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:
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.
Abstract:
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.

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:
A method for selectively producing film laminates for packaging and for insulating unpackaged electronic components and functional patterns and corresponding device. The present invention relates to a method for coating surface regions (2) of functional patterns (5) arranged on a substrate (4) and/or of surface regions (2) of semiconductor chips (6) arranged on the substrate (4). An insulation is to be effectively adapted in its properties to different requirements of functional patterns (5) and/or electronic components (6). Film regions (1) are laminated on surface regions (2) in such a way that the properties of the plastics material of the film regions (1) are adapted to the function of the film. This adaptation is individual and selective. Various films (3) are used. The method is suitable in particular for coating or packaging electronic components (6) or active and passive devices.
Abstract:
The invention relates to the assembly of an electrical component (3) on a substrate (2). At least one electrical insulation film (5) is provided to electrically insulate the component and at least one section (52) of the insulation film is connected to the component and the substrate, in such a way that the surface contours (51) of said section of the insulation film are moulded to the surface contours (11) formed by the component and the substrate. The assembly is characterised in that the insulation film (5) has a dielectric strength in relation to an electric field strength of more than 10 kV/mm and preferably more than 50 kV/mm. To produce the assembly, the insulation film is laminated onto the substrate, preferably by means of a vacuum. This ensures that the insulation film and the component are in extremely close contact. The component is in particular a power semiconductor component. The insulation film ensures that no electrical arcing takes place, despite the high electrical voltages used during the operation of components of this type, even on exposed parts of the component, i.e. corners or edges, in which field overshoots can occur.
Abstract:
The invention relates to an arrangement (1) of an electrical component (3) placed on a substrate (2), at least one film (5) comprising a plastic material being provided and at least one part (52) of the film being connected to the component and to the substrate in such a way that a surface contour (11) defined by the component and the substrate is represented in a surface contour (51) of the part of the film. Said film is laminated onto the component and the substrate in such a way that the film follows the topology of the arrangement consisting of the component and the substrate. Said film is in contact with the component and the substrate in a positive and non-positive manner, and comprises a composite material containing a filler that is different to the plastic material. The processability and the electrical properties of the film are influenced by the filler or the composite material obtained thereby. In this way, other functions can be integrated into the film. Said component is, for example, a power semiconductor component. An electrically insulating and thermoconductive film is used, for example. A contact surface of the power semiconductor component is electrically contacted through the film. The thermal conductivity of the film enables heat created during the operation of the power semiconductor component to be efficiently carried away.
