Nanoprobing SEM Solution Package
Intuitive in situ low current electrical measurements. Characterize your nanoscale samples in the vacuum chamber of an electron microscope, at the time of their observation.
The Imina Technologies package PN14-4B-V is a unique solution for nanomanipulation and characterization of electrical devices and advanced materials at the nanometer scale.
The solution embeds four miBotTM —our famously easy-to-use and versatile piezoactuated micro robots— allowing you to independently position the probes over millimeter scale samples with a resolution down to the nanometer.
Electrical characterization of nanostructures
Specifically designed for low current measurements, leakage currents can be as low as 100 fA/V. Electrical characterization of nanostructures can be carried out with third party signal analyzers through the shielded cabling, featuring an excellent signal-to-noise ratio.
A set of adapters is provided with the package and enables to retrofit virtually any SEM, even those with a small chamber. In fact, with a diameter of 10 cm and a flat design, the circular robot platform gets directly mounted on the SEM sample translation stage. Installation and removal only take a few minutes and don’t require to permanently modify the hamber of your microscope.
An aperture centered on the robot platform fits various types of SEM stubs, letting you observe the specimen just like you are used to.
- Faster experiments. Observe, prepare and characterize your samples at once.
- Versatile and precise instruments. Electrical measurements and mechanical manipulation at the nanometer scale.
- Hassle-free probe positioning. Instantly adjust the orientation to any sample geometries.
- High mechanical stability. Move without vibration and maintain steady electrical contacts.
- Extend the capabilities of your SEM. Retrofit even small chambers without permanent modifications.
- Four point probing
- I-V / C-V measurements
- Resistivity measurements
- Sample preparation
