    Abstract: A method for calibrating a resist model. The method includes: generating a modeled resist contour of a resist structure based on a simulated aerial image of the resist structure and parameters of the resist model, and predicting a metrology contour of the resist structure from the modeled resist contour based on information of an actual resist structure obtained by a metrology device. The method includes adjusting one or more of the parameters of the resist model based on a comparison of the predicted metrology contour and an actual metrology contour of the actual resist structure obtained by the metrology device.

    Abstract: A method is disclosed for forming a row of mutually spaced lithography features on a substrate, such as contact electrodes for a NAND device. The method involves forming and/or using a narrow slot over the substrate defined between the edge of a hard mask layer and a side wall of a trench in a resist layer overlying the edge and the substrate. A self-assemblable block copolymer is deposited and ordered in the trench for use as a further resist for patterning the substrate along the slot. The method allows for a sub-resolution contact array to be formed using UV lithography by overlapping the trench with the hard mask edge to provide the narrow slot in which the contact electrodes may be formed.

    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.
