Abstract:
Die Erfindung betrifft ein Verfahren zum Herstellen einer Vielzahl plattenförmiger Mikrostrukturkörper aus Metall, bei dem durch wiederholtes Abformen eines die Mikrostrukturen aufweisenden Werkzeugs mit einer elektrisch isolierenden Abformmasse Negativformen der Mikrotrukturen erzeugt werden, die galvanisch mit einem Metall aufgefüllt werden, wonach die Negativformen entfernt werden, und bei dem die elektrisch isolierende Abformmasse mit einer elektrisch leitenden, als Elektrode für die Galvanik dienenden Schicht verbunden wird, wobei die Dicke der elektrisch isolierenden Abformmasse der Höhe der herzustellenden Mikrostrukturen entspricht. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art so zu gestalten, daß der Herstellungsaufwwand verringert und damit bessere Voraussetzungen für eine Massenherstellung geschaffen werden. Zur Lösung schlägt die vorliegende Erfindung vor, daß vor dem Abformen eine Schicht (31) aus der elektrisch isolierende Abformmasse mit der Schicht (3) aus elektrisch leitender Abformmasse verbunden wird, und daß das Werkzeug (31) soweit in die Schicht (31) aus der elektrisch isolierenden Abformmasse eingedrückt wird, bis die Stirnflächen (33a) der Mikrostrukturen (33) des Werkzeugs (31) die Schicht (30) aus elektrisch leitender Abformmasse berühren.
Abstract:
PURPOSE: A complex micro-machine component and a manufacturing method thereof are provided so that directional etching is done on the whole horizontal parts of coated portion and thus an insulating layer exists only on one or more cavities and the outer walls of a part. CONSTITUTION: A manufacturing method of a complex micro-machine component comprises following steps. A substrate, which comprises a horizontal top layer(21) and a horizontal bottom layer is prepared. One or more patterns are etched in the top layer through a middle layer(22). The upper part of the substrate is coated with electric insulating coating agent. Directional etching is done on the coated layer and the middle layer and thus a layer exists only on each vertical wall, which is formed in the top layer. An electrode is connected to the conductive bottom layer of the substrate and electric deposition is performed. A complex component is released from the substrate.

PURPOSE: A preparation method of a microneedle array of polymer material using a LIGA(LIthographie, Galvanoformung, Abformung) process is provided to enhance a production efficiency and to use a polymer harmless to a human body. CONSTITUTION: The preparation method of a microneedle array(15) of a polymer material comprises the steps of: preparing an X-ray mask by forming an absorber having a microneedle array structure on a silicon substrate; preparing a microneedle array PMMA frame by exposing X-ray vertically or slantwise on the PMMA using the X-ray mask; preparing a flexible PDMS die by pouring PDMS on the PMMA frame; charging a gel type polymer on the die and forming in a determined thickness; irradiating the polymer with UV and shape-etching a whole in a determined shape; and completing a microneedle array of a polymer material by detaching the die.
