X-ray Photoelectron Spectroscopy (XPS) is a quantitative spectroscopic technique that measures the elemental composition, empirical formula, chemical state and electronic state of the elements that exist within the surface (1-12 nm) of any material.  XPS is also known as Electron Spectroscopy for Chemical Analysis (ESCA).

Global uses for XPS include production control, materials development, quality control, problem solving, failure analysis, and reverse engineering. XPS produces elemental composition analysis, chemical state information, line profiles, depth profiles and non-destructive angle resolved chemistry profiles.

Strengths and Advantages of XPS:

    • Complete unknown – chemistry and thickness
    • Chemical state information (eg Si vs SiOx)
    • Reliable quantification –  greater than 95% accuracy
    • Analyzes insulators and conductors
    • Elemental analysis – all elements (except H)

 

Routine Analysis:

    • Surface contamination, corrosion, discoloration
    • Chemical state information
    • Chemistry information down to 12 nm

 

Advanced Analysis:

    • Chemical depth profile down to 2,000 nm
    • Non-destructive chemistry versus depth from 1-12 nm
    • Surface uniformity of chemical states
    • Quality control with greater than 95% accuracy
