Electronics and Micro System Technology

Further miniaturization and greater integration are driving the relevant trends in electronics. Thanks to the successful development of EUV lithography, Moore's Law continues to be valid – with even smaller structures. To implement and evaluate this technology, the experts of Fraunhofer ILT are developing the necessary beam sources and the corresponding measuring technology.

Not only is generating structures on a nanometer scale important, but the assembly and connection technology for high-performance electronic components also plays a decisive role in this sector. Fraunhofer ILT is able to meet the increasing demands – for higher integration density and higher operating temperatures, combined with greater robustness – by employing new interconnection technologies used in the backend as well as in the power sector of electronic components. This applies in particular to e-mobility, in which high current carrying capacity is coupled with small installation space. Together with industrial partners, Fraunhofer ILT is developing new bonding techniques for battery contacts and IGBT power components, which will be integrated into high-performance manufacturing systems.

Other competencies of Fraunhofer ILT include the structuring and functionalization of surfaces as well as 3D volume structuring. For example, selective laser etching allows microscopic structures to be incorporated into glass or sapphire substrates to generate microfluidic systems for biochemical analysis.

The collection of component condition data such as thermal and mechanical stress forms the basis for predictive maintenance, Big Data and AI approaches. For this purpose, components must be equipped with suitable sensors. Additive manufacturing methods such as laser powder bed fusion (LPBF) offer a wide range of possibilities for producing application-adapted components. Laser-based coating approaches can be used to additively manufacture sensors directly on component surfaces, e.g. through the wet-chemical deposition of electrically insulating and conductive materials; subsequently laser radiation is used for thermal post-treatment of the printed layers.

Fraunhofer ILT combines different manufacturing methods to equip printed lightweight components with printed sensors. By combining LPBF with digital printing and laser post-treatment processes in an innovative process chain, Fraunhofer ILT is paving the way for the production of »sensing« components. When installed, the manufactured component enables users to permanently monitor the component, document component load and detect overload conditions.

Such components can be used in classic areas such as drive or gear technology, large machines, power generation, rail vehicles and aerospace. By producing component and sensor in one step, research will be able to open up new fields of application – such as automotive, consumer electronics and toolmaking.
