The Fraunhofer Institute for Microstructure of Materials and Systems (IMWS) is a non-university research facility of the Fraunhofer Society for the promotion of applied research in Halle (Saale) .

It emerged from the Institute for Solid State Physics and Electron Microscopy of the Academy of Sciences of the GDR. From 1992 to 2015, the Fraunhofer IMWS was part of the Halle branch of the Fraunhofer Institute for Mechanics of Materials IWM, which was founded in 1971 in Freiburg im Breisgau . The Fraunhofer IMWS is a methodically oriented Fraunhofer Institute in the specialist disciplines of materials science and engineering . The work of the Fraunhofer IMWS aims to identify defects and weak points in materials, components and systems on the micro and nano scale, to clarify their causes and to offer customers solutions based on this. The institute's industrial clients come from the fields of microelectronics and microsystem technology, photovoltaics, plastics technology, the chemical industry, energy technology, automobile construction and aircraft construction.

Business areas and services

The IMWS works in the field of components of microelectronics and microsystem technology : This is about physical error analysis for semiconductor technology (e.g. single transistor, interconnect system), error diagnostics and material evaluation for connection technology and system integration (e.g. wire bond or solder contacts) the analysis of material interactions with process parameters and application conditions and process step optimization, the development of methods for the detection, target preparation and analysis of defects as well as the determination of local residual stress in the nanometer range, the strength and service life assessment of sensors and actuators of volume and surface micromechanics as well as wafer-bonded systems and finally the development of test methods for silicon microsystems (e.g. pressure, acceleration, rotation rate sensors or micro nozzles) at wafer or chip level.

In the area of ​​polymer application, the focus is on material design and the determination of complex material models including prototypical production of masterbatches , the design of components made from polymers and polymer-based material systems, and the production of prototypical components using injection molding , profile extrusion, injection molding compounding, film extrusion and reactive polyurethane -Technology for the mechanical and microstructural evaluation of materials and components and the development of microstructure-based simulation methods and test concepts for highly stressed fiber composite lightweight structures.

In the field of biological and macromolecular materials, the focus is on the development and evaluation of joining processes for polymer films, mechanical tests of films and fabrics, surface modification of polymer films with plasma technologies including inline process monitoring, and the interface engineering of biological and biocompatible materials for tissue engineering the surface functionalization and structural analysis of dental materials, the development and use of nanoporous membrane materials, the investigation of the morphology and microstructure of biological materials and plastics using electron microscopic methods and the further development of preparation and examination techniques (cryo-technologies, focused ion beam technology) the mechanical testing and evaluation of biological and biocompatible materials under physiological conditions and the development of components for biosensors.
