Abstract
The present invention relates to a multilayer ceramic board and manufacturing method thereof. The multilayer ceramic board includes: a ceramic stacked structure in which multiple ceramic layers are stacked and interconnected to one another through vias; diffused reflection preventing patterns which expose the vias provided on each of the uppermost ceramic layer and the lowermost ceramic layer, and are disposed on each of a top surface and a bottom surface of the ceramic stacked structure; and contact pads which are electrically connected to the vias exposed by the diffused reflection preventing patterns.
Claims18
A multilayer ceramic board comprising:
- a ceramic stacked structure in which multiple ceramic layers are stacked and interconnected to one another through vias;
- diffused reflection preventing patterns which expose the vias provided on each of the uppermost ceramic layer and the lowermost ceramic layer, and are disposed on each of a top surface and a bottom surface of the ceramic stacked structure;
- and
- contact pads which are electrically connected to the vias exposed by the diffused reflection preventing patterns.
A method of manufacturing a multilayer ceramic board comprising:
- providing a ceramic stacked structure in which multiple ceramic layers are stacked, and are interconnected to one another through vias;
- forming diffused reflection preventing patterns which expose the vias provided on each of the uppermost ceramic layer and the lowermost ceramic layer, and are disposed on each of a top surface and a bottom surface of the ceramic stacked structure;
- and
- forming contact pads which are electrically connected to the vias exposed by the diffused reflection preventing patterns.
A method of manufacturing a multilayer ceramic board comprising:
- providing a ceramic stacked structure in which multiple ceramic layers are stacked;
- stacking green sheets which have vias playing a role of performing interlayer connection between the ceramic stacked structure, and the diffused reflection preventing patterns on each of both sides of the ceramic stacked structure;
- firing the ceramic stacked structure in which the green sheets are stacked;
- and
- forming contact pads electrically connected to the vias exposed by the diffused reflection preventing patterns.
