Embedding & Substrate Technologies

The group Embedding & Substrate Technologies deals with the development of new processes for organic substrates and the embedding of components into substrates. The specific topics of work are:

  • Embedding Technology for active and passive components
  • Stretchable Electronics
  • PCB Finish and Reliability
  • Micro Galvanic
  • Substrate and components Biocompatibility

The group has a full process line for manufacturing of organic substrates up to 18"x24" format. It contains equipment for lamination, laser drilling, mechanical drilling, Laser Direct Imaging (LDI), galvanic, etching and electrical testing. Innovative technologies are developed and transferred into production scale. Beside cooperation with partners from industry and research, prototypes and small series are manufactured. Several process transfers to customers have been made already. All technologies developed within the group are available for licensing.

The evolution of very fast-switching semiconductors on silicon carbide (SiC) and gallium nitride (GaN) basis opens the gates for completely new standard power converters. The key is to not simply replace silicon semiconductors in a standard case – the minimal improvement in performance would be too dearly bought.

The use of SiC semiconductors in drive inverters is becoming increasingly popular. SiC offers the possibility of increasing the power density and efficiency in the system through lower switching and conduction losses compared to silicon FETs.
