摘要
This paper describes the modeling approach and the implementation of a simulation algorithm for three-dimensional development processes of positive photoresists. The method is based on the cell-removal algorithm and has been incorporated into the simulator tool SOLID (Simulation of Optical Lithography in three Dimensions). For a validation of the algorithm the tool has been applied for a study on optically exposed, developed profiles of positive photoresist with reduced fidelity due to the presence of defects on the reticle. For this investigation a number of experiments were carried out using production type exposure equipment and resist material. Simulated and experimental results are compared.
