    摘要: The present application provides a method of processing a substrate. The method of processing the substrate includes steps of forming a photosensitive layer on the substrate; performing a first exposure process to expose the photosensitive layer to actinic radiation through a first mask; performing a first developing process to remove portions of the photosensitive layer exposed to the actinic radiation and form an intermediate pattern; performing a second exposure process to expose the intermediate pattern to the actinic radiation through a second mask; performing a second developing process to remove portions of the intermediate pattern shielded from the actinic radiation and form a target pattern; and performing an etching process to remove portions of the substrate exposed by the target pattern.

    摘要: A pattern transfer apparatus in which a part or all of a plurality of small areas on a mask are sequentially irradiated with a charged particle beam to transfer an image of a pattern provided in each of the irradiated small areas onto a radiation-sensitive substrate, e.g., a wafer. A pattern distribution condition is evaluated for each small area, and an image-formation condition of the pattern image with respect to the radiation-sensitive substrate is adjusted for each small area on the basis of predetermined information including a result of the evaluation.

    摘要: The invention relates to a method for making a micro- or nano-scale patterned layer of material by photolitography, comprising steps of: positioning a photomask between a light source and a layer of light sensitive material, said mask comprising a support and a layer of micro- or nano-light focusing elements fixed to the support, activating the light source so that the light source emits light radiations through the mask towards a surface of the layer of light sensitive material, developing the layer of light sensitive material so as to obtain the micro- or nano-scale patterned layer of material, wherein, during exposure of the layer of light sensitive material to light radiations, the photomask is positioned relative to the light sensitive layer so that the distance between the surface of the light sensitive layer and the layer of micro- or nano-light focusing elements is greater than a back focal length of the micro- or nano-light focusing elements.

    摘要: An apparatus and method for nanopatterning of substrates using the demagnified Talbot effect, wherein: (a) large arrays of nanostructures can rapidly be printed; (b) short extreme ultraviolet wavelengths permits sub-100 nm spatial resolution; (c) the de-magnification factor can be continuously adjusted, that is, continuously scaled; (d) the patterning is the effect of the collective diffraction of numerous tiled units that constitute the periodic array, giving rise to error resistance such that a defect in one unit is averaged over the area of the mask and the print does not show any defects; (e) the Talbot mask does not wear out since the method is non-contact; and (f) the feature sizes on the mask do not have to be as small as the feature sizes desired on the target, are described. The apparatus includes a source of coherent radiation having a chosen wavelength directed onto a focusing optic, the reflected converging light passing through a Talbot mask and impinging on a target substrate.

    摘要: A device for charged particle beam lithography is disclosed which includes an inputting device, a character projection stencil and a reducing lens. The inputting device reads a set of shots, where each shot has a magnification. The character projection stencil contains a character pattern. The reducing lens introduces magnification variation of the stencil character pattern when writing the pattern onto a surface, where the magnification of the reducing lens can be varied from shot to shot.
