    摘要: In an imprint method of an embodiment, in the imprinting of an imprint shot including an outermost peripheral region of a substrate where resist is not desired to be entered at the time of imprinting, light curing the resist is applied to a light irradiation region with a predetermined width including a boundary between the outermost peripheral region and a pattern formation region more inside than the outermost peripheral region, whereby the resist which is to enter inside the outermost peripheral region is cured. Then, light curing the resist filled in a template pattern is applied onto a template.

    摘要: A double patterning process is described. A substrate having a first area and a second area is provided. A target layer is formed over the substrate. A patterned first photoresist layer is formed over the target layer, wherein the patterned first photoresist layer has openings and has a first thickness in the first area, and at least a portion of the patterned first photoresist layer in the second area has a second thickness less than the first thickness. A second photoresist layer is then formed covering the patterned first photoresist layer and filling in the openings.

    摘要: Some embodiments include methods of forming patterns utilizing copolymer. A copolymer composition is formed across a substrate. The composition includes subunits A and B, and will be self-assembled to form core structures spaced center-to-center by a distance of L0. The core structures are contained within a repeating pattern of polygonal unit cells. Distances from the core structures to various locations of the unit cells are calculated to determine desired distributions of subunit lengths.

    摘要: In a method of forming a metal or metal nitride pattern, a metal or metal nitride layer is formed on a substrate, and a photoresist pattern is formed on the metal or metal nitride layer. An over-coating composition is coated on the metal or metal nitride layer and on the photoresist pattern to form a capping layer on the photoresist pattern. The over-coating composition includes a polymer having amine groups as a side chain or a branch and a solvent. A remaining portion of the over-coating composition is removed by washing with a hydrophilic solution. The metal or metal nitride layer is partially removed using the capping layer and the photoresist pattern as an etching mask.
