Webinars EBL and metrology

In this webinar series we will cover different aspects of electron beam lithography such as relevant performance parameters, large area imaging, 1D and 2D materials, metrology and many more.

Relevant Performance Parameters for professional EBL: About Truth and Myth

In the nanofabrication market, there is a wide choice of electron beam lithography systems, each having specific strengths for specific applications. These EBL systems are typically categorized by their main specifications and performance parameters somehow representing their lithographic capabilities with respect to throughput, accuracy or resolution. In this webinar, the nature of and the interplay between these main parameters such as beam energy, beam current, beam diameter, write field size, pattern generator speed, stitching or overlay values and their relevance for a good system performance with respect to specific applications is addressed.

Nanocontacting and Device Fabrication of randomly distributed 1D and 2D materials

1D and 2D materials are attracting more and more researchers to develop future electronic devices and sensors. Such materials can be nanowires, -tubes or -whiskers, flakes or growing islands of CVD materials. Typically their distribution on the chosen substrate is random. Representing a very common EBL application, in a first step it is most important to identify and contact these nanostructures in order to connect them to the outside macroscopic world for fundamental analysis such as e.g. conductivity measurements. Alternatively or in subsequent process steps respectively, these low dimensional nanostructures need to be turned/integrated into a functional device. In this webinar, some alternative approaches for identifying, nanocontacting or integrating randomly distributed 1D and 2D materials – even in semi-automated way over large areas and by maintaining pristine surfaces – are presented.

Nanodevice Optimization by automated large Area Imaging and Metrology

Typically, nanodevice fabrication requires a few electron beam lithography exposure steps and related optimization loops in order to achieve a functional device “perfectly” matching required dimensions and quality. A common procedure is to expose a matrix of the nanostructures in many different writefields and play around with various parameters such as exposure dose or patterning strategy from one writefield to the next. Subsequently, the results need to be inspected and qualified in a dimensionality check. This may happen by subsequent acquisition of a series of SEM images for further evaluation or direct metrological measurements at the places of interest, alternatively. In this talk, various approaches for qualitative inspection and quantitative metrological measurements are presented in order to improve the nanodevice quality during the device optimization process.

Webinars VELION - A Novel FIB-SEM Nanofabrication Instrument Concept and its Applications in Nanoscale Science and Engineering

Raith has developed advanced Focused Ion Beam instrumentation over the last fifteen years with the vision that nanofabrication has special requirements that should drive the development of FIB technology. As a result, the VELION was developed to pave the path for unique applications in nanofabrication.

In this webinar series we will show you the unique capabilities for large area patterning as well as employing ion species beyond gallium to enable numerous applications in the field in nanoscale science and engineering.

Focused Ion Beams for advanced nanofabrication

The VELION is a FIB-centric FIB SEM where the ion beam is always perpendicular to the sample plane. With a side mounted FE-SEM column and a laser interferometer stage at nm accuracy more sophisticated applications become possible. The VELION takes advantage of stability, large and fully corrected fields-of-view, and laser interferometer stage. These demands and features are essential components in EBL instrumentation and have been utilized in a FIB SEM system for the first time. In this talk we will introduce the general setup of the VELION, the instrument concept in order to serve needs for advanced nanofabrication. The plasmonics and nanophotonics community has already demonstrated that there are applications whereby FIB on a Lithography platform has its advantages in delivering answers to important questions in nanoscale science and engineering.

FIB SEM applications beyond gallium and benefits of AuSi ion beams

With the appreciation that the ion’s properties can have dramatic consequences on the physical and chemical nature of the resulting nanostructures, we have extended the technology towards the stable delivery of multiple ion species selectable into a nanometer scale focused ion beam by employing a liquid metal alloy ion source. This LMAIS provides single and multiple charged ion species of different masses, resulting in significantly different interaction mechanisms. In this talk we also discuss the motivation behind applications employing non-Gallium species, such as Silicon, Gold, Germanium and their benefits and present results of Au and Si ion beam nanofabrication.

Advanced FIB patterning and Large Area applications

Ion beam nanofabrication has proven unique strengths by numerous applications in R&D prototyping. It helps to achieve scientific results by in-situ optimization of patterning parameters for 2D and 3D structures. Traditional ion beam-based instruments lack large, corrected fields-of-view and laser interferometer stages, which are essential components in EBL instrumentation and are mandatory for accurate ion beam nanofabrication. Here we present FIB patterning of large photonic devices like extended photonic crystals and mm-long waveguides. To overcome FIB milling related patterning artifacts like edge effects at stitch field boundaries, advanced strategies have been developed. Sophisticated continuous stage movement modes as FBMS (Fixed Beam Moving Stage) for extended continuous trench milling and MBMS (Modulated Beam Moving Stage) for stitch free patterning of periodic elements are demonstrated as well with the help of real time SEM live imaging movies of ion beam milling employing these modes. Furthermore, we present examples of advanced FIB nanofabrication by making use of the outstanding long term stability of the nanoFIB column and accuracy of the laser interferometer stage.
