Abstract: An imprint lithography method is disclosed, which includes imprinting a plurality of patterns in an imprintable medium provided on a substrate, wherein the order in which the patterns are imprinted in the imprintable medium is such that, for the majority of the patterns, two consecutively imprinted patterns are not imprinted adjacent to one another.

Abstract: A synthetic jet cooling device (1) for cooling an object (5), comprising: a transducer (10) adapted to generate velocity waves, and an enclosure (4) arranged to receive the velocity waves via an actuated aperture (8). The enclosure (4) is sufficiently large to generate, at the actuated aperture (8), an internal synthetic jet inside the enclosure (4). Furthermore, the enclosure (4) is arranged to contain the object (5), thereby enabling cooling of the object (5) by the internal synthetic jet. The arrangement typically permits multifunctional use of an existing enclosure, containing the object to be cooled, both for its original purpose (e.g. a reflector in a lamp, or a LED backlight module) and as an enclosure generating internal synthetic jets, why the cooling device typically requires virtually no extra space and weight, and can be provided at a low cost.

Abstract: An imprint lithography method is provided. The method includes undertaking first and second imprints, which comprises for each imprint: for an area of a substrate provided with a plurality of drops of imprintable medium in respectively first and second configurations, imprinting a pattern in the imprintable medium using a same imprint template, pockets being formed between the drops of the imprintable medium, the imprint template and the substrate during the imprinting of the pattern, wherein the first configuration of drops of imprintable medium is different from the second configuration of drops of imprintable medium, such that pockets formed during the second imprint are formed at different locations relative to the imprint template to pockets formed during the first imprint.

Abstract: An imprint template cover for an imprint template having a pattern feature thereon. The cover is configured such that, in use, it extends around the pattern feature of the imprint template, and such that the cover does not contact the pattern feature.

Abstract: A chuck apparatus for holding a substrate is the disclosed. The chuck apparatus includes a first surface portion on which the substrate is to be held and a second surface portion adjacent to the first surface portion and extending at least partially around an edge of the first surface portion and which, in use, is arranged to deflect gas over the first surface portion and thus the substrate that is to be held on the first surface portion.

Abstract: A method of depositing an imprintable medium onto a target area of a substrate for imprint lithography is disclosed. The method includes moving the substrate, a print head comprising a nozzle to eject an imprintable medium onto the substrate, or both, relative to the other in a first direction across the target area while ejecting a first series of droplets of imprintable medium onto the substrate and moving the substrate, the print head, or both, relative to the other in a second opposing direction across the target area while ejecting a second series of droplets of imprintable medium onto the substrate on or adjacent to droplets from the first series of droplets.

Abstract: An organic electroluminescent device (41) has a plurality of independently addressable electroluminescent elements (51A, B, C, D, E, F) and comprises a patterned first electrode layer comprising a plurality of first electrodes (43A, B, C) and a second electrode layer (26A, B, C, D); an organic, optionally patterned, electroluminescent layer (25) disposed between said first and said second electrode layer; an organic charge transport layer having charge transport areas (24A, B, C, D, E, F) disposed between the first electrode layer and the organic electroluminescent layer (25); and a relief pattern (27) extending between and along neighboring first electrodes. The relief pattern separates said charge transport areas along neighboring first electrodes which has the effect of disconnecting any current path between neighboring first electrodes via the charge transport layer. Thus, the EL device has a small leakage current and can be easily manufactured.

Abstract: A method of providing a track (12) on a substrate (10) includes a first step wherein a first liquid (1) is applied to the substrate (10) in accordance with a desired double pattern (11) and, upon solidification of said first liquid, a second step wherein a second liquid (2) is applied within the double pattern (11), forming the track (12) upon solidification. The double pattern (11) laterally bounds the track (12). The liquids (1, 2) may be applied by a dispenser or an ink jet printer. The first and the second step may be carried out in one operation, wherein the application of the first liquid (1) has a lead (3) over the application of the second liquid (2). A narrow track (12) may be formed when the first liquid (1) has a head group that adheres to the substrate (10) and a tail that repels the second liquid (2).

Abstract: A substrate (22) is provided with a layer (21) comprising organo-metallic components (23) in a solvent having a high-boiling point component (24). As the solvent is removed, the high-boiling point component phase separates, forming larger globules (26) in a matrix (25). The-high-boiling point component is thereafter removed, leaving a matrix (12) of a substance such as SiO2, in which cavities (13) filled with gas or air of vacuum are present. The cavities have sizes from 5 to 200 nm.
