  3. Fraunhofer IMS Foundation: 1984/85 Staff: > 200 Mission: • Applied Research, development, and production of innovative microelectronic products • Technology development and transfer Budget: (18,8 Mio. Euro for 2008) 25 % basic funding for corporate research and administration 25 % publicly funded projects 50 % projects funded by industry product devel. industry applied research Fraunhofer- Gesellschaft Max-Planck-Gesellschaft basic research 100% public 100% privat

  4. IMS Infrastructure • Clean Room of IMS Duisburg • Total area: 1300 m2 • Clean room class: 10 • Wafer size: 200 mm (8 inch, 0.25µm) • Staff: app. 90 in 4 shifts / 7days a week • Capacity: > 70.000 wafer/p.a. • Production range • Complete CMOS process line plus integrated sensors • Production from some 100 ASICs/p.a. - > 1,000,000 ASICs/p.a.

  5. IMS Infrastructure • Microsystems Lab • Total area: 400 m² (600 m² in 2008) • Clean room class: 10 • Wafer size: 200 mm • Staff: 5 + • Mission: Extending the application areas of CMOS (“More than Moore”) by Post Processing on CMOS wafers • Development Activities • Adding layers, structures, devices onto preprocessed “intelligent substrates” (CMOS wafers) to create integrated sensor systems. Examples: Bolometer arrays for IR imaging, Biosensors

  6. Currently used Applications of Transponder Systems • Immobilizer of Passenger Cars • Electronic Ear-Tag • Control of Material Flow in Production • Sports Timing (e.g. Marathon) • Access control at Skiing Lifts • Baggage Sorting • Maut Control • Building Automation • Waste Management • . . .
