Team Nanotec is clearing it’s stock on CDR50, CDR70 and CDR120 critical dimension re-entrant probes. Probes are sold on a first come first serve basis.

The TNP 30 Pt is a Platinum coated Tungsten needle probe with a tip radius of about 30 nm. The Pt coating prevents oxidation and corrosion of the tungsten. A small taper angle allows for multi-probing in close proximity.

There are many applications for the coated tungsten needle probe, like:

• electrical characterization of Integrated Circuits for failure analysis

• characterization of nano structures in research and development

• micro- and nano-manipulation

• sample preparation and positioning in cross-beam systems

• ….

To account for these manifold applications the Platinum coated TNP probe comes in different tip radii and with different shank material.

HSC (hemispherical cone) tips are an extension of our EL-HAR5 tips. Due to the defined hemispherical tip shape, the ideal application is material characterization by nano indentation (e.g. bio-medical materials, polymeres), as described by S. Belikov et al in "Theoretical modelling and implementation of elastic modulus measurement at the nanoscale using atomic force microscope" published in  Journal of Physics: Conference Series 61 (2007) 1303 - 1307.

Other applications are surface roughness and step height measurements with extended tip life, due to wear resistant coatings.

These tips are coated with either metal carbide, silicon nitride or hydrophobic carbon and are available with various tip radii. The tips can be shipped with SEM images.

The conical shaped probe will be offered as Bio-SC rack, which consists of 8 tips mounted in a frame. The probes are intended for applications where surface modifications are made to alter the chemistry of the probe, e.g. functionalisation in biological experiments. With the Bio-SC rack this can be done much more economical than with single cantilever chips.
The Bio-SC rack is offered in 2 modifications, with and without Gold coating.
