Residual layer thickness in nanoimprint: Experiments and coarse-grain simulation
A refined coarse-grain method for simultaneous calculation of the resist viscous flow in nanoimprint lithography and the stamp/substrate deformation is presented. The method has been realized in an effective simulation tool for the verification of stamp structures on standard personal computers, by using the GDS data of the stamp design. From the presented comparison of calculated and experimental results, it can be concluded that the coarse-grain modeling allows predicting the residual layer thickness with accuracy better than 10%.
