Abstract

Official abstract text for this publication.

Systems and methods for performing X-ray Photoelectron Spectroscopy (XPS) measurements in a semiconductor environment are disclosed. A reference element peak is selected and tracked as part of the measurement process. Peak shift of the reference element peak, in electron volts (eV) is tracked and applied to other portions of acquired spectrum to compensate for the shift, which results from surface charge fluctuation.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for performing measurements with an X-ray photoelectron spectroscopy measurement tool, comprising: irradiating a semiconductor substrate with X-ray energy; detecting emitted electrons from the semiconductor substrate; selecting a reference element peak based on the detected emitted electrons; recording an initial location for the reference element peak; computing a shift in location for the reference element peak; and applying a correction t…
