In addition, it discusses three approximation models to represent the partially coherent imaging systems, such as the Fourier series expansion model, the Singular Value Decomposition (SVD) model, and the average coherent approximation model. Proximity optical lithography is relatively simple, as it requires no image formation between the mask and the resist.
