1 DTU DANCHIP an open access micro/nanofabrication facility bridging academic research and small scale production DTU Danchip National Center for Micro- and Nanofabrication

2 DTU Danchip DTU Danchip is Denmark s National Center for Micro- and Nanofabrication. 1350m 2 cleanroom class , 40 employees Copenhagen, owned by the Technical University of Denmark Mission: To provide Denmark with state of the art infrastructure, research facilities, technology and hands-on training within applied micro and nano fabrication technology. To constitute a direct link between applied university research and industrial applications. To facilitate the creation of new knowledge and enable Danish industry to exploit the existing and future benefits of nanotechnology.

3 Basic Concept - self service garage pay per use

4 Basic Concept Cost sharing: lowering the barrier of entry so all interested companies and research institutions have access to state of the art micro and nanotechnology without equipment investment. Critical mass of users assures: knowledge and expertise efficient operation and maintanence sharing of operation cost

5 DTU Danchip - academia as main customer - 20 % of activity in cleanroom comes from industry - from basic research to small scale production - all services: research, development, process engineering, fabrication

6 academic - industrial full control complete freedom

7 Micro/nano fabrication facilities every facility has its own balance Flexibility Research minded University Lab Quality control Reliability Small scale production Wafer fab Educating process engineers with up to 4 years cleanroom experience

8 What do we do? - research and facilitation of reserach - offer access to state of the art equipment - offer know-how and expertise - insource R&D projects - customer processing, consulting services - small-scale production - education and training in all aspects of practical micro and nanofabrication - offer cleanroom areas to rent What do we not do? - large scale production - support/initiate new technologies without critical mass of users

9 small scale production is essential for niche products fabless MEMS startups --- cannot survive without open access cleanrooms open access facilities enable technology entrepreneurship small businesses are the engine of global economy Transfer from development to fab too cost intensive for niche products hardware is hard easy money is in software

10 small scale production at Danchip no investment money for tools and equipment fabless MEMS, semiconductor startups prototype to first product has to be fast and cost efficient

11 Small scale production at Danchip making the most of it - run batches - costumer controlles and verifies wafers after number of process steps - specifications based on process monitor characterization/data As opposed to: - running continous production (on std. Danchip equipment) - specifications on functionality

12 DEEP UV Stepper services - Cassette to cassete BARC/resist spinning station - Cassette to cassete development station - 4, 6, 8 capability - full fabrication service or: - training of customers personnel Resolution 250nm, straight lines down to 160nm

13 CANON FPA-3000 EX4 DEEP UV 160nm Resolution 250nm, straight lines down to 160nm

14 E- beam services state of the art E-beam JEOL JBX9500 Min. spot size Min. line width Max. scan speed JBX9500 4nm 10nm 100MHz Max. writing field size 1000µm Min. step size Field stitch error Position accuracy within 6inch area 0.5nm 11nm 11nm

15 E- beam services - chip size, 2, 4, 6, 8 capability - full fabrication service or: - training of customers personnel - JEOL 9500 with cassette loadlock (up to 10 cassettes) min. line width ---- Writing conditions ---- Field size: 1000µm Current : 200pA Resist: ZEP520A Dose: 7580µC/cm^2 Shot pitch: 1nm Spec= 10nm or less Results = Max: 9nm, in X and Y

16 Different material platforms - joined equipment platform silicon magnetic III-V metals equipment II-VI? others? polymer carbon 16 DTU Danchip, Technical University of Denmark

17 Flexibility at a price - ensuring reproducability by duplicating of equipment - 5 ICP dry etchers - metal - silicon - polymer - III-V - oxide - wafer size 2, 4, 6 and 8 State of the art equipment (examples): - JOEL 9500 E-beam (delivered may 2012) - ION Beam Etch - DUV Stepper - Graphene CVD tool

18 What are we good at? access to advanced equipment for research and development within micro- and nanotechnology Low initial costs for new projects (cost sharing) Technological head start and rapid development of new areas through joint knowledgebase and sharing possibility to directly go from development to small scale production without cost and hassle to change facility experienced staff, 20 years track record

19 Examples of Applications (courtesy of DTU Nanotech) Commercial examples include: silicon microphones, optical waveguide circuitry, pressure sensors for wastewater, micro4pointprobes, etc

20 Summary DTU Danchip -Danchip offers services reaching from R&D to full small scale production - provides training to customer personnel - allows customers to carry out own R&D and production on Danchip tools
