Surface chemical analysis. X-ray photoelectron spectroscopy. Measurement of silicon oxide thicknessWhat is this standard about? This document specifies several methods for measuring the oxide thickness at the surfaces of (100) and (111) silicon wafers as an equivalent thickness of silicon dioxide when measured using X ray photoelectron spectroscopy. It is only applicable to flat, polished samples and for instruments that incorporate an Al or Mg X ray source, a sample stage that permits defined photoelectron emission angles and a spectrometer with
