The air-conditioning system and most of the cleanroom structures that were damaged in the fire have been completely replaced. Covering a floor area of 1,100 m², the cleanroom suffered considerable damage in the fire, with the cost of renovation and refurnishing estimated at approximately EUR 13.5 million. The new and restored research equipment is currently being installed, and process start-up was begun at the same time as the installation work. The facilities are expected to be in full working order and available for research by the end of the year.
The cleanroom serves research in micro- and nanoelectronics, using equipment such as a CMOS-based production line for integrated circuits and MEMS components, as well as specialised equipment for deep etching in silicon and silicon dioxide. The facilities also house equipment required for materials research, particularly for the needs of nanoelectronics research.
Much of the research equipment destroyed in the fire has been replaced with new, equally powerful equipment. For example, migration from 100 mm to 150 mm wafer size in the production of integrated circuits and semiconductor components can be regarded as a significant improvement, furthering VTT's partnering opportunities with the industrial sector.
Micronova is a leading centre for excellence in micro- and nanotechnology run jointly by the VTT Technical Research Centre of Finland and the Helsinki University of Technology. There are nearly 300 research specialists working at the Micronova facilities in Otaniemi, Espoo. This building is the largest cleanroom used for micro- and nanoelectronics in the Nordic region. Micronova partners with various universities, research institutes and commercial enterprises in international world-class research.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
