Abstract

A novel technique, named as "Enhanced-ICP", for a better etch process, has been proposed. Here, we report an improved result of the E-ICP. A photo-resist etch uniformity of below 1% within 10 cm in diameter has been accomplished with improved plasma density and the low electron temperature of 1 eV.

改进的E-ICP(增强电感耦合等离子体)刻蚀技术
提出了一种新的技术,称为“增强型icp”,用于更好的蚀刻工艺。在这里,我们报告了E-ICP的改进结果。在提高等离子体密度和1 eV的低电子温度下,在直径10 cm内实现了小于1%的光阻蚀刻均匀性。
