    2010-7-28In this article, the authors focus on the profiles formed by high-aspect-ratio deep Si etching with SF 6 / O 2 plasma mixtures. One of the most serious problems for deep Si etching processes is lateral etching in the upper regions of sidewalls. This lateral etching seems to depend on time (or etched depth) rather than aspect ratio (depth/width). Reducing the SF 6: O 2Cited by: 10
