Located in the basement at the LIT Open Innovation Center and funded by the Austrian Federal Ministry for Science, Education & Research, the JKU and the state of Upper Austria, the new cleanroom has been designed to manufacture scientific samples for base-knowledge research as well as produce prototypes to be shared with different institutes and departments (physics, chemistry, mechatronics, computer science).

Areas of application include quantum technologies, particularly new semiconductor-based light sources to secure data transfer via quantum key distribution, silicon-based photonics with potential applications in data transfer (data-centers), sensor technology, wearable electronics (e.g. for medical applications), ultra light photovoltaics, etc.

The cleanroom environment drastically reduces the number of airborne particles and is vital in an effort to create devices in the micrometer and nanometer range.

What is a Cleanroom?

In comparison to the air composition in a regular lab, the concentration of airborne particles in a cleanroom are greatly reduced. Reduced particles are vital in the production of electronic and optoelectronic devices as undesirable dust particles could impair the way the affected structures (often just one micrometer in size) work. Inside of a cleanroom, the air quality, temperature and humidity can be steadily controlled by using ventilation systems and filters. This is also important in order to reproduce the production processes. Those working in a cleanroom are required to wear special protective suits and shoes in order to keep the particle density as low as possible and use only corresponding equipment and materials. For example, regular paper cannot used in a cleanroom as it has a fiber structure.

Why do we need a Cleanroom at the JKU?

Various research groups at the JKU use cleanrooms and the air-controlled cleanroom environment, particularly the Institute of Semiconductor and Solid-State Physics as well as the Institute of Mechatronics. The new cleanroom at the OIC will not only support the production of new electronic and photonic devices for base-knowledge research as part of Austrian Science Fund, EU, ERC, and other projects that have potential applications in the fields of quantum technologies, photonics, flexible electronics, and sensor technology, but will also expand the application spectrum for users at different institutes (physics, chemistry, mechatronics, informatics). The goal is to share the use of these rooms and open the doors to interdisciplinary research projects and educational strategies in the area of “digital transformation”.
