    摘要: In an exposure process or etching process, an image feature amount useful for estimating a cross-sectional shape of a target evaluation pattern, process conditions for the pattern, or device characteristics of the pattern is calculated from an SEM image. The image feature amount is compared with learning data that correlates data preliminarily stored in a database, which data includes cross-sectional shapes of patterns, process conditions for the patterns, or device characteristics of the patterns, to the image feature amount calculated from the SEM image. Thereby, the cross-sectional shape of the target evaluation pattern, the process conditions of the pattern, or the device characteristics of the pattern are nondestructively calculated.

    摘要: To enable SEM-based management of a cross-sectional shape or manufacturing process parameters of a semiconductor device pattern to be measured, the association between the shape or parameters and SEM image characteristic quantities effective for estimating the shape or parameters is saved as learning data. The image characteristic quantities are collated with learning data to estimate the shape or to monitor the process parameters. Accuracy and reliability is achievable by calculating three kinds of reliability (reliability of the image characteristic quantities, reliability of estimation engines, and reliability of estimating results) based on the distribution of the image characteristic quantities and then judging whether additional learning is necessary, or selecting and adjusting image characteristic quantities and estimation engine based on the reliability.

    摘要: A method is provided for estimating a cross-sectional shape or for monitoring manufacturing process parameters of a semiconductor device pattern to be measured. In this method, in order to enable SEM-based management of the cross-sectional shape or manufacturing process parameters of the pattern to be measured, the association between the cross-sectional shape or process parameters of the pattern and SEM image characteristic quantities effective for estimating the cross-sectional shape or process parameters of the pattern, is saved as learning data, and then the image characteristic quantities that have been calculated from a SEM image of the pattern are collated with the learning data to estimate the cross-sectional shape or to monitor process parameters of the pattern. Estimation with high accuracy and reliability is achievable by calculating all or part of three kinds of reliability (reliability of the image characteristic quantities, reliability of estimation engines, and reliability of estimating results) based on the distribution of the image characteristic quantities and judging from the calculated reliability whether additional learning of the learning data is necessary, or selecting and adjusting image characteristic quantities and estimation engine based on the reliability.
