Number techniques using excimer lasers [1]
or synchrotron radiation [2] are employed for modification of polymers. Changing a chemical structure of the surface layer under the influence of extreme ultraviolet radiation is accompanied by a significant changes in its morphology. In this work poly(methyl methacrylate) (PMMA) and polyethy- lene terephthalate (PET) was irradiated with ex- treme ultraviolet. Radiation in the range from 5 to 70 nm wavelength was produced using a laser- plasma EUV source based on a double-stream gass- puff target. Depending on a susceptibility of the samples for EUV radiation parameters, different surface structures are created. In this experiment PMMA was irradiated with EUV photons in a spec- tral range selected with aluminum filter, while PET
was irradiated directly. Effects, range and na- ture of these interactions were investigated by high- resolution scanning electron microscopy. Cross sec- tions were performed using a focused ion beam.
