Classification: CPC H | IPC H

Claim 8:
9. A method for producing a carrier, comprising:
providing a main body of a material comprising a thermal conductivity of at least 380 W/(m K), wherein the main body comprises a mounting surface for mechanical and thermal connection with a component,
introducing a recess in the main body completely along a first direction perpendicular to a main extension plane of the main body,
introducing an electrically insulating filler into the recess,
introducing a further recess in the filler completely along the first direction,
coating an inner wall of the filler surrounding the further recess with an electrically conductive coating, and thereby
forming a via through the main body, Wherein providing the main body comprises:
forming the mounting surface or the main body on a protruding region of the main body along the first direction,
arranging electrically insulating material laterally to the side of the protruding region,
an inner space laterally delimited by the coating comprises a further filler, which is planarized with copper, and wherein the further filler is configured to prevent penetration of a solder into the via.
