摘要： A pattern estimating method, wherein during exposure for forming the device pattern, a latent image of a monitor pattern which has the same pitch as an L/S pattern as the device pattern and has a narrower line width than the L/S pattern is formed in a mark area, after developing the device pattern, probing light is applied from a monitor head to the monitor pattern, and under the conditions for preventing generation of diffracted light of first-order or more, the intensity of zero-order light reflected from the monitor pattern is detected, so that the size of the device pattern is estimated on the basis of the prestored relationship between the device pattern size and the zero-order diffracted light intensity.

摘要： This invention discloses a method to form a resist pattern on a to-be-processed substrate by immersion exposure. A resist film is formed on the central portion of the upper surface of the to-be-processed substrate, on a bevel portion of the upper surface, which is obtained by chamfering the peripheral portion of the to-be-processed substrate, and on the end portion of the to-be-processed substrate. Pattern exposure for forming the latent image of a desired pattern on the resist film is executed while a liquid whose refractive index is higher than that of air exists between the resist film and a constituent element of a projection optical system of an exposure apparatus, which is nearest to the to-be-processed substrate. The resist film formed on the end portion of the to-be-processed substrate is removed by supplying a rinse solution to the end portion of the to-be-processed substrate after executing pattern exposure.

摘要： Wavelength dispersion of intensity of light reflected from an evaluation object is measured. A complex refractive index of a substance forming the evaluation object and the environment are prepared. Virtual component ratios comprising a mixture ratio of the substances forming the evaluation object and the environment are prepared. Reflectance wavelength dispersions to the virtual component ratios are calculated. Similar reflectance wavelength dispersions having a small difference with the measured wavelength dispersion are extracted from the reflectance wavelength dispersions. Weighted average to the virtual component ratios used for calculating the similar reflectance wavelength dispersions are calculated to obtain a component ratio of the substance forming the evaluation object and the environment so that weighting is larger when the difference is smaller. A structure of the evaluation object is determined from the calculated component ratio.
