Abstract
A non-transitory computer readable storage medium according to an embodiment stores a mask evaluation program evaluating a mask used to manufacture an integrated circuit device. The program causes a computer to realize a convolutional neural network. The convolutional neural network output a calculated value of second data when first data is input. The first data corresponds to a circuit pattern of the mask. The second data corresponds to a pattern formed by the mask. The convolutional neural network has a filter and a weighting coefficient learned to reduce an error of the calculated value and an actual measured value of the second data by using the first data and the actual measured value of the second data.
