摘要
通过对腐蚀溶液的优化,获得了一种刻蚀效果良好的锆钛酸铅(PZT)薄膜的腐蚀溶液配方。文中所采用的PZT薄膜是通过溶胶!凝胶(sol-gel)法获得的,在研究腐蚀溶液组分、温度以及浓度对腐蚀速率影响的基础上,成功获得了PZT薄膜微图形化的湿法腐蚀工艺。通过实验研究,获得了横向和纵向腐蚀速率随温度和浓度变化曲线,侧蚀比(横比纵)小于1:1.07,且图形表面无残留物。
A wet- chemical eroding process of PZT thin films is reported. PZT films are prepared by the means of sol-gel methods. The influence of the solution compositions, temperatures and the concentrations on the eroding rate is studied. The patterning technique of PZT thin films is successfully obtained using the wet- chemical eroding. After researching, the relationship curves of the transverse and vertical eroding ratio are obtained, the ratio of transverse/vertical is less than 1：1.07, and no residues is on the pattern.
