摘要
Variations in the etch depth and refractive index of polymethylmethacrylate (PMMA) films of different molecular weights after synchrotron radiation (SR) irradiation are investigated. Reduction of the PMMA film molecular weight, density and thickness am observed after SR irradiation. The amount of film thickness loss depends on not only initial molecular weight but also film density. The PMMA density difference at the start of SR exposure affects the etch depth after SR ablation.
