Latest Patents

Dan Hung holds a patent titled "Method of modeling e-beam photomask manufacturing process using image-based artificial neural networks." This patent describes a groundbreaking approach where an image-based Artificial Neural Network (ANN) is utilized for photomask modeling. The ANN can self-construct an internal representation of the photomask manufacturing process, which allows for a modeling process that is not constrained by the limitations of existing mathematical and statistical tools. This innovation significantly reduces or eliminates the effort required from model-builders, which can often be tedious and costly. The ANN model requires mask layout data to be converted into image pixel form. During the ANN training phase, a first circuit image and its existing SEM image are modeled through multiple layers of convolution and rectification to extract the salient features of the transformed image. In the testing phase, a second circuit image and its existing SEM image are compared to ensure that the difference is smaller than a predetermined requirement. The satisfactory second circuit image is then converted back from pixel form to circuit layout data for photomask writing.
