Classification: CPC H | IPC H

Claim 9:
10. A component comprising:
a first component part;
a second component part; and
a through-via,
wherein the first component part has a first insulation layer and the second component part has a second insulation layer,
wherein the through-via is an AuSn alloy and electrically conductively connects the first component part to the second component part,
wherein the through-via is arranged in a first opening of the first insulation layer and in a second opening of the second insulation layer, and is completely enclosed in lateral directions by both the first insulation layer and the second insulation layer,
wherein the through-via is an AuSn eutectic which is formed in one piece,
wherein the first and second openings form a common closed cavity,
wherein, at least in places, the common closed cavity has a larger lateral extent than the through-via so that the through-via only partially fills the common closed cavity,
wherein intermediate spaces are located between the through-via and inner walls of the common closed cavity, the intermediate spaces being filled with a gaseous medium,
wherein the first insulation layer and the second insulation layer comprise SiO2,
wherein the first insulation layer and the second insulation layer form a common interface, the common interface being free of a connecting material, and
wherein side surfaces of the through-via have a positive curvature in some areas and a negative curvature in other areas.
