Glass meets Flexibility


Dr. M. Junghaehnel from the Fraunhofer Institute for Electron Beam and Plasma Technology FEP (Fraunhofer FEP) will give an overview of advances in the area of flexible glass coatings and collaborative findings with Corning Incorporated (NYSE: GLW) at the SVC TECHCON 2014 being held at the Hyatt Regency in Chicago, May 3-8, 2014.

Flexible glass, such as ultra-slim Corning® Willow® Glass, produced at thicknesses of 100 micron and 200 micron has the ability to bend, while maintaining perfect barrier properties, superior surface quality, greater transparency, and high temperature processing, outperforming polymers. At the same time it has the potential to be used in roll-to-roll large area processing. These qualities make flexible glass an outstanding material for displays, touch panels, thin-film batteries and Photovoltaic (PV) products. According to Frost & Sullivan’s report »Innovations in Encapsulation Technologies for Printed Electronics (Technical Insights), D513-TI«, flexible glass poses tough competitions to polymer-based solutions.

Fraunhofer FEP aims to advance processing and handling of flexible glass. Fraunhofer FEP and Corning are working together to promote functionality of a glass surface using PVD deposition methods to facilitate device processing; remaining aware of the thermal and size parameters of the coated substrate, and the effects they could have on device fabrication.

During her presentation, Dr. Junghaehnel will focus on optimization of the magnetron sputtering process for low-stress deposition and emphasize the impact of selected process parameters during high-deposition sputtering of selected materials on the stress of a substrate. These results have been compared with investigations on flexible PET substrates. The determined parameters will be a starting point to improve handling and performance of flexible glass in existing thin-film coating equipment. Fraunhofer FEP’s thin-film coating equipment is suitable for substrates up to 200 mm in width and will be developed for roll-to-roll, high-rate deposition coating of flexible glass.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
