Abstract:
A self-supporting contacting structure is directly produced on a component that does not have a housing by applying a layer made of nonconducting material and a layer made of an electrically conductive material to the component and to a support and by subsequently removing these layers from said support.
Abstract:
According to the invention, a layer made of an electrically insulating material (3) is applied to a substrate (1) and a component (2) that is arranged thereupon in such way that said layer follows the surface contour formed by the substrate and the component.
Abstract:
The invention relates to a method for contacting electrical contact surfaces (21, 112) on a surface (20) of a substrate (1). According to said method, a film (3) based on polyimide or epoxy is laminated onto the surface, under a vacuum, in such a way that the film closely covers the surface comprising the contact surfaces and adheres to the same. Each contact surface to be contacted on the surface is uncovered by opening respective windows (31) in the film, and a contact is established in a plane manner between each uncovered contact surface and a layer (4) of metal. The inventive method is used to establish a large-surface contact for power semiconductor chips, enabling a high current density.

The invention relates to a method for producing a device comprising a component (2) that is located on a substrate (1). The substrate (1) and component (2) form a surface contour and the component (2) comprises an electrical contact surface (210). According to said method: a layer (3) of electrically insulating material is applied to the substrate (1) and the component (2) located thereon, in such a way that said layer (3) follows the surface contour formed by the substrate (1) and the component (2); the electrical contact surface (210) of the component remains at least partially uncovered during the application of the layer (3) of electrically insulating material and/or is exposed after the application of said layer (3); and a layer (4) of electrically conductive material is applied to the layer (3) consisting of electrically insulating material and the electrical contact surface (210) of the component.

The invention relates to a circuit arrangement (1) placed on a substrate (2) and comprising at least one semiconductor component (3) arranged on the substrate and having at least one electrical contact surface (31) and at least one connection line (4) also arranged on the substrate and used to electrically contact the contact surface of the semiconductor component. Said circuit arrangement is characterised in that the connection line (4) forms part (51) of a discrete, passive electrical component (5) arranged on the substrate (2). The electrical contacting of the contact surface (31) of the semiconductor component is carried out during a step of the process and the part (51) of the discrete, passive electrical component (5) is produced. To this end, especially a film consisting of an electrically insulating material is applied to the semiconductor component (3) embodied as a power semiconductor and to the substrate (2) under a vacuum, and the contact surface of the power semiconductor is then bared. Furthermore, the connection line (4) is produced, whereby the electrical contacting of the contact surface (31) of the semiconductor component is carried out and the part (51) of the discrete, passive electrical component is produced.

The present invention discloses various production methods for producing a piezoceramic multilayer actuator. In the course of the production method, multilayer locks (10) are electrochemically or mechanically processed in such a way that a recess structure is obtained. The lateral surfaces (22; 24) of the electrodes (20) inside these recesses are electrically insulated using the slip casting method in order to be able to contact the remaining electrodes by imprinting an outer metallization.

The invention relates to a three-dimensional micro-structure comprising a plurality of adjacent micro-columns which are arranged at a distance from each other and essentially parallel in relation to the respective longitudinal extension, said micro-columns being made of at least one micro-column material having respectively an aspect ratio in the region of 20 - 1000 and respectively a micro-column diameter in the region of 0,1 µm - 200 µm, and a micro-column intermediate chamber arranged between adjacent micro-columns having a micro-column distance selected from between the adjacent micro-columns in the region of 1 µm - 100 µm. The invention also relates to a method for producing the three-dimensional micro-structures according to the following steps: a) a template is provided with template material, said template having a three-dimensional structure with column-like template cavities essentially inverse for the micro-structure, b) the micro-column material is arranged in the column-like cavities such that the micro-columns are formed, and c) the template material is at least partially removed. A silicon wafer is preferably used as the template. In order to provide the template, the PAECE (Photo Assisted Electro-Chemical Etching) method is used. Said invention enables micro-structures with extremely large surfaces to be produced.
