ATEC-NC

Advanced Tip at the End of the Cantilever™ Non-Contact/Tapping Mode

NANOSENSORS™ AdvancedTEC™ NC AFM tips are designed for non-contact or tapping mode imaging. They feature a tetrahedral tip that protrudes from the very end of the cantilever. This unique feature allows precise positioning and makes the AdvancedTEC™ the only AFM scanning probe in the world that offers REAL TIP VISIBILITY FROM TOP, even when the probe is tilted due to its mounting onto the AFM head. This feature makes them the premium choice for all applications where the tip has to be placed exactly on the point of interest and/or has to be visible (e.g. Nanomanipulation).

Due to their very small half cone angles the tips of the AdvancedTEC™ Series show great performance on samples that have a small pattern size combined with steep sample features.

The probe offers unique features:

  • real tip visibility from top
  • typical tip radius of curvature better than 10 nm
  • tip height 15 - 20 µm
  • monolithic silicon
  • highly doped silicon to dissipate static charge
  • chemically inert
  • high mechanical Q-factor for high sensitivity

Special handling information for NANOSENSORS™ AdvancedTEC probes

Due to their unique geometry the tips of the AdvancedTEC probes are more susceptible to tip damage by electrostatic discharge (ESD) than other Silicon-SPM-Probes.

Electric fields near the probe chip may lead to field evaporation which can blunt the tip apex of the probe tip. Therefore the NANOSENSORS™ AdvancedTEC probes are shipped in specially designed ESD-safe chip carriers.

NANOSENSORS™ recommends to their customers to take appropriate precautions to avoid tip damage due to electrostatic discharge when handling the probes. This can for example be done by using anti-electrostatic mats, wrist bands and tweezers.
