining on the substrate with the substitute liquid. The substitute liquid used in the substituting step has a surface tension that is smaller than a surface tension of the water, and a density that is equal to a density of the process liquid.
