Abstract

We have developed a three-dimensional simulation algorithm based on fast marching method that mimics the etching behavior of chalcogenide photoresists, especially for maskless interference lithography. This lithography exposure is characterized by continuous variation of the exposure intensity inside the photoresist, without step like variation. Furthermore, the chalcogenide photoresist has a “gray-scale” behavior, without definite threshold. The resulting etching process is very sensitive to exposure dose and etching time. The optimal relations between these parameters are determined both theoretically and experimentally. A very good agreement between calculation and experimental results is shown, opening the door to complex nanostructures engineering.

Group I: Under exposure; non-stable etching process. The samples were used in the calibration of the simulation software. Group II: Stable etching process. The samples were used in the calibration of the simulation software. Group III: Stable etching process. These samples were added after calibration in order to validate the prediction of the stability zone.
