摘要: 电化学刻蚀使用腐蚀性小的电解质溶液,且溶液可使用周期长,是一种环境友好的加工工艺. 本文采用聚丙烯酰胺水凝胶(PAG)作为软印章,辅以优化工艺,将电化学湿印章技术(E-WETS)的加工精度从几十微米提高到了200纳米. 将新配制的聚丙烯酰胺水凝胶浇注在具有纳米结构的软模板表面,固化后脱模并保存于0.2 mol·L-1 KCl溶液中,在合适电位和压力下,对硅片表面金膜进行电化学湿法刻蚀,分别研究了聚丙烯酰胺水凝胶的聚合条件、电化学加工电位以及水凝胶表面压力对加工结果的影响. 实验表明,在最优条件下可加工出直径为200纳米的特征点阵结构,且该方法具有较好的可靠性和稳定性.

Abstract: The fabrication resolution of electrochemical wet stamping (E-WETS) was enhanced to several hundred nanometers from several ten micrometers by using polycarylamide gel (PAG) as soft stamps and through optimized processes. The PAG stamp was cured on a nanopatterned soft mold and soaked with 0.2 mol·L-1 KCl solution, then contacted with a silicon wafer with gold film and applied with electric field. And the gold nanopatterns were achieved by the selective anodic dissolving, the diameter of fabricated gold spot was around 200 nm. The parameters which affected the fabrication processes have been discussed in detail.
