    摘要: According to one embodiment, a mask determination method includes at least one of the in-plane error average value and the distribution of in-plane dispersions in a mask plane are measured with respect to at least one of the dimension and the optical characteristics of a mask pattern formed on a mask. Then, an illumination condition, under which a cost function representing an image performance formed on a substrate approaches a desired value when the exposure light is irradiated onto the mask and an on-substrate pattern is formed, is calculated based on at least one of the measured values. Further, whether the mask is acceptable or defective is determined based on the image performance when the on-substrate pattern is formed under the illumination condition.

    摘要: An exposure apparatus inspection mask has asymmetric diffraction grating regions for generating +1-order diffracted light and −1-order diffracted light having a different diffraction efficiency. The asymmetric diffraction grating region includes: a transparent substrate; semi-transparent phase shifter films selectively and periodically disposed on the transparent substrate at a predetermined pitch; and shade films selectively and periodically disposed on the phase shifter films at a predetermined pitch. The phase shifter films are formed to have such a thickness that the phase difference between the phase of first light passing through only the transparent substrate and the phase of second light passing through the phase shifter films and the transparent substrate is set to a value other than 180°×n (n is an integer equal to or larger than 0).

    摘要: In a model-based OPC which makes a suitable mask correction for each mask pattern using an optical image intensity simulator, a mask pattern is divided into subregions and the model of optical image intensity simulation is changed according to the contents of the pattern in each subregion. When the minimum dimensions of the mask pattern are smaller than a specific threshold value set near the exposure wavelength, the region is calculated using a high-accuracy model and the other regions are calculated using a high-speed model.
