1. 平整度：抛光之后,在对硅片检测时关注的平整度(Flatness)方面的参数为TIR与STIR,而这两个参数都是以硅片的背表面为参考平面,即认为硅片的背面为理想的平面,但实际的硅片背表面是高低不平的,故需引入另一个参数:纳米形貌(nanotopography)来表征硅片的几何特性 [5].

2. 实音：5.实音(flatness) 亦称重浊音或绝对浊音,音调较浊音更高、音响更弱、振动持续时间更短的非乐音,当叩击肌肉、实质脏器如心或肝时即为实音. 在病理状态下,见于大量胸腔积液或肺实变等.

3. 平坦度：利用ELID钻石磨轮研磨直径300-400mm之矽晶圆,可获得所期望的表面粗度与平坦度(flatness)其研磨结果则视电流、电压、磨轮转速、材质、磨粒粗细、进给率及工作台转速而决定.
