Description
技术领域
本申请涉及半导体金属配线技术领域,尤其涉及金属配线蚀刻的技术领域,具体涉及一种蚀刻钼/铜/钼或钼合金/铜/钼合金三层金属配线结构的蚀刻液组合物及其应用。
背景技术
半导体阵列基板上形成金属配线的过程通常包括:溅镀(Sputter)成膜工艺,光刻胶或光致抗蚀剂涂布和显影工艺,形成金属配线的湿蚀刻工艺以及金属配线图案化后的去除不需要的光刻胶或光致抗蚀剂剥离工艺。
对于不同的金属配线结构,金属配线上下层结构,以及不同的阵列基板制作工艺,对蚀刻液的蚀刻特性要求也会不一样。当金属配线下方一层为氧化物半导体活性层时,金属配线的湿蚀刻不仅要保持较好的蚀刻特性,而且要尽量减少蚀刻液对氧化物半导体的蚀刻,从而保持活性层较好的电性结构,保证面板的信赖性,因此基于氧化物半导体的蚀刻液体系通常为无氟蚀刻液体系。
目前的基于氧化物半导体技术的源漏极通常为三层金属结构,包括钼/铜/钼和钼合金/铜/钼合金金属叠层结构,无氟蚀刻液体系中,若要满足对三层金属的一步湿刻蚀需求,只能增加刻蚀液中的双氧水含量至20-30wt%。然而由于双氧水含量较高,蚀刻过程中蚀刻液中的双氧水不稳定且浓度下降较快,进而导致当蚀刻液中铜离子浓度较小时,就不能保持刻蚀的均一性和稳定性,导致蚀刻液的寿命大大降低(约2000ppm,即蚀刻液中铜离子浓度达到约2000ppm时,此批次刻蚀液已经不能使用,需换新的蚀刻液)。当蚀刻液能够保证蚀刻均一性和稳定性,且能含有的最大铜离子浓度的时候,我们称此最大铜离子浓度为刻蚀液的寿命。
发明内容
