Abstract: This invention relates to a method for forming a patterned layer on a substrate by means of an imprint process. According to the method a first layer is provided on the substrate, and a pattern of recesses is provided in the first layer by imprinting the layer with a patterning means. Then the first layer is cured. The curing is followed by performing a first surface treatment onto the first layer to make the surface of thereof hydrophilic, and then performing a second surface treatment onto a selected subarea of the surface of the first layer to make the. subarea hydrophobic. The subarea includes surface portions between the recesses and excludes the recesses. Finally, a conducting pattern material (41) is deposited into the recesses.

Abstract: The invention provides a method and apparatus for laminating a sheet to a substrate in a stress free and distortion-less manner. The method comprises providing the sheet and substrate such that an attractive force between them exists that is capable of bringing the sheet and surface together at least when their distance is shorter than a critical distance. The method creates these conditions by locally making an initial contact between the sheet and substrate such that at a contact front, being the boundary between areas where the substrate and sheet are in contact and those where they are not in contact, these conditions exist. In a further step the sheet and substrate are allowed to gradually make contact such that the contact front advances along either of the substrate or sheet surface therewith increasing the contacting area between the substrate and the sheet.

Abstract: The invention relates to a method for forming a relief layer (216) employing a stamp (206) having a stamping surface (208) including a template relief pattern. A solution comprising a siliconoxide compound (200) is sandwiched between a substrate surface (202) and the stamp surface (208) and dried while sandwiched. After removal of the template relief pattern the relief layer obtained has a high inorganic mass content making it robust and directly usable for a number of applications such as semiconductor, optical or micromechanical.

Abstract: A method for the production of a light emitting device is provided, comprising providing at least one LED 10 and at least one optical element 13; arranging a bonding material 12, comprising a stable colloidal sol of inorganic metal oxide nanoparticles dispersed in a liquid medium, on a light emitting surface 11 of said at least one LED and/or on a surface of said at least one optical element 13; (c) placing said at least one optical element 13 on the light emitting surface 11 of said at least one LED 10 with said bonding material 12 there between to form at least one assembly; and curing said bonding material to form an inorganic bond. The bonding material may be cured at temperatures not detrimental to the LED, while the resulting bond is photo-thermally stable.

Abstract: The invention relates to a method for contacting a flexible sheet to a first element with improved lateral alignment. The method includes a step of measuring a first lateral misalignment after establishing a first contact between the flexible sheet and either of the first element and a sheet parking surface called anchor in the first stage. If the 5 misalignment exceeds a predetermined threshold the flexible sheet is parked at the anchor such that it is not in contact with the first element, and the relative position of the first element and the anchor is altered during the second stage for correcting the mismatch during a contact between the flexible sheet and the first element to be established within the next step of the method. During the steps of shifting the contact point to obtain the second stage 10 the contacting process is more accurate and reproducible than the process for establishing the initial contact.

Abstract: An inorganic phosphor body (102) for a light emitting diode, comprising an inorganic luminescent material is provided. A bonding precursor material (103) is arranged on a surface of said inorganic phosphor body (102), and the bonding precursor material comprises an at least partly hydrolyzed organically modified silane. The attachment of the bonding precursor material to the inorganic phosphor body is separated from the bonding of the inorganic phosphor body to a light emitting diode. Thus, the attachment of the bonding precursor material to the inorganic phosphor body may be performed at conditions detrimental to the LED.

Abstract: The matching of refractive index of a nanoporous membrane with an analyte solution used with the membrane for use in a sensor is described. Scattering of the excitation and/or emitted light is reduced by matching the refractive indices. This improves efficiency when the porous translucent membrane is used in flow-through or flow-over sensors such as biosensors.
