FIB-SEM for FIB-centric nanofabrication

FIB centric lithography architcture and laser interferometer stage supported by a tailored SEM column

VELION is a novel FIB-SEM instrument in which FIB nanofabrication has matured into the standard technique for fabricating three dimensional and high resolution nanostructures, such as plasmonic devices, nano-fluidics, localized implantation and functionalization.

With its unique set-up of a vertical FIB-column and attached SEM, in combination with Raith’s laser interferometer stage and mature lithography technology, VELION truly defines FIB nanofabrication as the priority technique. The dedicated system architecture ensures unrivaled stability, accuracy, and automation. Even the most complex structures can be fabricated with highest precision, completely unattended over many hours.

Four modes. Two beams. One system.

VELION offers unique capabilities for advanced FIB nanofabrication while also allowing sample preparation, process control, and entry level e-beam lithography - all in one tool!

FIB Nanofabrication

Benefit from achieving results faster by eliminating time-consuming and yield-limiting steps in the lithography-process like etching of new and challenging materials. Direct milling and etching are possible for the creation of 3D structures, even on topographic samples and distributed over large areas.

Sample Preparation

Prepare your TEM samples with FIB milling and SEM live control in-situ. Gas injection systems, nano probers, and accurate end-point control enable various sample preparation applications.

Process control

Check your process development and results in-situ. With advanced stage setups, high-resolution SEM, and automated metrology, process control can be performed directly for fast parameter optimization.

E-Beam Lithography

Exploit the unlimited opportunities of combined FIB and SEM in a single tool. Applying the SEM to basic EBL processes is also possible thanks to features including sophisticated parameter control, automatic scans, and proximity effect correction.
