The invention relates to a method for manufacturing an optoelectronic component substrate (12) comprising a stack of layers, the method comprising a step of: preforming a substrate (12) comprising a face which has a pattern with at least one zone made of a first material and one zone made of a second material, the two materials being thermosetting or thermoplastic materials, the first material being an electrically conductive material and the second material being an electrically insulating material, and molding by compression the face of the substrate (12) with a face of a reference element (22) having a surface roughness less than or equal to 50 nanometers.

A component with a customized exterior surface and a method and tool for manufacturing the same are provided. The component may be formed via a plastic forming process with a forming tool, such that it has a surface texture formed on its exterior surface. The forming tool has at least one tool surface, which defines a mold cavity. The tool surface has a textured layer coupled thereto, such that the textured layer directly contacts a moldable material supplied to the mold cavity. The textured layer has a surface texture formed thereon resulting in the surface texture present on the textured layer being transferred to and formed on the exterior surface of the component during forming. The textured layer may be changeable or replaceable with respect to the at least one tool surface, such that a single tool may form components with different surface textures formed on the exterior surface thereof.

An imprint apparatus for forming a pattern of an imprint material on a process area of a substrate by using a mold including a patterned portion includes a heating unit. The heating unit heats the substrate such that a difference in shape between the process area and the patterned portion is reduced and heats the mold such that a difference in temperature between the mold and the heated substrate is reduced.

Methods for mass production of new microfluidic devices are described. The microfluidic devices may include an array of micro-needles with open channels in fluid communication with multiple reservoirs located within a substrate that supports the micro-needles. The micro-needles are configured so as to sufficiently penetrate the skin in order to collect or sample bodily fluids and transfer the fluids to the reservoirs. The micro-needles may also deliver medicaments into or below the skin.

According to one implementation, a composite material molding jig includes a rigid portion and a convex portion for forming a groove for inserting an optical fiber sensor. The rigid portion has a surface for laminating prepreg sheets. The convex portion is formed in a surface side of the rigid portion. Further, according to one implementation, a composite material molding method is a method for molding a composite material, on which the groove for inserting the optical fiber sensor has been formed, by heating and curing a laminated body of the prepreg sheets laminated on the above-mentioned composite material molding jig.

A large area patterned film includes a first patterned area; a second patterned area; and a seam joining the first patterned area and the second patterned area, wherein the seam has a width less than about 20 micrometers. A method for tiling patterned areas includes depositing a predetermined thickness of a curable material; contacting a first portion of the curable material with a mold; curing the first portion of the curable material; removing the mold from the cured first portion of the curable material; contacting a second portion of the curable material with the mold, such that the mold contacts a portion of the cured first portion of the curable material; curing the second portion of the curable material; and removing the mold to yield a seam between the cured first portion of the curable material and the cured second portion of the curable material, wherein the seam has a dimension less than about 20 micrometers.

A method for manufacturing a molded product with fine structure includes steps of, in a temperature-controlled stamper mold provided with a fine structure including a concavo-convex pattern having a width of 10 nm to 1 μm, forming a thermoplastic molten polymer layer to be in contact with the fine structure 20 of the stamper mold having been kept at a predetermined temperature and holding the thermoplastic molten polymer layer for a predetermined time so as to transfer the fine structure of the stamper mold to the thermoplastic molten polymer layer under gravity.

A method for manufacturing a fine hollow protruding article (1) according to the invention involves: a protrusion forming step of bringing a projecting mold part (11) that includes a heating means into contact from one surface (2D) side of a base sheet (2) including a thermoplastic resin, and, while softening, with heat, a contact section (TP) in the base sheet (2) where the projecting mold part (11) contacts the base sheet (2), inserting the projecting mold part (11) into the base sheet (2), to form a protrusion (3) that protrudes from the other surface (2U) side of the base sheet (2); a cooling step of cooling the protrusion (3) in a state where the projecting mold part (11) is inserted in an interior of the protrusion (3); and a release step of withdrawing the projecting mold part (11) from the interior of the protrusion (3) after the cooling step, to form the fine hollow protruding article (1).

A needle assembly for transdermal administration including a substrate having a first surface and a second surface opposite to the first surface, and fine needles projecting perpendicularly from the first surface. The substrate has grooves on at least one of the first surface and the second surface, and the grooves are formed such that the substrate is deformable following a surface shape of a skin to allow axes of the fine needles to extend in a direction normal to the surface of the skin.
