RADAR is a 7-member consortium that aims to develop a robust, sensitive, and versatile label-free, biosensor platform for spot measurements and on-line monitoring of toxins and pollutants in food production processes and in the aquatic environment. Specificity towards chemical pollutants and toxins is achieved by using recombinant receptors (namely the estrogen receptor and the aryl hydrocarbon receptor) whose amino acid sequences have been rationally designed based on genomic and functional information from aquatic organisms. Sensitivity of the biosensor is increased by the unique combination of isotachophoretic pre-concentration step, and surface nanostructuring & chemical modification. The integration of the label-free detection sensors with an on-line automated sample handling and a wireless communication system will yield a best-in-class biosensor platform for robust, specific and sensitive detection of EDCs and PAHs in difficult operating conditions. To validate the RADAR biosensor the consortium will test the biosensors in fresh and marine water, in fish farms, and in food products such as fish, fruit juices, and milk. Through their contacts in these industries, the partners will evaluate the performance of the biosensors in such environments, analyzing a representative number of samples and reporting on the stability, ruggedness and accuracy of the sensors used under laboratory and real test conditions. This project is expected to have a high economic impact, since our cost-effective sensor could find a worldwide distribution in most food production and water testing lines as supported by Agilent Technologies Inc.

Liquid precursor material of a coating substance and a solvent is provided in a reservoir (STEP1, STEP1). In one variant the liquid precursor material is distilled (STEP2), the resultant liquid coating substance is vaporized (STEP3) and ejected through a vapour distribution nozzle arrangement (7) into a vacuum recipient (3) and onto substrate 5 to be coated. Alternatively, the liquid precursor material is directly vaporized (STEP3). From the two-component vapour coating substance vapour is applied to substrate 5 to be coated. In this variant separation of solvent vapour and coating substance vapour is performed especially downstream vaporizing (STEP2).

The NanoHiTEC project is focused on planar thermo-electric converters based on super-lattice quantum wells, which have shown on laboratory scale already a figure of merit ZT > 4 for a wide temperature range. The optimization of BiTe based layer systems as well as Si/SiGe and B4C/B9C lattices will be combined with the development of low cost/high throughput industrial deposition processes for multilayers. Direct p-n-junctions at the hot side of the converter promise further increase in performance and long term stability of the devices, but also simplified fabrication. As technologies for improved material performance multilayered nanowires and sintered nanopowders will be investigated. A central point of NanoHiTEC is the optimization of the passive components (thermal and electrical contacts, substrates) and of new geometries for the layout of planar converters to maximize the system efficiency. In this field particular emphasis is given to the heat flow into the hot and out of the cold side of the active elements where actual devices show the most efficiency loss. The developments in the project are backed by partners experienced in the qualification of thermo-electric materials and devices. Besides the parameters defining the thermoelectric performance - measured in a wide range of temperatures, pressures and magnetic fields - the microstructure, dopant distribution and the inner potentials will be investigated by scanning microscopy and TEM (holography). A major part of the project is the simulation of electronic and phononic properties based on the material microstructure. Intense interaction of theoretical work and characterization results of fabricated systems will pave the way for further enhanced material efficiency and better producibility. A main target is the integration in automotive applications where the high efficiency of superlattice systems over a broad temperature range promises good adaptation to the varying conditions in vehicles.

A sputtering apparatus is provided n which a method of magnetically enhanced sputtering an electrically-conductive material onto interior surfaces of a trench can be performed, which includes providing a magnetic field adjacent to a target formed at least in part from the electrically-conductive material, and applying a DC voltage between an anode and the target as a plurality of pulses. A high-frequency signal is applied to the pedestal supporting the semiconductor substrate to generate a self-bias field adjacent to the semiconductor substrate. The high-frequency signal is applied to the pedestal in pulses, during periods of time that overlap with the periods during which the DC voltage pulses are applied. The periods of time that the high-frequency signals are applied include a duration that extends beyond termination of the DC voltage pulse applied between the anode and the target. During each DC voltage pulse the electrically-conductive material is sputter deposited onto the side walls of the trench formed in the semiconductor substrate.


A transport and handing-over arrangement for disc shaped substrates, comprising a carrier (3) and a take-over arrangement (15). Both are moveable relative to each other. A relatively heavy substrate carrier (7) of magnetisable material is taken-over from the take-over arrangement (15) by distance control of a permanent magnet (17) at the take-over arrangement (15) or is returned therefrom to a carrier (3). The controlled drive of the permanent magnets (17) in the take-over arrangement (15) is performed by means of pneumatic piston/cylinder arrangements (19).


A method of magnetron sputtering, comprises rotating a magnet of a magnetron with an angular frequency , and, during sputtering of material from a source of the magnetron onto a substrate, periodically modulating a power level applied to the source with at least a component comprising a frequency f which is a harmonic of the angular frequency of rotation of the magnet other than the first harmonic.


A silicon wafer-based solar cell with a two-layer antireflective coating (ARC) combines a 10-30nm thick hydrogen containing passivation layer (e.g. Si_(X)N_(Y):H) with a top layer of Nb_(2)O_(5) (or Nb_(X)O_(Y) in general) for optimal matching the refractive index of the ARC to cover materials having a refractive index of about 1.5 (e.g. glass or EVA, Ethylene Vinyl Acetate). The two-layer ARC can be deposited either by PECVD or by reactive sputtering (PVD) of a Si target with N_(2) and/or NH_(3), and the Nb_(2)O_(5) layer is deposited by reactive sputtering of either a pure Nb target or a conductive Nb_(2)Ox (x<5) target with O_(2).


An apparatus for generating sputtering of a target to produce a coating on a substrate is provided. The apparatus comprises a magnetron including a cathode and an anode. A power supply is operably connected to the magnetron and at least one capacitor is operably connected to the power supply. A first switch is also provided. The first switch operably connects the power supply to the magnetron to charge the magnetron and the first switch is configured to charge the magnetron according to a first pulse. An electrical bias device is operably connected to the substrate and configured to apply a substrate bias.
