  • Publication number: 20100284860
    Abstract: An article is provided for immobilizing functional organic biomolecules (e.g. proteins, DNA, and the like) through a covalent bond to a thiolate or disulfide monolayer to a metal surface wherein an extra activation step of the surface layer or an activation step of the functional biomolecules or bioreceptors could be avoided. The monolayer can contain, but is not limited to, two moieties. One has a group that resists nonspecific adsorption and another has a group that directly (without activation) reacts with functional groups on the biomolecules. In addition, poly(ethylene oxide) groups are incorporated in the monolayer surfaces to resist the nonspecific adsorption and to enhance the specific affinity interactions. A sensor device including these monolayers is also provided to perform reproducible, sensitive, specific and stable bioanalysis.

  • Publication number: 20100285656
    Abstract: The present invention relates to a method for forming metal-silicide catalyst nanoparticles with controllable diameter. The method according to embodiments of the invention leads to the formation of ‘active’ metal-suicide catalyst nanoparticles, with which is meant that they are suitable to be used as a catalyst in carbon nanotube growth. The nano-particles are formed on the surface of a substrate or in case the substrate is a porous substrate within the surface of the inner pores of a substrate. The metal-silicide nanoparticles can be Co-silicide, Ni-silicide or Fe-silicide particles. The present invention relates also to a method to form carbon nanotubes (CNT) on metal-silicide nanoparticles, the metal-silicide containing particles hereby acting as catalyst during the growth process, e.g. during the chemical vapour deposition (CVD) process. Starting from very defined metal-containing nanoparticles as catalysts, the diameter of grown CNT can be well controlled and a homogeneous set of CNT will be obtained.

  • Patent number: 7831951
    Abstract: A system and method of designing digital system. One aspect of the invention includes a method for designing an essentially digital system, wherein Pareto-based task concurrency optimization is performed. The method uses a system-level description of the functionality and timing of the digital system. The system-level description comprises a plurality of tasks. Task concurrency optimization is performed on said system-level description, thereby obtaining a task concurrency optimized system-level description, including Pareto-like task optimization information. The essentially digital system is designed based on said task concurrency optimized system-level description. In one embodiment of the invention, the description is includes a “grey-box” description of the essentially digital system.

  • Patent number: 7803665
    Abstract: Manufacturing a semiconductor device involves forming (200) a sacrificial layer where a micro cavity is to be located, forming (210) a metal layer of thickness greater than 1 micron over the sacrificial layer, forming (220) a porous layer from the metal layer, the porous layer having pores of length greater than ten times their breadth, and having a breadth in the range 10 nm-500 nanometers. The pores can be created by anodising, electrodeposition or dealloying. Then the sacrificial layer can be removed (230) through the porous layer, to form the micro cavity, and pores can be sealed (240). Encapsulating MEMS devices with a porous layer can reduce costs by avoiding using photolithography for shaping the access holes since the sacrificial layer is removed through the porous membrane.

    Abstract: Methods and systems are described for improving optical lithographic processing of a substrate by selecting appropriate system parameters in order to obtain a good image or print of the pattern to be obtained in a resist layer, which includes selecting a set of system parameters for an optical lithographic system having selectable system parameters, thus characterising the optical lithographic system and obtaining transferred lens pupil information. The latter is performed by obtaining, for each point of a set of points within a lens pupil of the optical lithographic system with the selected set of system parameters, a value of at least one optical parameter at a level of the substrate, the at least one optical parameter being a property of a light ray projected towards the substrate from the point of the set of points within the lens pupil. The lens pupil information then is combined with information about the mask to be used for generating the pattern in the resist layer.
