MatInWLP

Material innovations for wafer-level packaging technologies

Subject of research

Wafer-level packaging (WLP) is an emerging, resource-saving technology in microsystems technology that also enables higher integration densities in the resulting electronic components. In addition, WLP is significantly more sustainable, as it requires less material and energy. The planned research project pursues an interdisciplinary approach of microsystems technology and materials science to harness new material concepts and processes for WLP in microelectronic production.

Results

  • Development of high-performance wafer bonding systems and solderable metallizations based on resource-saving thin-film systems
  • Evaluation of innovative 3D electronics printing technologies for structured deposition at wafer level
  • Development of a concept for the efficient introduction of new and environmentally compatible materials and recyclable process chemistry in production and large research cleanrooms
