20110027727 | Substrate developing method, substrate processing method and developing solution supply nozzle - According to the present invention, an anti-reflective film formed under a resist film is removed in a photolithography process of a wafer without affecting the resist film. According to the present invention, in a photolithography process of a substrate, an anti-reflective film having solubility in the developing solution is formed and thereafter a resist film is formed. In development treatment after exposure processing, a developing solution is supplied to the substrate to develop the resist film. At an instant when the development of the resist film is finished, a second developing solution lower in concentration than the developing solution is supplied to the substrate. Only the anti-reflective film is dissolved and removed by the supply of the second developing solution. | 02-03-2011 |
20120202301 | METHOD OF FORMING MASK PATTERN - A disclosed method of forming a mask pattern includes forming a first resist film on a film to be etched, opening portions on the first resist film at a predetermined pitch, a first film on the first resist film so as to cover sidewalls of the first opening portions, a second resist film, second opening portions alternately arranged with the first opening portions on the second resist film, and a second film on the second resist film so as to cover sidewalls of the second opening portions, and removing a part of the second film so that the second film is left as first sidewall portions, a part of the first resist film using the first sidewall portions as a mask to form third opening portions, and a part of the first film while leaving the first film as second sidewall portions to form fourth opening portions. | 08-09-2012 |
20120211873 | METHOD FOR FORMING A PATTERN AND SEMICONDUCTOR DEVICE - A method for forming a pattern includes: forming a resist film on an object and patterning the formed resist film; forming a spacer film to coat the object and the resist film, and forming a concave portion surrounded by the spacer film; forming a first opening from the concave portion by etching a portion of the spacer film so that the spacer film remains beside a side wall of the resist film while exposing the object under the concave portion and the top surface of the resist film; and forming a second opening by removing the resist film. | 08-23-2012 |
20120220132 | SEMICONDUCTOR DEVICE MANUFACTURING METHOD - A semiconductor device manufacturing method includes: forming a core layer, an anti-reflection film and a photoresist layer on a layer to be etched of a substrate; trimming first line patterns of the photoresist layer; forming a first film on the first line patterns; removing the first film such that the first film is left in sidewall portions of the first line patterns of the photoresist layer; removing the photoresist layer; producing the core layer into second line patterns by etching the anti-reflection film and the core layer; forming a second film on the core layer produced into the second line patterns; removing the second film such that the second film is left in sidewall portions of the second line patterns of the core layer; and producing the layer to be etched into third line patterns by etching the layer to be etched. | 08-30-2012 |
20130209941 | METHOD OF FORMING PATTERN - A method of forming a pattern including applying a resist composition to a substrate to form a resist film, and then subjecting the resist film to exposure and development, thereby forming a first pattern containing a resist film; forming a SiO | 08-15-2013 |
20140083972 | PATTERN FORMING METHOD - Provided is a pattern forming method which includes forming fine lines and spaces in a thin film on a substrate; forming a first pattern which is a reverse pattern of a trench pattern for forming wiring by cutting the lines; and forming a second pattern which will become the trench pattern by reversing the first pattern. | 03-27-2014 |
20140094034 | PATTERN FORMING METHOD - A pattern forming method includes forming a pattern forming material film on a substrate as an etching target film, the pattern forming material film having an exposing section that has porosity upon exposure and a non-exposing section, patterning and exposing the pattern forming material film for the exposing section to have the porosity, selectively infiltrating a filling material into voids of the exposing section to reinforce the exposing section, and removing the non-exposing section of the pattern forming material film by dry etching to form a predetermined pattern. | 04-03-2014 |
20140235065 | METHOD OF MANUFACTURING SEMICONDUCTOR DEVICE AND SEMICONDUCTOR MANUFACTURING APPARATUS - Disclosed is a semiconductor device manufacturing method that manufactures a semiconductor device having a resist pattern which is excellent in roughness property and line width property. The method includes forming a film which is elastic and incompatible with a resist patterned on an object to be processed to cover the surface of the resist, and heating the object to be processed formed with the film. | 08-21-2014 |
