The SUBLIMA project aims at truly simultaneous, fully integrated, solid-state PET/MR technology for concurrent functional and anatomical imaging with unsurpassed image quality. It will combine the extremely sensitive functional imaging possibilities provided by PET with the excellent soft-tissue contrast and complementary functional imaging capabilities of MR. For the first time, time-of-flight (ToF) and depth-of-interaction (DoI) correction will be introduced together into a PET/MR system. SUBLIMA will also be the first to exploit the unique advantages of truly simultaneous PET/MR acquisition by enabling fully 4D MR-derived motion correction. Furthermore, artefacts seen in PET-CT will be eliminated by developing MR-based, motion-compensated PET attenuation correction. The SUBLIMA platform will thus realize a breakthrough in image quality and enable novel applications in oncology, cardio-vascular medicine, and neuro-degenerative diseases. SUBLIMA will not only introduce new methods and technologies in each important component of the imaging chain, but it will also analyse the system performance as a function of all relevant design parameters, in order to push the image quality to the physical limits by optimally merging these innovations into 7T preclinical and 3T whole-body human demonstrator systems. This integrated approach also warrants adaptation of the project results for optimum performance in stand-alone PET and SPECT applications. The consortium, lead by Philips, consists of universities, research institutes, industrial partners, and SMEs, spread over 7 different countries including the USA. While each partner has shown exceptional quality in its own field, the consortium brings together the wide and complementary range of expertise necessary to push the performance of ToF-PET/MR to the physical limits.

Various emerging markets in the field of non silicon multimaterial micro devices offer a huge potential for commercialisation in the near future. However, solutions for mass-production for most of them have still to be developed. The objective of the MULTILAYER project is to develop a set of solutions for the large-scale production of micro devices based on a technology we call Rolled multi material layered 3D shaping technology and using the concept of tape casting and advanced printing techniques. This technology will enable to manufacture complex multifunctional 3D-micro parts on a layer by layer manner and in a high-throughput context. Each layer can be given a specific structure. They will be printed and contain channels and cavities that are open or filled in a very high precision manner. The microsystems will have as basic building material ceramics, which is a clear advantage in applications that require high temperature, corrosive environments and long time reliability. Furthermore, it will allow spatial resolutions under 10 m and the ceramics tapes developed will be down to 10 m thin. The Rolled multi material layered 3D shaping technology will have several advantages: - it will be an efficient mass production method - the fabrication series can attain over a million units - it will offer a good flexibility for a wide variety possible component designs, - it will allow the integration of different materials as different layers enabling to manufacture multimaterial multilayered packages with a high degree of integration, - the process will be very reliable, indeed, every single layer can be advantageously inspected and controled

The purpose of this work is to evaluate the feasibility of room temperature wedge-wedge bonding using commercially available copper wires, coated with aluminum. Bonding quality, reliability and aging resistance of the wire bonds have been investigated using standard wire pull tests immediately after bonding and after accelerated life tests, including temperature storage at 125 °C, 150 °C, and 200 °C for up to 2000 h. Using focused ion beam (FIB-) preparation and high resolution electron microscopy (SEM, TEM combined with EDX X-ray analysis), results of microstructure investigations of the Al-coating/Cu wire interface as well as of the bonding interconnect formed between the coated wire and the metallization on ceramic substrate will be presented. These investigations provide background information regarding the binding mechanisms and material interactions, and contribute to assess and to avoid potential reliability risks. Due to the found advantageous bond processing behavior and increased reliability properties, our results indicate that room temperature wedge-wedge bonding of coated copper wires has a remarkable application potential, for instance in medical and other high reliability as well as high power applications. It combines all known advantages of usual copper bonding like excellent contacting behavior, high reliability and favorable material price with the possibility of processing temperature damageable components and considerable improved storage capability. Therefore, room temperature bonding using coated copper wire can also reduce cycle time, manufacturing and material costs. © 2010 Elsevier Ltd. All rights reserved.

The originality of this work consists in printing on ceramic tapes conductive silver tracks that reach a low resistivity by flexography process. Flexography is a solution for the mass production of multimaterial microdevices offering a huge potential of commercialisation in the near future. In order to test the flexography printing process for microelectronic application on Low Temperature Cofired Ceramic (LTCC) tapes, a screen printing paste was optimised to reach flexography printing requirements. Ink with 30% silver per weight was prepared and printed by flexography, roll to roll (R2R) process, on LTCC substrates. Three to five print passes were performed. Printed lines were sintered during 10 min at a peak temperature of 850°C under normal air atmosphere. Conductive lines, with a mean width of 190 μm, a mean thickness of 1.50 μm and a resistivity of 2.8 × 10 -8 Ω m close to bulk silver resistivity, were achieved after sintering. © 2012 Elsevier Ltd.

The ongoing trend to miniaturized electronics has induced many developments towards size reduction and increasing performance in electronic products. To meet these requirements the involved processes, materials and components in electronics production have to be enhanced for high performance and high reliability. Flip-chip technology is one technology of choice with potential for highest integration. In previous investigations technologies for cost-efficient solder bumping and automated assembly in an industrial environment were evaluated. Wafer level solder sphere transfer and solder sphere jetting were adapted to provide flipchips with solder bump diameters down to 30 μm for flip-chip assembly onto printed circuit boards as well as onto thin film ceramic substrates. The reliability tests done so far showed excellent achievable reliability performance of these ultrafine-pitch assemblies under various test conditions. Since electromigration of flip-chip interconnects is a very important reliability concern, characterization of new interconnect developments needs to be done regarding the electromigration performance in accelerated life tests. For all experiments, specially designed flip-chips with 10 mm by 10 mm by 0.8 mm in size have been used. The silicon die layout provides a pitch of 100 μm with solder bump sizes between 60 μm and 30 μm in diameter. The solder spheres consist of lead-free SnAgCu alloy and are placed on a Ni-P under bump metallization which has been realized in an electroless nickel process. For the electromigration tests within this study, multiple combinations of individual current densities and temperatures were adapted to the respective solder sphere diameters. Online measurements with separate daisy chain connections for each test coupon provide exact lifetime data during the electromigration tests, which are in some cases still in progress. Cross sectioning has been employed for the analysis of thermal diffusion as well as of the impact of electromigration influence on the failure mechanism using optical, SEM and EDX analysis, respectively. Reliability plots will be discussed regarding the electromigration performance for different test conditions applied to the respective test specimen for lifetime estimations. © 2012 IEEE.
