Xact200 Twin Beam AIM System

Xact200 Twin Beam AIM System

Xact200 performs cutting-edge TEM/STEM sample preparation in line with the Semiconductor and Nanotechnology roadmap requirements for next generation physical FA and characterization.

The Xact200 is a second-generation system uniquely combines the disruptive innovative AIM technology with an integrated FE SEM column, in process real time STEM imaging capability and piezo based multi axes eucentric manipulator.

The Xact200 delivers excellent sample quality, significantly reduced turn-around times and enhanced productivity.

AIM, SELA’s proprietary Adaptive Ion Milling technology, is superior to traditional Focused Ion Beam (FIB) and Broad Ion Bean (BIB) technologies in ability to reduce lamella thickness below 15 nanometers over a large area with artifact-free quality, high precision, controlled thickness variation and high throughput.
