Modular high-temperature reactor for the continuous synthesis of nanoparticles

Fraunhofer ICT-IMM presents a novel, modular reactor for continuous flow synthesis of nanoparticles at elevated temperatures. The reactor is capable of performing liquid-phase reactions at temperatures of up to 400 °C, common hot-injection synthesis protocols for the synthesis of nanomaterials can now be transferred from batch to continuous. Examples include organo-metallic syntheses as used for CdSe quantum dots (QDs), Pt and other metal nanoparticles, or oxide materials.

REACH and RoHS compliant thick-film paste portfolio

Power electronics is becoming a key technology for a rising number of products and systems due to a global trend to green energy and the establishment of electric mobility.
Our researchers now focus on high-performance and high-thickness screen-print pastes for AlN and Si3N4 as excellent buildup materials for power electronics and assemblies.
New additives, adopted organic vehicle, and modified manufacture technologies are used to tune properties such as the temperature coefficient of the resistor and adhesion strengths of solder joints. Our “Pastemeleon” awaits you on the booth!

Environmentally friendly water-based nanoparticle-printing inks and multilayerbased microsystems

Direct writing technologies like inkjet or aerosol printing for silver, copper, gold and platinum inks are promising methods to print contactlessly thin functional layers in order to realize optimized microelectronic devices such as circuit paths or heaters easily.
Fraunhofer IKTS develops those environmentally friendly water-based nanoparticleprinting inks for polymeric and ceramic substrates. The application of nanoinks for the wiring of surface mounting devices on low-temperature co-fired ceramics (LTCC) as well as extremely robust ceramic multilayer acceleration sensors are examples of new technologies presented on the booth.

The Fraunhofer IKTS conducts applications-oriented research in the field of high-performance ceramics. As research and technology service provider, the German institution develops ultramodern high-performance ceramic materials, industrially relevant manufacturing processes, prototype components and systems in complete production lines, through to pilot-scale production. At its heart are market-viable ceramic solutions for mechanical and plant engineering, energy and environmental technology, optics, medical technology as well as electronics and microsystems technology. The research portfolio is expanded with expertise in materials diagnostics and testing. The test procedures in the fields of acoustics, electromagnetics, optics, microscopy and laser technology contribute substantially to the quality assurance of customer’s products and systems. Nanomaterials often play the key role in innovations.

Magnetic field sensor

Fraunhofer ENAS will present a new type of spintronic magnetic field sensor with two-dimensional vector resolution for contact-free measurement of distances, speeds, and angles. The magnetic field sensor's functionality is based on the physical giant magnetoresistance (GMR) effect. Technologies such as PVD and plasma etching processes are employed for fabrication. Thanks to those micro- and nanotechnologies used, it is possible to attain a very high signal-to-noise ratio, very short response times, a high degree of miniaturization, and a very low level of energy consumption. The GMR sensor is also bio-compatible. Conceivable applications range from the aerospace and the automobile industry to the very latest devices in medical engineering.

Integration of Carbon Nanotubes and applications

Fraunhofer ENAS investigates the integration of nanomaterials like carbon nanotubes (CNT) and their application in electronics and sensors with industrial compatible technologies. Therefore we focus on wafer level technologies for CNT material fabrication as well as material conditioning, the assembling or site-selective growth of CNTs, contact formation and fabrication of CNT-based devices. Target applications are CNT based high frequency field effect transistors for communication applications as well as ultra-sensitive and miniaturized sensors.

Focus of R&D activities:

• Waferscale technologies for nanomaterial integration
• Integration of CNTs into interconnect systems and MEMS/NEMS
• CNT FETs for high frequency analogue applications
• CNT based sensors (e.g. piezoresistors in N/MEMS)
• Chemical vapour deposition of CNTs on wafer scale
• Wafer scale dielectrophoretic assembly of CNTs

Low-temperature Bonding

Fraunhofer ENAS offers these technologies for low-temperature wafer bonding:

• Room-temperature bonding by using reactive nano scale multilayer
• Anodic bonding (glass/Si)
• Direct bonding (glass/glass; glass/Si; SiSi)
• Adhesive bonding (SU-8; BCB)
• Solid-liquid interdiffusion bonding (CuSn)
• Thermo-compression bonding

The Fraunhofer Institute for Electronic Nano Systems ENAS focuses on smart systems integration by using micro and nano technologies and provides services in:

• Development, design and test of MEMS and NEMS (micro and nano electro mechanical systems)
• Wafer level packaging of MEMS and NEMS, wafer bonding, low temperature bonding
• Metallization and interconnection systems for micro and nano electronics as well as 3D integration
• Adaptive printing technologies inclusively material development and characterization
• Reliability and security of micro and nano systems.

In Sendai, the Fraunhofer Project Center “NEMS/MEMS Devices and Manufacturing Technologies at Tohoku University” was founded as a platform for common research and development activities of Tohoku University and Fraunhofer ENAS. The project center is run to the benefit of both partners as a vehicle for R&D cooperation, technology transfer as well as training and education programs.
