    Abstract: A method is disclosed to form a row of mutually spaced elongate lithography features along an axis on a substrate, for instance for use as contact electrodes for a NAND device. The method involves directing alignment of self-assemblable block copolymer (BCP) composition in a trench in a resist layer on the substrate, having the substrate as base, with an epitaxy feature in the trench to cause the ordered BCP layer to have elongate domains stretching across the trench width, substantially parallel to each other and to the substrate. The ordered BCP layer is then used as a resist to pattern the substrate. A BCP composition adapted to assemble with spaced discontinuous elongate elliptical domains is disclosed. The method may allow for sub-resolution contact arrays to be formed using UV lithography.

    Abstract: A method is disclosed to form a patterned template on a substrate, to direct orientation of a self-assemblable block copolymer. The method involves providing a resist layer of a positive tone resist on the substrate and overexposing the resist with actinic (e.g. UV) radiation by photolithography to expose a continuous region of the resist layer with a sub-resolution unexposed resist portion at the interface between the resist and the substrate. The resist portion remaining at the interface, after removal of the exposed region, provides a basis for a chemical epitaxy template. The method may allow for simple, direct photolithography to form a patterned chemical epitaxy template and optionally include an accurately co-aligned graphoepitaxy feature and/or a substrate alignment feature.

    Abstract: A method of forming a self-assembled block polymer layer, oriented to form an ordered array of alternating domains, is disclosed. The method involves providing a layer of the self-assemblable block copolymer on the substrate and depositing a first surfactant onto the external surface of the layer prior to inducing self-assembly of the layer to form the ordered array of domains. The first surfactant has a hydrophobic tail and a hydrophilic head group and acts to reduce the interfacial energy at the external surface of the block copolymer layer in order to promote formation of assembly of the block copolymer polymer into an ordered array having the alternating domains.

    Abstract: A method of designing an epitaxy template to direct self-assembly of a block copolymer on a substrate into an ordered target pattern involves providing a primary epitaxy template design and then varying the design to optimize a pattern fidelity statistic, such as placement error, relative to the target pattern by modelling predicted self-assembled block copolymer patterns and optimizing pattern placement as a function of a varied design parameter. In addition to varying a design parameter to optimize the pattern fidelity statistic, a random error in the template design is included prior to modelling predicted patterns in order to compensate for expected template inaccuracy in practice. The inclusion of a realistic random error in the template design, in addition to systematic variation of a design parameter, may improve the template design optimization to render the result less sensitive to error which may be inevitable in practice.

    Abstract: A method is disclosed to form a patterned epitaxy template, on a substrate, to direct self-assembly of block copolymer for device lithography. A resist layer on a substrate is selectively exposed with actinic (e.g. UV or DUV) radiation by photolithography to provide exposed portions in a regular lattice pattern of touching or overlapping shapes arranged to leave unexposed resist portions between the shapes. Exposed or unexposed resist is removed with remaining resist portions providing the basis for a patterned epitaxy template for the orientation of the self-assemblable block copolymer as a hexagonal or square array. The method allows for simple, direct UV lithography to form patterned epitaxy templates with sub-resolution features.
