    • A method of making a simulation model, includes specifying a feature factor which characterizes a pattern layout of a mask pattern, specifying a control factor which affects a dimension of a resist pattern to be formed on a substrate by means of a lithography process using the mask pattern, determining a predicted dimension of the resist pattern to be formed on the substrate by means of the lithography process using the mask pattern through the use of a model based on the feature and control factors, obtaining an actual dimension of the resist pattern actually formed on the substrate by means of the lithography process using the mask pattern, and setting the feature and control factors and the predicted dimension as input layers and setting the actual dimension as an output layer to construct a neural network.
    • 一种制作仿真模型的方法包括指定表征掩模图案的图案布局的特征因子,通过使用掩模的光刻工艺指定影响待形成在抗蚀剂图案的尺寸的控制因素 通过使用基于特征和控制因子的模型通过使用掩模图案的光刻处理来确定要在基板上形成的抗蚀剂图案的预测尺寸,获得实际形成的抗蚀剂图案的实际尺寸 通过使用掩模图案的光刻工艺在衬底上,并将特征和控制因子和预测尺寸设置为输入层,并将实际尺寸设置为输出层以构建神经网络。
