Estimation of exposure parameters of chosen e-beam resists using variable shaped e-beam pattern generator

In this article we present results from lithography experiments on PMMA (positive tone), and HSQ Fox-12 and SU-8 (negative tone) resists carried out on the ZBA variable shaped e-beam pattern generators. In order to obtain the necessary information needed for the optimization of the exposure control Point Spread Function PSF, several lithography tests are mentioned. The carried out measurements and analysis of the results help us in obtaining important information about the resists and exposure processes and enable us to practically verify the suggested methods of parameters extraction for a reliable exposure model.
