Abstract: A method for producing an array formed from a multiplicity of electric integrated circuits, said array being intended for separation and having a conductive connection to a central contact path for bond monitoring, said method comprising the following steps: applying conductive tracks to the array, wherein the separation region is recessed from applying said tracks, and closing the conductive connection to the central contact path by applying individual conductive connection portions, which extend between two contact paths which enclose the separation region and are arranged adjacent thereto, formed from at least one material from the group comprising the elements gold, palladium, tantalum and nickel and also comprising the alloy containing predominantly at least one of the mentioned elements.

Abstract: An LTCC substrate structure with at least one contact element for connecting a wire conductor, which has a first metallization (20) arranged on and/or in the ceramic substrate for electrical connection to the wire conductor, wherein the first metallization (20) preferably contains silver or a silver alloy. To avoid via posting or a plating process, a diffusion barrier layer covering the first metallization or metal layer, which diffusion barrier layer (22) covering the first metallization (20), which diffusion barrier layer is produced with a locally acting application method, and a second metal layer (24) arranged on the diffusion barrier layer (22) are provided, wherein the second metal layer (24) preferably contains gold and/or platinum and/or an alloy that has at least one of these elements. The invention also discloses a production method for an LTCC substrate structure of this type.
