WebJan 17, 2024 · What is the average thickness of the native oxide growing on a typical commercially available silicon wafer? I need to get an idea of how thick the native oxide is on a silicon wafer (100)... WebTo calculate Ohms-cm using a four point probe, one needs to know the thickness of the wafer (if it is a homogeneous wafer) or the thickness of the top layer that’s being measured, to be able to calculate Ohms-cm. The four point probe technique is used to measure one single layer or one single homogeneous material.
