Description
技术领域
本发明涉及一种在其它材料存在下选择性地蚀刻氮化钛和/或光致抗蚀剂蚀刻残留物的组合物和方法。
背景技术
光致抗蚀剂掩模常在半导体行业中用于对如半导体或电介质的材料进行图案化。在一种应用中,光致抗蚀剂掩模用于双镶嵌工艺,以在微电子装置的后端金属化中形成互连件。双镶嵌工艺涉及在覆盖金属导体层(如铜层)的低k介电层上形成光致抗蚀剂掩模。随后根据光致抗蚀剂掩模蚀刻低k介电层,以形成暴露金属导体层的通孔和/或沟槽。通孔和沟槽,通常称为双镶嵌结构,通常使用两个光刻步骤来定义。随后,在将导电材料沉积至通孔和/或沟槽中以形成互连件之前,从低k介电层去除光致抗蚀剂掩模。
随着微电子装置的尺寸减小,达成通孔和沟槽的临界尺寸变得更困难。因此,使用金属硬掩模提供更好的通孔和沟槽轮廓控制。金属硬掩模可由钛或氮化钛制成,并且在形成双镶嵌结构的通孔和/或沟槽后,通过湿式蚀刻工艺去除。至关重要的是,湿式蚀刻工艺使用的去除化学试剂有效去除金属硬掩模和/或光致抗蚀剂蚀刻残留物,而不影响下方低k介电材料。换句话说,相对于低k介电层,去除化学试剂需要对金属硬掩模具有高度选择性。
因此,需要改良的组合物,以相对于低k介电层选择性地去除硬掩模材料以及存在的铜或氧化铝,而不损害硬掩模的蚀刻速率。
