The Whitepaper describes the state-of-the-art focused ion beam column technology and its key strengths to achieve cutting-edge application results.
Whitepaper: FIB-SEM nanofabrication (.pdf)
Learn how to benefit from resistless FIB nanofabrication and how to get access to a wide range of applications which are beyond the reach of common FIB-SEM and EBL instruments. The Whitepaper highlights typical applications that can be addressed with VELION, such as 3D nanostructures at once over mm length, FIB hard masking of large area patterns and many more.
Whitepaper: Multiple ion species for FIB with IonSelect (.pdf)
Learn how the unique IONselect technology gives you the chance to utilize light or heavy and swift or slow ions from universal ion sources. Immediate switching between different ions paves the ways for new lithography process pathways. The Whitepaper describes the innovative source technology of Raith’s nanoFIB column with IONselect and its availability of various ions for FIB nanofabrication.
Whitepaper: GaBiLi – the next generation FIB source for 2D and 3D ion imaging (.pdf)
Find out how to get high-resolution 2D and 3D images of your sample, utilizing light and heavy ions from the same source for ion microscopy.

Application Note: Ion beam lithography for Fresnel zone plate fabrication in gold on membranes (.pdf)
Fresnel zone plates are widely used as diffractive-based focusing elements in X-ray microscopy, achieving resolutions down to 25 nm. While they are typically prepared by EBL, this application note shows how the fabrication of zone plates by a dedicated FIB nanofabrication system (RAITH ionLINE) is able to significantly reduce the fabrication steps while still deliver the necessary high resolution.
Application Note: Sketch & Peel (.pdf)
A standard adhesive tape can help overcome the relatively slow patterning speed of direct FIB milling. The Application Note explains the new sketch & peel approach in detail and also investigates the change in outcome when using different ion species. Learn how simple adhesive tape can help you increase your throughput up to several orders of magnitude compared to usual FIB milling.
Application Note: Advanced gallium-free TEM lamella preparation using VELION FIB-SEM (.pdf)
High quality TEM lamellae are crucial for high-resolution TEM characterization. Using a vertical FIB column with multiple ion species for TEM sample prep yields many advantages.
