Abstract

In this paper, we analyze why SOI wafers appear as they do to the naked eye. We show how a thickness variation as small as ten Angstroms can cause a readily discernible color change, and why this optical effect is much stronger in a thinned SOI wafer than in an oxide-coated wafer or in thick SOI wafers.<>
键合SOI晶圆颜色变化分析
在本文中,我们分析了为什么SOI晶圆呈现为肉眼所见的样子。我们展示了小至10埃的厚度变化如何引起易于识别的颜色变化,以及为什么这种光学效应在薄SOI晶圆中比在氧化涂层晶圆或厚SOI晶圆中强得多。
