  • Publication number: 20240024524
    Abstract: The ultraviolet light irradiation device includes a light source section having a light emission surface emitting ultraviolet light having a wavelength band from 190 nm to 235 nm, a controller that controls lighting of the light source section, and a distance sensor that measures a separation distance from the light emission surface to an object facing the light emission surface. The controller is provided with a plurality of lighting operation modes. Each of the plurality of lighting operation modes is determined corresponding to a section defined by the separation distance, and is set such that an amount of the ultraviolet light emitted from the light source section differs from each other. The controller controls to switch the lighting operation mode based on a signal from the distance sensor.

  • Patent number: 11441101
    Abstract: A cleaning composition which can remove a layer of interest using a conventional apparatus, such as a coater, a baking furnace and a cleaning chamber, installed in semiconductor manufacturing equipment while preventing the damage or deformation of layers other than the layer of interest, such as a substrate and an interlayer insulation film; a cleaning method using the cleaning composition; and a method for producing a semiconductor employing the cleaning method. A layer of interest formed on a substrate is cleaned with a cleaning composition containing a component capable of decomposing the layer of interest and a film-forming polymer. An example of the layer of interest is a hard mask film. An example of the component is at least one of a basic compound and an acidic compound.

  • Patent number: 11355362
    Abstract: A washing method, a washing device, a storage medium, and a washing composition for enabling effective removal of a layer to be processed by decomposing or degenerating the layer to be processed at a higher temperature than conventionally. In a state where a substrate provided with a layer to be processed is heated, the substrate is supplied with vapor of a component that can decompose the layer to be processed, and thereafter the layer to be processed that has reacted with the component is removed from the substrate. As the component, a nitric acid or a sulfonic acid is preferable. As the sulfonic acid, a fluorinated alkyl sulfonic acid is preferable.

  • Patent number: 9744551
    Abstract: Disclosed is a coating apparatus capable of enhancing the film thickness uniformity. The coating apparatus includes a nozzle and a moving mechanism. The nozzle includes a storage chamber that stores a coating liquid and a slit-like flow path that is in communication with the storage chamber, and discharges the coating liquid through a discharge port formed at a front end of the flow path. The moving mechanism moves the nozzle and the substrate relatively to each other along a surface of the substrate. Also, in the flow path provided in the nozzle, flow resistance at the central portion in the longitudinal direction is larger than that at both end portions in the longitudinal direction.

  • Patent number: 8522712
    Abstract: In a template treatment of forming a film of a release agent on a treatment surface of a template, the treatment surface of the template is first cleaned. Thereafter, in a coating unit, the release agent is applied to the treatment surface of the template. The release agent on the template is then dried. Then, alcohol is applied to the release agent on the template to make the release agent adhere to the treatment surface of the template and to remove an unreacted portion of the release agent. Thereafter, the alcohol on the template is dried and removed. In this manner, a film of the release agent is formed in a predetermined film thickness on the treatment surface of the template.

  • Patent number: 8468943
    Abstract: 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.
