For a wavelength of 365 nm, the electrical characteristic of Ag films was improved when the silver film was photo-sintered at larger light intensity and for longer irradiation duration. In particular, considerable reduction on the resistivity was observed on the samples irradiated having a light intensity of 300 mW/cm2 . The minimum resistivity of five.44 10-6 m (just about three occasions compared to worth of bulk silver) was obtained in the optimum photo-sintering circumstances of 300 mW/cm2 and 50 min. Related results were obtained to get a wavelength of 385 nm, even though the resistivity exhibited larger values in all samples, suggesting the shorter wavelength of UV-LED are more successful for far better electrical overall performance. The minimum resistivity of five.44 10-6 m (sheet resistance of 72.six m/sq), comparable value from Ag films photo-sintered with IPL [55], was obtained from the optimum photo-sintering circumstances (300 mW/cm2 and 50 min). Comparing to values of thermally sintered silver film (Figure five), the films irradiated with the UV-LED modules appeared to possess greater electrical conduction, no matter the wavelength. The significant modifications inside the electrical resistivity of Ag thin films according to the sintering circumstances are attributed to a RO5166017 Protocol number of reasons. Dziedzic et al. [56] suggested that when the curing temperature got higher, the mass and thickness from the conductive pillars inside the carbon/polyesterimide (PEI) composite films decreased, resulting in lower electrical resistance. Nevertheless, there was no massive difference in the thickness of Ag films depending on the curing temperature or the sintering methods (thermal and photo-sintering), although the as-pre.
