PROBLEM TO BE SOLVED: To make easily and certainly a mold release starting point, in a pattern transfer that uses a mold. SOLUTION: The mold used for a transferring device transfers a pattern to an optical curing resin, while stiffening this optical curing resin, by bringing a mold 1 in which the pattern is formed into contact to the optical curing resin 8 on a substrate 2, and a light is irradiated. In the transfer device using this, a second region 1b is formed to the exterior of the first region 1a, in which this pattern is formed in the bottom in which the pattern in the mold, is formed. The second region is referred to as a mold release shape 1c for making a part which makes the mold, photocuring resin after curing and secession start. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
A method is provided for fabricating a fluidic module (80) comprising fluidic channels (60) defined within a glass or glass-ceramic structure. According to the method, a heterogeneous channel-forming laminate (10) is provided comprising a mold-engaging layer (20) and a laminate backbone (30). The laminate backbone (30) comprises a vitreous body defining a supportive viscosity µ B . A channel-forming mold (50) is pressed into engagement with the mold-engaging layer (20) of the channel forming laminate (10) at a molding temperature T M to form fluidic channel components (40) in the channel-forming laminate (10). The molding viscosity µ M of the mold-engaging layer (20) is less than the supportive viscosity µB of the laminate backbone (30) at the molding temperature T M . The pressed channel-forming laminate (10') is stacked with a plurality of complementary pressed channel forming laminates (10') to define a plurality of fluidic channels (60) in a stacked laminate structure (70). The plurality of fluidic channels (60) in the stacked laminate structure (70) is sealed at a sealing temperature T S that is less than the molding temperature T M and above a softening point temperature of the mold-engaging layer (20). Fluidic modules (80) comprising a stacked laminate structure (70) are also provided.

Abstract:
Disclosed herein is a microstructured tool having a microstructured layer having a polymer and a microstructured surface; a nickel layer disposed adjacent the microstructured layer opposite the microstructured surface; and a base layer disposed adjacent the nickel layer opposite the microstructured layer. The microstructured surface may have at least one feature having a maximum depth of up to about 1000 um. Also disclosed herein is a method of making the microstructured tool using laser ablation. The microstructured tool may be used to make articles suitable for use in optical applications.
Abstract:
A method is provided for manufacturing microstructures of the type which contain a substrate and an array of protruding microelements with through-holes, which are used in penetrating layers of skin. The microelements are embossed or pressed into an initial substrate structure, which in some embodiments is formed from extruded polymeric material, and in some cases from two layers of polymer that are co-extruded. The through-holes are formed from filled through-cylinders of a second material that is removed after the embossing or pressing step; in other instances, the through-holes are left hollow during the embossing or pressing step.
Abstract:
The current invention is directed to a method of patterning a surface or layer in the fabrication of a micro-device. In accordance with a preferred embodiment of the invention, a first mask structure is formed by depositing a layer of a first material onto the surface or layer and embossing the layer with a micro-stamp structure. The layer is preferably embossed as a liquid, which is solidified or cured to form the first mask structure. The first mask structure can be used as an etch-stop mask which is removed in a subsequent processing step or, alternatively, the first mask structure can remain a functional layer of the micro-device. In further embodiments, unmasked regions of the surface or layer are chemically treated through the first mask structure and/or a second material is deposited onto the unmasked regions of the surface or layer through the first mask structure to form a second mask structure and/or a second functional layer of the micro-device.
