Component carrier and component carrier arrangement
View Patent ↗A component carrier includes a multi-layer carrier body having a substrate containing a structured functional. The substrate extends both laterally and also at least partially above and below the functional region. Alternatively, or in addition, the substrate extends both laterally and also completely above and/or below the functional region. Alternatively, or in addition, the substrate or a further region is arranged in or extends into the functional region.
1. A multilayer carrier body comprising:
a first three dimensional structure having six side faces;
a second three dimensional structure covering five of the six side faces and leaving one side face exposed; and
a layer structure covering the second three dimensional structure except for the one side face of the first three dimensional structure and a side face of the second three dimensional structure adjacent to the one side face,
wherein the second three dimensional structure comprises stacked films with a metallic material,
wherein the layer structure comprises a first ceramic, and
wherein the first three dimensional structure comprises a material different than the first ceramic and the metallic material.
2. The multilayer carrier body according to claim 1 , wherein the second three dimensional structure has an increased thermal conductivity compared to the layer structure.
3. The multilayer carrier body according to claim 1 , wherein the layer structure comprises Al 2 O 3 or Al 2 O 3 and glasses.
4. A component carrier comprising:
a multilayer carrier body according to claim 1 ; and
a heat sink element located at an underside of the multilayer carrier body.
5. The component carrier according to claim 4 , further comprising an insulation layer located at a surface of the multilayer carrier body.
6. The multilayer carrier body according to claim 1 , wherein the second three dimensional structure comprises metallic layers.
7. The multilayer carrier body to claim 1 , wherein the material is a second ceramic.
8. The multilayer carrier body according to claim 1 , wherein the first three dimensional structure has a parallelepiped structure.
9. The multilayer carrier body according to claim 1 , wherein the first three dimensional structure is directly adjacent to the second three dimensional structure.
10. The multilayer carrier body according to claim 9 , wherein the second three dimensional structure is directly adjacent to the layer structure.
