It’s unpleasant enough when you have to receive medical treatment. But it’s unbearable to sit in a room full of waiting patients, hoping for their turn. The waiting time can be shortened considerably with the mobile laboratory system from Fraunhofer IZM, as it allows faster diagnosis of diseases.

We would like to invite you to join us for a small time travel through the highlights of 20 years of Microelectronics News, and we hope you enjoy reading our selection of research and development from the member institutes of the Fraunhofer Group for Microelectronics.
Sustainability in the electronics industry is a central topic for economy, science and politics. Whether it’s about energy efficiency or the minimization of ecological follow-up costs – Companies are increasingly looking for approaches enabling them to cut costs and reduce environmental impact at the same time.

Small sphere – big bang. Researchers at Fraunhofer IAF manufacture tiny, high-precision hollow spheres out of synthetic diamonds. The starting point are small silicon spheres, which get coated with diamonds in a patented plasma reactor developed by Fraunhofer IAF. In contrast to the disk, the balls have to be moved permanently in the reactor for a homogeneous coating. Nevertheless the silicon is still in the sphere. To get it out and to create a hollow sphere, the researchers drill with a laser a only few micrometers tiny hole and dissolve the silicon with a special ultrasound-assisted etching technology. Christoph Wild, Eckhard Wörner and Dietmar Brink from Fraunhofer IAF were awarded with one of the Joseph von Fraunhofer Prizes 2006 for their development work.

With their new technology, researchers at the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute have developed a data rate of 2.56 Tbit/s in a wavelength channel over a distance of 160 km. This data rate corresponds to the content of 60 DVDs, which can be sent every second, and it´s twice of what a Japanese working group had accomplished five years earlier.
