X-ray Lithography

The Institute for Microstructure Technology (IMT) operates the cleanroom facility which is equipped with three LIGA beamlines to perform X-ray lithography. Each beamline is dedicated to a specific task in the LIGA-process, which are high resolution X-ray mask making (LITHO 1), deep X-ray lithography (LITHO 2) and ultra deep X-ray lithography (LITHO 3), depending of the available spectrum, which is filtered by a dedicated mirror in case of LITHO 1 and LITHO 2.
