Fraunhofer FEP is an experienced partner for technological developments, known for testing the limits of new materials and for optimization of those materials with respect to market demands. Currently, researchers are dedicating their efforts to investigations of ultra-thin glass. The focus of recent activities is sheet-to-sheet coatings on large-area ultra-thin glass.

Those activities can be divided into several phases. In the first phase, the researchers work out and adapt standard vacuum processes with regard to a demanding material – ultra-thin glass. The handling requirements and the machine set-up are developed in the next phase: After all, the glass should be treated through the in-line vacuum process without any damage or breakage. The machine design is also adjusted in order to safely coat large-area ultra-thin glass. The pre-treatment of glass also plays an important role in this process. An optimized pre-treatment enables a reliable processing of ultra-thin glass with superior coating properties.

With its experience and knowledge in the field of ultra-thin glass, Fraunhofer FEP is a leading research partner for sheet-to-sheet and roll-to-roll processes right through to application of this material in organic electronics.

“We have been collaborating with Corning Incorporated since 2012”, explains Manuela Junghähnel, coordinator of ultra-thin glass development at Fraunhofer FEP. “The results of these activities will be presented in a joint talk at the conference and through exhibits at the SVC TECHCON booth.”

Ultra-thin glass can be used as a substrate as well as for encapsulation in many smart products such as Smartphones, curved displays, OLED light sources and photovoltaics. Especially appealing is to use ultra-thin glass in wearable electronics as well as in intelligent micro-optics and touch-sensors.

Ultra-thin glass offers outstanding possibilities for deposition of transparent, electrically conductive films that are indispensable for numerous applications in high-tech electronics. Moreover, ultra-thin glass has excellent surface properties that considerably exceed the ones of conventional plastic films.

Fraunhofer FEP will be exhibiting its current work on large-area ultra-thin glass during SVC TechCon 2016. Manuela Junghähnel will also be presenting her recent research findings on ultra-thin glass in a tutorial course during the event.
