Abstract: A method of making an imprint template includes providing a transfer layer on a substrate and providing a layer of imprintable medium on the transfer layer, using a master imprint template to imprint a pattern into the imprintable medium, polymerizing the imprintable medium by exposing it to actinic radiation, then etching the resulting polymer layer, the transfer layer and the substrate such that the imprinted pattern is transferred to the substrate, the substrate thereby becoming an imprint template bearing a pattern which is the inverse of a pattern provided on the master imprint template.

The apparatus has a substrate table configured to support a lithographic substrate and a plurality of nozzles arranged to eject fluid onto the lithographic substrate, the plurality of nozzles extending over a distance which is substantially equal to or greater than a width of the substrate, wherein the nozzles, the lithographic substrate, or both, are moveable relative to the other.

Abstract: A method of making a substantial replica of a first imprint template which bears a first pattern is disclosed. The method includes filling recesses of the first pattern with a first material, removing the first material from the first imprint template to form a second imprint template which bears a second pattern, the second pattern being the substantial inverse of the first pattern, filling recesses of the second pattern with a photo-curable medium, curing the photo-curable medium by illuminating it with radiation, and removing the cured medium from the second imprint template to form a third imprint template which bears a pattern that is a substantial replica of the first pattern.

Abstract: During the manufacture of PoIyLED displays, printed elements of the LEDs are obtained by first printing bottom element layers (23a) and subsequently printing top element layers, according to a predetermined pattern. When the dimensions of a PoIyLED display are relatively large, the printing process of each layer (23a) takes place in several strokes. In order to prevent a situation in which unacceptable differences in the height distribution of the obtained elements exist, the layers (23a) of elements which are located at a circumference of a group of elements associated with one printing stroke are printed in two steps. During a first printing stroke, a first portion of the element layers (23a) is printed, whereas during a subsequent printing stroke, the remaining portion of the element layers (23a) is printed. Consequently, the printing strokes are performed in an overlapping manner.

Abstract: A method of aligning an imprint template with respect to a target region of a substrate is disclosed, the method including depositing a volume of an imprintable medium within the target region; contacting an imprint template to the imprintable medium so that the imprintable medium is compressed and allowing the imprint template, the target region, or both, to move laterally with respect to each other under interfacial tension forces between the target region and the imprint template, wherein a material which is less wetting than the substrate is provided in a configuration which at least partially surrounds the target region of the substrate.

The invention further provides a lead frame arranged for use in such a method, a lead frame band comprising at least one such lead frame, and an optical reading and/or writing head and an optical reading and/or writing device.

Abstract: A lithographic apparatus is disclosed that has an imprint template or a template holder configured to hold an imprint template, and a substrate table arranged to receive a substrate, the apparatus further comprising walls which together with the substrate table and the imprint template or the template holder, are configured to form an enclosed space which is substantially sealed from a surrounding area.

Abstract: A method for controlling printing actions of a print head (1) comprising pumps (10) filled with ink (18), and actuators (16) for generating actuation pulses acting on the ink (18), comprises the step of determining a characteristic frequency of the pumps (10). As the characteristic frequency of the pumps (10) is directly related to the geometry of the pumps (10), the characteristic frequency can be used as an indicator of the state of the pumps (10) and the volume of the ink droplets emitted by the pumps (10). In case a slight change of the characteristic frequency is detected, the actuation pulse is adjusted in order to still meet the requirements regarding the volume of the ink droplets. In case a relatively large change of the characteristic frequency is detected, the printing action of the pump (10) concerned is stopped, and may be taken over by another pump (10).

Abstract: The present invention provides a matrix substrate for controlling liquids printed on the substrate and a method of fabrication of such. According to the invention, a substrate holding a matrix of pixels for receiving and holding printed liquids is fabricated in a deformable and flexible polymeric material which allows for raised structures (barriers) separating the pixels to be formed in the substrate material itself. This renders possible a number of new methods of fabrication for the fabrication of matrix substrates, e.g. for use in polyLED displays. The materials and methods of fabrication according to the invention further remove a number of limitations in the freedom of design known from materials and methods of fabrication according to the prior art. This leads to the possibility of barrier profiles with overhanging structures, improved resolution and new dimension ranges.
