摘要： According to one embodiment, a monitor pattern is previously exposed together with a device pattern on a resist film, the monitor pattern is developed in a first development condition and a fault occurrence risk is quantified based on a check image. At this time, the range of a second development condition in which the number of faults becomes less than or equal to a permissible value with respect to the quantified fault occurrence risk is determined based on the relationship between fault occurrence risk information and the number of faults. Then, a third development condition in which the pattern dimension becomes a desired value in the second development condition is determined and the device pattern is developed in the thus determined third development condition.

摘要： According to the substrate processing method in the embodiments, as a mask substrate used for forming an EUV mask, a mask substrate in which a first film having a first hydrophilicity is formed on one main surface and a resist is applied to another main surface is exposed from a side of the resist. Then, a hydrophilic treatment is performed on a surface of the first film to make the surface of the first film have a second hydrophilicity larger than the first hydrophilicity. Then, a development treatment of the resist is performed with respect to the mask substrate in which the hydrophilic treatment is performed on the surface of the first film to have the second hydrophilicity.

摘要： A development method according to an embodiment includes exposing a photosensitive film formed on a substrate at a predetermined exposure amount, carrying out a first development process that develops the exposed photosensitive film at a predetermined first development condition so as to leave the photosensitive film, obtaining a sensitivity information of the photosensitive film from a film thickness reduction of the photosensitive film developed by the first development process and the exposure amount, predicting pattern dimensions of multiple types of patterns to be formed when a second development process is carried out following the first development process from the sensitivity information, and determining a first acceptable range of a development condition in the second development process, determining a second acceptable range of the development condition in the second development process from the first acceptable range and a variation amount of the pattern dimension after the development process between the multiple types of patterns and determining a second development condition in the second development process so as to satisfy both of the first and second acceptable ranges.
