Multilayer ceramic substrate with graded vias |
| abstract |
Disclosed is a multilayer ceramic substrate (30) for electronic applications including:n (a) at least one internal layer (32) having vias (34) filled with a metallic material; (b) at least one sealing layer (40) having vias (42) filled with a composite material that is a mixture of ceramic and metallic materials; and (c) at least one transition layer (46) located between the internal and sealing layers having vias (48) filled with a composite material that is a mixture of ceramic and metallic materials but having less ceramic and more metallic material than the sealing layer vias and less metallic material than the internal layer vias. n Also disclosed is a method of forming the multilayer ceramic substrate. |
