2 Austrians win Laser Student Paper Award with their paper on Applications in Microelectronic and Optoelectronic Manufacturing

Bernadette Egle won the Best Students Poster Award with her presentation of her research project at the world's largest exhibition for laser, photonics and biomedical optics in San Francisco. Two recent Nobel laureates were at also presenting at this exhibition. The two Vorarlberg research students won against students of 10 renowned universities in Asia, Europe and the US, which also submitted so-called ‘Students Posters’. On these posters, research projects are presented scientifically in a short, standardized form. They were able to show how ultrashort pulse lasers can improve the cutting quality on high-performance electronic chips. The results of their research are now being incorporated into the research and development work at Infineon.

 

You can find the Infineon electronics chips in many applications of everyday use:  in the car, in industrial electronics or in smart cards. These chips are manufactured by the thousands on 60 micron thin Si-wafers and then have to be cut. Usually a diamond saw is used to do this. Using this method, however, can cause microscopic chippings. For Infineon, this raises the question of whether the cutting quality (and thus also the reliability of the chip) can be improved by using the most precise available lasers. Such lasers are produced in Vorarlberg by Spectra Physics Rankweil. As the Vorarlberg University of Applied Sciences (FH Vorarlberg ) and their "Josef Ressel Center for Material Processing with Ultra Short Pulsed Laser Sources" owns such lasers and also has the corresponding research expertise, Infineon asked the Vorarlberg University of Applied Sciences for a study.

 

Bernadette Egle researched the question of Infineon as part of her bachelor thesis. The 22-year-old student was able to demonstrate how to set the laser to achieve the highest quality of cut. She was supervised in her bachelor thesis by Matthias Domke, a young researcher in the Josef Ressel Center of the FH Vorarlberg.

 

Thanks to long-term funding commitments colleges and their respective partner companies are able to perform multi-year research. This is also the case for the Josef Ressel Centres, which are funded by the federal government and research institutions sponsored by corporate partners. The cooperation of the University of Applied Sciences Vorarlberg with Spectra Physics has been in place for many years and was expanded in 2013 with the commissioning of a new Laser Design Plant. The plant was equipped by Spectra Physics with  ultrashort pulse lasers of the latest generation called SPIRIT, allowing the new Ressel Center to perform production-related research projects with high level of integration.
