    Abstract: An optical detection system (100) for detecting biological, chemical or bio-chemical particles is described. The optical detection system (100) typically comprises a surface mode interference means. The surface mode interference means may comprise a layer (102) such as for example a metal layer like e.g. a gold layer. The surface mode interference means furthermore typically is adapted to create an interference effect between optical interface modes of the layer to detect optical changes in the vicinity of the layer (102). In this way, sample (106) occurring in the vicinity of the surface may be detected. The present invention furthermore relates to a method for performing optical detection and to a method for setting up an optical detection system wherein parameters are selected for tuning the surface mode interference means to a desired wavelength range and/or to a desired range of analyte refractive indices.

  • Patent number: 7521369
    Abstract: A method is disclosed for the selective removal of rare earth based high-k materials such as rare earth scandate high-k materials (e.g. DyScO3) over silicon or silicon dioxide. As an example Dy and Sc comprising high-k materials are used as a high-k material in gate stacks of a semiconductor device. The selective removal and etch of this high-k material is very difficult since Dy and Sc (and their oxides) are difficult to etch. The etching could however be easily stopped on them. For patterning of the metal gates comprising TiN and TaN on top of rare earth based high-k layer a chlorine-containing gases (Cl2 and BCl3) can be used since titanium ant tantalum chlorides are volatile and reasonable selectivity to other material present on the wafer (Si, SiO2) can be obtained. The Dy and Sc chlorides are not volatile, but they are water soluble.

  • Publication number: 20090091011
    Abstract: The present invention is related to a method of producing a semiconductor device and the resulting device. The method is suitable in the first place for producing high power devices, such as High Electron Mobility Transistors (HEMT), in particular HEMT-devices with multiples source-gate-drain groups or multiple base bipolar transistors. According to the method, the interconnect between the source contacts is not produced by air bridge structures, but by etching vias through the semiconductor layer directly to the ohmic contacts and applying a contact layer on the backside of the device.

  • Patent number: 7511116
    Abstract: A technique is described for the preparation of polymers according to a process in which the starting compound of formula (I) is polymerized in the presence of a base in an organic solvent. No end chain controlling agents are required during the polymerisation to obtain soluble precursor polymers. The precursor polymer such obtained comprises structural units of the formula (II). In a next step, the precursor polymer (II) is subjected to a conversion reaction towards a soluble or insoluble conjugated polymer by thermal treatment. The arylene or heteroarylene polymer comprises structural units of the formula III. In this process the dithiocarbamate group acts as a leaving group and permits the formation of a precursor polymer of structural formula (II), which has an average molecular weight from 5000 to 1000000 Dalton and is soluble in common organic solvents. The precursor polymer with structural units of formula (II) is thermally converted to the conjugated polymer with structural formula (III).

  • Publication number: 20090079494
    Abstract: A method of operating a quantum system comprising computational elements, including an insulated ring of superconductive material, and semi-closed rings used as an interface between the computational elements and the external world, is disclosed. In one aspect, the method comprises providing an electrical signal, e.g. a current, in an input ring magnetically coupled to a computational element, which generates a magnetic field in the computational element and sensing the change in the current and/or voltage of an output element magnetically coupled to the computational element. The electrical input signal can be an AC signal or a DC signal. The computational element is electromagnetically coupled with other adjacent computational elements and/or with the interface elements. The corresponding magnetic flux between the computational elements and/or the interface elements acts as an information carrier. Ferromagnetic cores are used to improve the magnetic coupling between adjacent elements.
