Organic substrates and panel level packaging

Target

  • Development and fabrication of multi-layer electronic interconnection architectures based on resin layers which typically include specific filler particles or glass cloths (organic substrates)
  • Cover a wide range of applications from ultra dense chip interposers to high power applications using adapted materials and process approaches
  • Large area panel level fabrication using advanced printed circuit board process technologies 
  • Organic substrate processes as basis for heterogeneous integration of single or multiple electronic components into the substrates
  • Improvement of electronic functionality and reliability and size reduction of systems or packages at the same time

Innovations

  • Fine line processing down to 2 µm line/space copper interconnects in multilayer circuit architectures with ABF/BU dielectric 
  • Vertical interconnect with diameter down to 10 µm
  • Use of glass panels in the core of organic multilayers
  • Implementation of specific materials for applications in high frequency, power, and medical electronics respectively

Impact 

  • Next generation high routing density interposer fabrication
  • 6G and beyond miniaturized system
  • Power electronic modules with highest efficiency and reduced weight and volume
  • Highly versatile set of process technologies for a multitude of applications
