PHI Quantera II Scanning XPS Microprobe

 

Introduction:

PHI Quantera II Scanning XPS Microprobe is the next generation of PHI’s highly successful product line of scanning XPS microprobe.  The Quantera II features of: a patented micro-focused scanning x-ray source, patented dual beam charge neutralization technology, a floating column ion gun for XPS sputter depth profiling, a large travel five axis precision sample stage and flexible robotic sample handling, and a fully automated internet ready instrument platform.  The Quantera-II increases the performance and productivity of these revolutionary technologies, providing the highest performance XPS system available to meet your current and future XPS needs.

BENEFITS:

  • User Friendly: Whether you are analyzing a thin polymer sheet, a large plastic lens, a steel razor blade, or electrically isolated solder bumps; the instrument set-up is the same.  Point and click at an optical image to select the analysis areas.  Then start the analysis with the dual beam neutralizer and the auto-Z functions activated to provide automatic sample alignment and charge neutralization.  There is no individual sample tuning, no concerns over sample composition and size, and no worries about walking away from the instrument and letting it automatically collect data from all your samples.

  • Thin Film Analysis: Quantera II not only provides good depth profiling analysis performance to the inorganic thin film sample, but also has the superior depth profiling performance on organic thin film samples by using the C60 ion gun.  Figure 3(a) is showing the use of floating-type Ar ion gun to perform a sputter depth profile on a Solder ball and the 3(b) is an organic thin-film depth profile using the C60 ion gun.

  • Scanning XPS Microprobe: PHI’s patented scanning x-ray source provides a scanning microprobe environment for performing micro-area XPS analysis.  An electronically raster scanned micro-focused electron beam strikes an aluminum anode creating a point source of aluminum x-rays.  The ellipsoidal shaped monochromator delivers a scannable focused beam of monochromatic aluminum x-rays to the sample surface.  When the electron beam is scanned on the aluminum anode, the x-ray beam is scanned on the sample surface.  The diameter of the x-ray beam can be adjusted from less than 7.5 μm to 400 μm in diameter.

  • Micro-Area Spectroscopy: No contaminants were visible with an optical microscope on the surface of this transparent polymer film.  A secondary electron image immediately revealed the presence of unexpected localized contaminants on the polymers surface.  Micro-area spectra obtained with a 20 μm diameter x-ray beam identified a fluorocarbon contaminant in a few minutes.
