SEM sample preparation

Sample preparation for SEM

We have different equipment for SEM sample preparation such as:

Precission Etching Coating System (PECS™)

The PECS™ is a unique ion beam based etching and sputter coating system producing exceptionally large, clean, viewable areas of specimens for Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM) and Light Microscope (LM) applications.

- Etching and coating in the same vacuum chamber.
- Three Penning ion guns with miniature rare earth magnets
- Ion Beam Energy: from 1keV to 10 keV.
- Etched area: from 7mm to 10 mm.
- Coating area: uniform over a 25 mm diameter..
- Holders: min. 25 mm, compatible with FESEM Merlin .
- Holders inclination: 0-90º.
- TEM adapters for side-entry TEM or SEM holders.
- Target: 2 standard targets, Carbon and Chromiun with 2 others available: Gold and Platinium.
- Film thickness monitor for accurate control of film thickness.
- Dry pumping system: final preassure less than 6,8E-4 Pa.

   

This equipment has been 50% confinanced by the “Fons de desenvolupament regional en el marc operatiu FEDER de Catalunya 2007”- 2013.
