Abstract:
[Objective] To enable predictions of wet spreading and unions of a plurality of droplets in a simple manner, even in the case that the plurality of droplets are in contact with a patterned surface that causes anisotropy in wet spreading. [Constitution] A simulation method predicts wet spreading and unions of a plurality of droplets (6) arranged on a patterned surface (P) defined by a fine pattern (1) of protrusions and recesses, the patterned surface (P) causing anisotropy to occur in the wet spreading of the droplets (6). The influence imparted by the pattern (1) of protrusions and recesses that defines the patterned surface (P), which is the target of analysis, on the wet spreading of the droplets (6) is treated as wetting properties of an analysis surface (A), and the wet spreading and unions of the plurality of droplets (6) on the analysis surface (A) are analyzed by gas liquid two phase flow analysis that incorporates the wetting property parameters that represents the wetting properties.
Abstract:
[Objective] To realize pressing of a mold against a surface coated with curable resin at a uniform pressure to suppress the generation of fluctuations in residual film, in nanoimprinting that employs a mesa type mold and/or a mesa type substrate. [Constitution] In a nanoimprinting method, an assembly (8), of which the entire surface is directly exposable to the environment, is supported by a pressure vessel (110) by a support member (140) such that fluid pressure (P) from the environment operates on the entire surface of the assembly (8). Gas is introduced into the pressure vessel (110), and fluid pressure (P) exerted by the gas presses a mold (1) and a substrate (7) against each other.
Abstract:
[Objective] To remove foreign particles adhered to molds efficiently and at low cost. [Constitution] A position (P1) on a mold (1), at which a foreign particle (F) is present is detected, and adhered position information related to the position (P1) is obtained. Corresponding position information related to a position (Q1) on a substrate (2), which is a position that corresponds to the position (P1) when a pattern (13) of protrusions and recesses and a surface of the substrate (2) on which acurable composition is coated face each other and undergo a predetermined positioning operation, is generated based on the adhered position information. At least one droplet (Da) of the curable composition is arranged at the position (Q1) of the substrate. The pattern (13) of protrusions and recesses is pressed against the surface of the substrate (2) on which the composition is coated while administering the predetermined positioning operation. The curable composition is cured, and the mold (1) is separated from the cured composition.
Abstract:
[Objective] To suppress the collapse of the end portions of protrusions of a pattern on curable resin when a mold is pressed against the curable resin on a substrate then separated therefrom, in nanoimprinting that employs a mold having a predetermined fine pattern of protrusions and recesses on the surface thereof. [Constitution] A nanoimprinting mold has a fine pattern (13) of protrusions and recesses constituted by a plurality of linear protrusions (14) and a plurality of recesses (15) on the surface thereof. The pattern (13) of protrusions and recesses includes at least one recess (15) having an end portion (15a) of a predetermined shape. The predetermined shape is that which has a cross section with a smaller aspect ratio than an aspect ratio of a cross section of a connecting portion (15b), which is a portion of the recess (15) having the end portion (15a) other than the end portion (15a) and continuous therewith.
