Electron Beam Lithography with the optics design and powerful patterning engine for the SEM column, the system offers EBL workhorse capabilities. This enables sophisticated applications in nano electronics, physics, and photonics, and combines with FIB nanofabrication in one instrument. VELION  offers the unique opportunity of complementary advanced lithography with both ion and electron beams in a single dedicated nanofabrication system.

Benefits of SEM column support for FIB processes

The field emission SEM column significantly expands the capabilities of VELION. VELION helps to provide all the required capabilities of a FIB tool for TEM, APT or other sample preparation.

The X-section analysis is employed for high resolution imaging of FIB X-sectional cuts.

The process checks helps in the inspection of all features created by the ion beam. Given the direct patterning techniques of FIB, it is possible to check results and optimize parameters in an in-situ closed-loop approach for very efficient process development
