Tensorial Model for Photolithography Aerial Image Simulation

[摘要] In this paper, we propose to adapt the multilinear algebra tools to the tensor of Transmission Cross-Coefficients (TCC) values for aerial image simulation in order to keep the datatensor as a whole entity. This new approach implicitly extends the singular value decomposition (SVD) to tensors, that is, Higher Order SVD or TUCKER3 tensordecomposition which is used to obtain lower rank-(K1, K2, K3, K4)tensor approximation (LRTA(K1, K2, K3, K4)). This modelrequires an Alternating Least Square (ALS) process known as TUCKALS3 algorithm. The needed number of kernels is estimatedusing two adapted criteria, well known in signal processing and information theory. For runtime improvement, we use the fixedpoint algorithm to calculate only the needed eigenvectors. This new approach leads to a fast and accurate algorithm to computeaerial images.
