NaugaNeedles NNArrayTM

NaugaNeedles is proud to introduce a unique patent pending [1] products called NNArrayTM. NaugaNeedles offers arrays of nanoneedles that are formed on prefabricated silicon microstructures.  The technology is used to provide a method and apparatus of restoring sharp probes attached to the manipulator inside a dual beam (FIB-SEM) without a need to open up the vacuum chamber.  The NNArrayTM for in-situ restoration of probe tips saves considerable time and resources. The time required for sharpening a tungsten probe using NNArrayTM is less than 10 minutes. While the time for sharpening a tungsten probes using FIB more than 45 minutes. In addition, the tungsten probes need to be changed (by breaking the vacuum and opening the chamber) after 4 to 5 times of sharpening the probes.     
The NNArrayTM is also used for construction and application of various shapes of nanoforks inside a FIB vacuum chamber. The nanofroks are used to handle specimen without the need to weld the specimen to the probe.
Each NNArrayTM includes more than a thousand silver/gallium nanoneedles that can last several month of supply for the in-situ lift-out process. Nanoneedles are between 15 and 50 µm in length and 600 to 1000 nm in diameter.
