About Us



XENOS Semiconductor Technologies GmbH was founded in 2001 and develops tools, processes and services for semiconductor and nano technology, especially electron or focused ion beam lithography. The product portfolio ranges from add-on writers that retrofit Scanning Electron Microscopes (from USB 10 MHz system to dedicated high speed writer electronics) to fully equipped FIB and EBL systems.

XENOS CEO Stefan Straehle received an industrial education in electronics and worked in the field of quality management, electronics and microcontroller development and test systems for the automotive industry. He then studied Physics at the University of Tübingen achieving a Diploma thesis on "Silylation for Electron Beam Lithography" and a Ph.D thesis on “Low Energy Electron Beam Lithography” in the group of Prof. Dr. Dieter Kern. Stefan Straehle has a profound knowledge of e-beam technology and lithography, as well as state-of-the-art analog and digital electronics, digital signal processors and complex programmable logic (FPGAs).

XENOS' main office and SEM laboratory is located in Kusterdingen, Germany. XENOS uses state-of- the-art development tools for DSP and application programming (In circuit emulators, 64bit support, version control systems), programmable logic design (VHDL synthesis and simulation, in circuit programming, logic analysers, chip scope) and electronic development. In the SEM lab, the lithography systems can be tested in a real environment on electron beam systems, including resist chemistry.
