    Abstract: A method for manufacturing a metal microstructure (1) comprising a resin mold (13). For setting a mild manufacturing condition with little damage of the resin mold (13), and for mass−producing a high− precision metal microstructure (1) by uniform casting, this method is characterized by having the step of forming a resin mold laminate by fixing on a conductive substrate (11) a resin mold (13) having a vacancy penetrating in the thickness direction via a photosensitive polymer (12) the chemical composition of which is varied by an electron ray, ultraviolet ray, or a visible ray, the step of exposing the resin type laminate (2) to the electron ray, ultraviolet ray, or visible ray, the step of removing a photosensitized polymer (12c) present in the vacancy of the resin mold (13), and the step of filling the vacant section of the resin type laminate (2) with a metal (14) by casting.

    Abstract: The present invention describes a method for fabricating micro-devices comprising aluminumoxide structures without the need for an extra lithographical processing step. So, no extra mask is needed. It appears that under certain circumstances, aluminumoxide walls arise in the etching process, just above sloped walls of underlying metal structures. The fact that the walls of the metal structures are sloped, is essential here. Using the method according to the invention, aluminumoxide structures can be fabricated that are aligned exactly above the sloped walls of the metal structure. These aligned aluminumoxide structures can be used as walls in for example microfluidic channels, electrowetting displays, electrophoretic displays or field emitting displays.

    Abstract: The present invention relates to a method for manufacturing a micro needle array with an X-ray process. The present invention provides a method for manufacturing a micro needle array, comprising the steps of preparing an X-ray mask by forming an absorber having a configuration of the micro needle array on a substrate; preparing a PMMA cast for the micro needle array by exposing PMMA to vertical an inclined X-rays using the X-ray mask; preparing a flexible PDMS mold having a configuration opposite to that of the PMMA cast by pouring PDMS on the PMMA cast; filling an upper surface of the PDMS mold with a gel type of polymer to obtain a desired thickness of the polymer; patterning a desired configuration of a hole by irradiating UV rays on the polymer; and separating the PDMS mold to complete th polymer micro needle array. The micro needle array of the present invention is made of a polymer material and can be used for drawing blood from or injecting a medicine into the skin.
