铜在醋酸介质中腐蚀行为及其缓蚀剂缓蚀行为的电化学研究

, 1990
本文利用循环伏安典线。动电位极化曲线和交流阻抗频谱方法研究了铜在醋酸系列介质中的腐蚀行为．不但研究了铜的阳极溶解过程。而且还研究了其阳极还原过程、包括氧的还原过程，并且研究了醋酸浓度．溶解氧浓度。Cl-离子和温度对此腐蚀的影响。结果表明腐蚀的阳极过程—铜的溶解不是一个可逆过程。在无水冰醋酸中受Cu(I）扩散与控制。在水落液中受传荷控制。铜表面上的膜（氧化膜、阴离子、吸附层和盐层）不致密。只是一种类似于有一定漏电性质为电介质。易被O2、H2O、Cl-和高温破坏．不能完全阻止铜的溶解和腐蚀 ...

大规模防止MEMS器件结构层材料被电化学腐蚀的方法

本发明公开了一种大规模防止MEMS器件结构层材料被电化学腐蚀的方法，该方法是利用光刻胶这种高分子材料来阻断器件的结构层材料与贵金属在HF基腐蚀液中形成原电池的电学通路，具体包括：在SiO2层的湿法腐蚀之前，在器件表面旋涂一层光刻胶，使其完全覆盖贵金属层表面。利用本发明，使光刻胶形成具有较低孔密度的致密体型高分子结构，阻断贵金属与结构层材料在HF基腐蚀液中的原电池电路，从而有效避免了结构层材料被氧化腐蚀。该方法仅在标准MEMS器件加工工艺中增加一步标准光刻步骤 ...
