eLINE Plus: Ultra High Resolution Electron Beam Lithography, Nanoengineering and Imaging

The eLINE Plus from Raith is considered to be the optimum, widely distributed system for Research Centers and Universities that want to incorporate an Electron Beam Lithography system with an open platform for extra optional nanofabrication processes and methods in a single tool. A gas injection system for FEBIP processes, totally incorporated nanomanipulators for example, nanoprobing and a wide range of additional options complement the uncompromised lithography system architecture and allow the eLINE Plus to become the world’s most unique and universal nanoengineering EBL system.

Expandable Research Tool Concept

eLINE Plus´s modularly expandable research tool concept allow users to upgrade and adapt their system to existing trends in nanoresearch even long after the system is purchased. The eLINE Plus, by spanning beyond the “classical EBL application range”, makes way for interdisciplinary activities – across several fields of research.

The smallest electron beam size of 1.6 nm, prodived by an EBL system, indicates an indisputable prerequisite for analyzing the maximum resolution nanofabrication beyond boundaries – whether in nanolithography or other focused electron beam induced processes (FEBIP).

TwinLITH – Combining the Strengths of EBL and FIB

The perfect solution for next-generation nanofabrication is offered when a Raith electron beam lithography tool is integrated with a Raith focused ion beam system. Since the Raith systems share a software and hardware platform, it is possible to realize perfect synergy of 2D EBL resist accelerated lithography and 3D direct FIB patterning. The shared lithography architecture allows easy exchange of GDSII designs, job lists and sample holders, and thus permits efficient and advanced nanofabrication.

These two separate and complementary systems permit the working of additional nanofabrication tasks in parallel without losing time or compromising the whole benefit of either nanofabrication method. It is possible to write with two hands in a simultaneous manner and make the most of every single tool’s strengths for patterning, process development and control.
