Abstract:
A device is provided for transferring a pattern to an object. The device may be used for transferring a pattern, such as micro- or nanostructures, from a stamp to an object. In accordance with one embodiment, the device comprises a first contacting means with a receiving surface for the stamp and a second contacting means with a receiving surface for the object. The device may further include a pressing means that is adapted to operate at least one of the contacting means for contacting the stamp with the object. One of the contacting means may include a base and a holder. The holder has a first end which defines one of the receiving surfaces and a second opposite end which is pivotally connected to the base in such a manner that the stamp and the object are automatically placed in a parallel position when contacting each other.
Abstract:
A metal mold for use in a nano-imprinting process comprises a firmly adhering monomolecular non-sticking layer. The layer was obtained by subjecting the mold to a reaction with a fluoroalkyl compound having a mercapto group. As a result of said reaction, the layer comprises an organic sulfide of said metal.
Abstract:
A device for homogeneous heating of an object comprises a supporting surface for supporting the object, and a heating layer arranged on the supporting surface. The heating layer absorbs at least partly energy received from a radiation source and emits at least partly the thus-absorbed energy to the object supported on the supporting surface. The layer is made of a material such that the energy absorbed by the layer is in a self-regulating manner distributed uniformly along the surface of the layer. The heating device forms a simple and compact unit which can be used to rapidly heat the object to a homogeneous temperature.
Abstract:
The present invention relates to an arrangement (1) for detection of a first resonance frequency (F1), related to a mass (1b′) loaded carrier means (1b), and to compare said first resonance frequency (F1) with a second, as a reference used, resonance frequency (F2), related to said carrier means (1b), by using frequency comparing and/or calculating means (3, 4) to evaluate, by a noted frequency shift (F2-F1), a mass weight (1b′). An array of individual carrier means (1a, 1b . . . 1i) are arranged adjacent to each other, that one or more of said carrier means are allotted different second resonance frequencies, that received resonance frequencies (F1) from said loaded carrier means are received and/or evaluated simultaneously, or at least essentially simultaneously, in a signal receiving and/or processing unit (3) and that said first resonance frequencies (F1) are compared and/or calculated within said calculating means (3, 4) with corresponding resonance frequencies (F2) stored in said unit (3, 4) in a memory (4b) thereof.

A method for replicate a pattern from a pre-patterned surface to a final substrate with in parallel approach lithography, the pre-patterned surface comprises a transparent substrate having a pre-patterned suitable metal; the method comprising the steps of: covering the final substrate with a chemical composition (resist) that is sensitive to Plasmon emitted light or waves; bringing the pre-patterned surface and the final substrate together to a proximity distance in the nanometer range, preferably 0 to 30 nm or more preferably 0 to 10 nm from the surface; illuminating the pre-patterned surface with plasmonic emitted light or waves, and exposing the final substrate to the plasmonic emitted light or waves to make a replica from the said pre-patterned surface.
Abstract:
Method for manufacturing a mold tool (1), devised for forming a structured nanoscale pattern on an object (24) and having a layer (16) which is anti-adhesive with regard to the object (24). A stamp blank (2) is provided with a structured pattern (4) on a surface (8). The patterned surface (8) is coated with a layer (6) of a metal, which has a stable oxidation number and can form a mechanically stable oxide film. The metal layer (6) is oxidized for forming of an oxide film (10). The oxide film (10) is exposed to a reagent comprising molecule chains (18), each of which has a linkage group (20) which bonds to the oxide film (10) by chemical bonding, wherein the molecule chains (18) either at the outset comprise at least a group (22) comprising fluorine, or in a subsequent step is provided with at least one such group (22).
Abstract:
An imaging system/camera consisting of multiple nano-sized optical elements arranged in an array format with more than one pixel per optical element will have a higher resolution than each element would be capable of individually, since each element being at a different point gathers slightly different overlapping information. Hence by processing such information one can obtain a clear image. Furthermore multiple information from sectors of an array of sensors can be processed to obtain 3-D, stereotypic and panoramic imaging and may be connected to each other allowing seeing around obstacles as well as enabling full 3-D tracking and/or metric determination of an unknown object. Color/spectroscopic imaging can be achieved by utilizing equally sized lenses and multi-wavelength sensing layers below the lenses. However, color/spectroscopic imaging and/or spectroscopy can be achieved by taking advantage of unique optical properties of nano-scaled lenses accepting various wavelengths below their diffraction limits.
Abstract:
Method, apparatus and stamp for aligning a first surface (11) of a first object (10) with a second surface (22) of a second object (20), facing said first surface, wherein light of a predetermined wavelength is introduced into one (10) of said objects and caused to propagate by internal reflection therein. The first and second surfaces carry correlating structures (13,25) which, when arranged at close distance from each other, couple light from said one object to the other of said objects by near-field tunneling, to a degree dependent on the overlap of said structures. A light detector (26) is devised to detect a signal which is dependent on the amount of light coupled between said objects, for producing an alignment control signal. The invention is suitable for use in nanoimprint lithography.

The present invention refers to an arrangement adapted to evaluate the spectral intensity of and/or a changing in the spectral intensity of an electro-magnetic beam or a bundle of beams, whereby said bundle of beams is directed towards and received by a lens element and where said lens element is adapted to direct said bundle of beams towards a multitude of electro-magnetic beam to an electric signal transforming means, named as an opto-electric transforming means, said means adapted to generate an electric signal representative to said spectral intensity of or said changing in said spectral intensity of said beam. The invention suggests that a multitude of lens elements shall expose dimensions adapted within a sub-micron scale (10−6 m) and that at least one of said opto-electric transforming means, preferably a multitude of said means, is arranged adjacent to said lens element.
