室温下通过直流磁控溅射Al2O3掺杂3%(质量分数)的ZnO靶材制备了厚度约1μm、结晶度高、表面平整光滑的ZnO∶Al透明导电薄膜.研究盐酸、王水和草酸溶液对ZnO∶Al薄膜的湿化学刻蚀行为,分析刻蚀对薄膜微观结构、光刻图案、电学和光学性能的影响.结果表明,刻蚀对薄膜的结晶取向性无影响;经盐酸、王水和草酸刻蚀后薄膜的电阻率略有增大,从7.4mΩ·cm分别增大到8.7mnΩ· cm、8.8mQ·cm和8.6mΩ·cm;透光率略有下降,从80%分别下降到76%、77%和78%.0.5%的盐酸刻蚀可以获得结构良好的陷光结构.薄膜在盐酸中刻蚀速率快,易产生浮胶;在草酸中刻蚀图案清晰,但存在残留;在王水中刻蚀图案清晰且无残留.
