摘要
提出了一种在玻璃表面制备嵌入式亚微米金属线的方法。首先利用飞秒激光直写技术在玻璃表面烧蚀出亚微米线宽的凹槽,然后采用连续流化学镀工艺在样品表面沉积金属薄膜,再经过热处理和机械抛光,可实现玻璃表面嵌入式亚微米线宽金属结构的可控制备。将飞秒激光烧蚀的阈值效应与连续流化学镀相结合,可制备出最小线宽约为0.66 μm的金属银线。四探针法测试结果表明,制备的亚微米金属银线具有良好的导电性,其电阻率约为体积银电阻率的1.2倍。
Abstract
In this study, a method for fabricating embedded submicron metal wires on glass surfaces is demonstrated. First, grooves with submicron linewidths were ablated on glass surfaces using femtosecond laser direct writing. Then, metal films were deposited on the laser-treated glass surfaces using continuous-flow electroless plating. Subsequently, the plated samples were annealed by a thermal treatment process. Finally, an additional mechanical polishing process enabled the controllable fabrication of the embedded submicron metal wires on the glass surfaces. By combining the threshold effects of femtosecond laser ablation and continuous-flow electroless plating, metallic silver lines with a minimum linewidth of approximately 0.66 μm can be prepared. Moreover, four-probe measurement results indicate that the resistivity of the fabricated submicron metal wires is only approximately 1.2 higher than that of bulk silver, thus indicating their good electrical conductivity.
