1-15. (canceled)
A carrier device for an electrical component, the carrier device comprising:
- a carrier comprising an electrically insulating layer;
- and
- an electrical contact layer overlying the electrically insulating layer;
- wherein the electrical contact layer comprises a ridge-shaped contact region;
- and
- wherein a recess is arranged in the electrically insulating layer at least at one side surface of the ridge-shaped contact region or wherein the ridge-shaped contact region has a ridge width that decreases toward the electrically insulating layer.
A method for producing a carrier device, the method comprising:
- (A) providing a carrier comprising an electrically insulating layer;
- (B) forming an electrical contact layer over the electrically insulating layer, the electrical contact layer having a ridge-shaped contact region;
- and
- (C) forming a recess in the electrically insulating layer by at least partly removing the electrically insulating layer at least at one side surface of the ridge-shaped contact region or forming a ridge width of the ridge-shaped contact region which decreases toward the insulating layer.
A carrier device for an electrical component, the carrier device comprising:
- a carrier comprising an electrically insulating layer;
- and
- an electrical contact layer on the electrically insulating layer;
- wherein the electrical contact layer comprises at least one ridge-shaped contact region;
- wherein at least one recess is arranged in the electrically insulating layer at least at one side surface of the ridge-shaped contact region;
- wherein the ridge-shaped contact region has a ridge width that decreases toward the electrically insulating layer;
- and
- wherein the carrier device is embodied as a circuit board, a metal core circuit board, a ceramic carrier, a glass carrier, a glass ceramic carrier or an anodically oxidized carrier.
