ABSTRACT:
A novel metal filled via composition for use with ceramics. The via composition can be formulated to have a volume shrinkage approximating that of the ceramic material, and thus overcomes the problem of volume shrinkage mismatch between the via (particularly copper filled via) and ceramic upon sintering. The novel via composition exhibits enhanced adhesion to the ceramic. A sintering process by which shrinkage of the novel via composition is controlled and adhesion is improved is also disclosed.
