Abstract
An advantageous method and system for realizing electrically very reliable and mechanically extremely stable vias for components whose functionality is realized in a layer construction on a conductive substrate. The via (Vertical Interconnect Access), which is led to the back side of the component and which is used for the electrical contacting of functional elements realized in the layer construction, includes a connection area in the substrate that extends over the entire thickness of the substrate and is electrically insulated from the adjoining substrate by a trench-like insulating frame likewise extending over the entire substrate thickness. According to the present system, the trench-like insulating frame is filled up with an electrically insulating polymer.
