Description

铜/钼膜层用蚀刻液组合物 技术领域
本发明涉及铜制程刻蚀领域,尤其涉及一种铜/钼膜层用蚀刻液组合物。
背景技术
近年来,随着显示器的需求量的增加,人们对产品的质量和画面精度也提出了更高的要求,而蚀刻的效果好坏,直接影响电路板制造工艺的好坏,进而影响显示图像的质量。随着显示器尺寸的增大,与薄膜晶体管连接的栅极线和数据线等金属配线的长度会增加,随之金属配线的电阻会增加,会产生信号延迟等问题。
目前,显示器的金属配线通常采用铜金属,相较于铝金属,铜的电阻值低,加工性能优异,铜导线的线宽不需要达到铝导线的宽度,就能提高显示器的穿透度和背光源的使用效率,因此铜导线更加适合用于高分辨面板的制作。
显示面板中铜制程图案的形成一般为:先在基板上形成铜/钼薄膜,钼能够增加铜与基板的贴附性,同时能够阻止铜在基板上的扩散;再在铜/钼薄膜上形成预定图案的光刻胶;之后,利用蚀刻液对铜/钼薄膜进行刻蚀,以形成金属线路。但是,传统的含氟蚀刻液具有腐蚀性,刻蚀效率低下,稳定性差,且对环境不友好。
