Precise microstructuring of indium-tin oxide thin films on glass by selective femtosecond laser ablation

Abstract: Transparent conductive oxide (TCO) thin films were removed from glass substrates using femtosecond laser pulses. Irradiating through the glass, the threshold for complete TCO ablation was much lower than for front-side irradiation. Additionally, the former method created almost rectangular crosssectional groove profiles despite the Gaussian laser beam. This indicates a non-thermal ultrafast ablation mechanism via critical carrier concentration achieved by the femtosecond pulse in the TCO at the interface. Very… Show more

“…Currently the ablation of metal films is widely used by laser radiation in such areas as semiconductor production, photo-electric devices, diffraction lattices and other hightechnology appendices [1][2][3][4][5][6][7][8][9]. In this field researches is actual the task of forming of the amplitude diffraction optical elements (DOE), and also the masking layers applied to transfer of a microrelief in a substrate is actual.…”
