The sustainability check for your processes in microelectronics production

Services from Hub III: Resource-optimized electronics production

We examine your microelectronics production and develop proposals to reduce your CO2e footprint. Apply for a validation project and have your innovative manufacturing process checked right through to the product free of charge!

Areas examined: 

  • Resource-optimized microelectronic processes 
  • Energy-efficient cleanroom environment 
  • Decrease of harmful exhaust emissions 
  • Optimization of individual processes in terms of energy and material consumption 
  • Sustainable design and connection technology 
  • Replacement of critical materials (CMR and/or PFAS materials) 

Focus topics: 

  • Consideration in operation: energy savings in selected scenarios 
  • Consideration of the resource input during production by determining the CO2e footprint (if information is available for the calculation or assessment).
  • We offer to carry out a life cycle assessment for your manufacturing processes.
  • The validation project's result is presented as a case study (theoretical consideration), which illustrates the savings potential through Green ICT technology. The final results are also published. Company-specific data will be treated confidentially on request.
