ABSTRACT:
A method for producing the supporting structure includes pressing-in an electrically insulating ceramic material, preferably in powdered form, on substantially all sides between the structures, and shaping the structures to be both accessible, at least in partial regions, and to exert pressure from substantially all sides onto the ceramic material, without touching one another, for metallic bonding to further structures. Another method for producing the supporting structure includes joining together the structures with three-dimensional form-locking connections by joint deformation, forming a surface or a surface layer being convertible chemically into an electric insulating layer on at least one of and between the structures, and subsequently converting the convertible surface or surface layer into an electrically insulating ceramic layer, in particular by oxidation, for creating an insulating layer being pressed-in on substantially all sides between the connections.
