Abstract:
The invention relates to a lithographic method for producing microcomponents having a submillimeter structure, whereby the resist material can be dissolved in a simple manner. According to the invention, a structurable adhesive layer is applied to a metallic starting layer, a layer consisting of photostructurable epoxy resin is applied to the adhesive layer, and the epoxy resin is structured by means of selective illumination and dissolution of the unexposed regions in order to create supporting structures and free spaces between the supporting structures. Only the free spaces provided for the microcomponent and located between the epoxy resin supporting structures are then filled with metal according to a galvanic method, and the epoxy resin is removed, the remaining free spaces being filled with etching agents.
Abstract:
The invention relates to a method for producing a device (120) having a three-dimensional magnetic structure (132), comprising a step of applying magnetic particles (130) onto or into a carrier element (122), wherein a plurality of hollow spaces that are at least partially connected to one another are formed between the magnetic particles, and wherein the magnetic particles are brought into contact with one another at contact points. The method also comprises a step of joining the magnetic particle at the contact points by coating the assembly formed by magnetic particles and the carrier element, wherein the hollow spaces are penetrated at least partially by the layer generated by the coating. The device comprises a conductor loop assembly (124) on the carrier element or a further carrier element, such that in the event of a current flow through the conductor loop assembly (1), an inductivity of the conductor loop assembly is altered by the three-dimensional magnetic structure, or (2) a force acts on the three-dimensional magnetic structure or the conductor loop assembly via a magnetic field generated by the current flow, or (3) in the event of a change of position of the three-dimensional magnetic structure, a current flow is induced via the conductor loop assembly.

Abstract:
The invention relates to a method of making a three-dimensional structure in semiconductor material. A substrate (20) is provided having at least a surface comprising semiconductor material. Selected areas of the surface of the substrate are to a focused ion beam whereby the ions are implanted in the semiconductor material in said selected areas. Several layers of a material selected from the group consisting of mono-crystalline, poly-crystalline or amorphous semiconductor material, are deposited on the substrate surface and between depositions focused ion beam is used to expose the surface so as to define a three-dimensional structure. Material not part of the final structure (30) defined by the focused ion beam is etched away so as to provide a three-dimensional structure on said substrate (20).
