  • Publication number: 20180157167
    Abstract: A manufacturing method of a photomask according to the embodiment sets an exposure condition applied when a resist is formed into a three-dimensional target shape by using a photomask including a plurality of light-shielding areas. Subsequently, the method sets a hypothetical target shape obtained by correcting a target shape based on a development characteristic of the resist for the exposure condition. Subsequently, the method creates a pattern of the photomask corresponding to the hypothetical target shape. Subsequently, the method simulates a prediction shape of the resist when the pattern is used. Subsequently, the method calculates a cost function related to an error between the prediction shape and the hypothetical target shape. Subsequently, the method adjusts the pattern based on a result of the calculation of the cost function.
