The CAMECA SIMS 4550 is the benchmark quadrupole SIMS with top performances in depth
profiling.
The key points ensuring its success are:
Reference performances in high depth resolution analysis. This derives mainly from:
- Oxygen and cesium Floating Low energy Ion Gun technology (FLIG),
exceeding
by far the performance of conventional or extraction floating ion
columns
used in other conventional SIMS. The performance in cesium beam have
been impressively improved with the adaptation of the CAMECA Microbeam
high brightness ion source, now common on all our SIMS range.
- A total flexibility concerning the primary ion angle of incidence, even in unattended chained analysis.
- A low field of extraction of the quadrupole analyzer facilitating the use of low energy primary ions.
Reference performances in automation and reproducibility for metrology, deriving mainly from:
- a superior redesign of the quadrupole analyzer optics (extraction, transfer, gating, post-acceleration),
- a user-friendly chain analysis software and a renowned ease of use of
the instrument, reducing the need for highly-trained operators,
- ultra stable ion sources and electronics for unattended overnight measurements.
Easy insulator analysis thanks to:
- the low extraction field of the quadrupole,
- a low energy electron flood gun for charge compensation,
- unique OCE (Optical Conductivity Enhancement) for SiGe analysis.
Finally, the unique Checkerboard
capability allows the operator to check the validity of the results, remove
artifacts from sample inhomogeneity or dusts, without having to re-run the
analysis. This adds greatly to the throughput of the instrument, reproducibility and reliability of the results.

The SIMS 4550 can be delivered in different configurations.
The instrument shown on the left
is optimized for III-V semiconductors. It is equipped with the TWISTER
chamber for multiple 3-inch wafer or small sample loading and storage, a high energy cesium
gun at grazing incidence (for fast etching of several µm without rugosity
development) and a FLIG cesium gun for ultra high depth resolution analysis.
