Patent ID: 8025782

Claim:
A process for fabricating simultaneously a plurality of monolayer or multilayer metal structures in LIGA technology, comprising, in sequence: depositing a photoresist layer on a flat bulk metal substrate, creating a plurality of photoresist molds by irradiation or electron or ion bombardment, electroplating a metal or alloy in these molds to form electroformed metal structures, carrying out one or more machining operations on the upper face of the electroformed metal structures, detaching the electroformed metal structures and the photoresist layer from the substrate, and separating the photoresist from these metal structures, wherein the bulk metal substrate on which the photoresist layer is deposited is a passivated bulk metal substrate for separating the metal structures and the photoresist from the bulk metal substrate by delamination, wherein a positioning member is fastened to the substrate before forming said electroformed metal structures, wherein the positioning member positions an insert on said substrate, wherein said insert is removably associated with said positioning member, wherein said positioned insert becomes attached to said electroformed metal structures when said electroformed metal structures are formed, and wherein the electroformed metal structures are detached from the substrate together with said insert attached to the metal structures and the photoresist layer, so that the obtained metal structures have the positioned insert attached thereto.
