摘要:
Disclosed is an antioxidant fermenting microorganism agent and a polyurethane foam including the same. The antioxidant fermenting microorganism agent is used to generate a substance that is capable of reducing an amount of volatile organic compounds generated from the polyurethane foam and has an antimicrobial ability. The polyurethane foam containing the antioxidant fermenting microorganism according to the present invention can be used as the material for the interior of a vehicle to protect humans from noxious substances causing sick car syndrome.

In a method of forming fine patterns, a photocurable coating layer is formed on a substrate. A first surface of a template makes contact with the photocurable coating layer. The first surface of the template includes at least two first patterns having a first dispersion degree of sizes, and at least one portion of the first surface of the template includes a photo attenuation member. A light is irradiated onto the photocurable coating layer through the template to form a cured coating layer including second patterns having a second dispersion degree of sizes. The second patterns are generated from the first patterns and the second dispersion degree is less than the first dispersion degree. The template is separate from the cured coating layer. A size dispersion degree of the patterns used in a nanoimprint lithography process may be adjusted by the light attenuation member, so that the fine patterns may be formed to have an improved size dispersion degree.

A stencil mask includes a membrane forming thin layer having membrane areas and a border area that limits the membrane areas. The membrane areas have a plurality of pattern areas which include an aperture through which particle beams can permeate and non-pattern areas interposed between the pattern areas. A main strut supports the membrane areas and is formed on the border area of the membrane forming thin layer. An auxiliary strut is formed in the non-pattern areas inside the membrane pattern area such that the auxiliary strut divides the membrane areas into plural divided membrane areas. The auxiliary strut supports the divided membrane areas.
摘要:
A photomask includes a transparent substrate, and a plurality of light-shielding patterns repeatedly aligned on the transparent substrate in two dimensions. Each of the light-shielding patterns has length and width measurements that differ from each other. Further, the photomask includes at least one through hole penetrating a portion of each of the light-shielding patterns to expose the transparent substrate.
