Experts in micro- and nanotechnology

Micronova is the leading research centre for micro- and nanotechnology in Finland, with over 300 researchers from VTT Technical Research Centre of Finland, Helsinki University of Technology, and the corporate sector. Located in the heart of the Otaniemi Science Park, the largest technology hub in the Nordic countries, Micronova acts as an enabling resource for integrating leading-edge scientific knowledge with industrial applications.
Work at Micronova embraces all aspects of the micro-nano innovation chain, from basic R&D to prototype development and small-scale manufacturing.

Micronova's greatest strengths are its interdisciplinary personnel, excellent processing capabilities for nano- and microdevices, and extensive technology base for integrating basic research on physics, chemistry, biology, and new materials into photonic devices, microsystems, and microelectronics.

Most of Micronova's R&D is carried out in close cooperation with partners at universities, research institutes, and companies, in Finland and elsewhere. Close collaboration with industry, together with the centre's manufacturing services, have attracted several companies to base their R&D efforts at Micronova.

Education is also a major activity, with lectures and laboratory courses in micro- and nanotechnology. An international master's programme is offered in English. Over 60 graduate students are involved in work on advanced research projects.

Wide-ranging expertise

Microsensing and photonics are particularly strong fields of research at Micronova. Other focal areas include nanofabrication, micro­systems (MEMS), wireless communications systems, biosensors and fluidics, quantum devices, and millimetre-wave and optical instruments.

Micronova devotes significant resources to developing sensors, sensor arrays, and associated electronics and packaging. A number of sensors for pressure, temperature, and acoustic emissions have been developed, as well as X-ray and particle detectors.

Micronova's technology base covers most of the electromagnetic spectrum, opening up new avenues for remote sensing. The centre is also active in chemical and biological sensing, including DNA chips.

Novel optoelectronic devices, nano-optics, silicon microphotonics, and fibre optics, represent core areas of photonics expertise at Micronova.

This has seen the development of visible and UV LEDs and lasers, supercontinuum sources, fibre amplifiers for optical communications, and instruments for laser spectroscopy and interferometry.

Flexible organic light-emitting diodes (OLEDs) and organic transistors and diodes have also been demonstrated; and new low-cost manufacturing technology developed for polymer electronics, such as imprint, UV, and gravure and flex printing.
