Title:
CERAMIC WIRING BOARD AND METHOD OF MANUFACTURING IT
Document Type and Number:
Japanese Patent JP3652196
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a glass ceramic wiring board which can control the shrinkage in plan direction and enable fine wiring with excellent surface.
SOLUTION: The glass ceramic wiring board on the surface of which the area ratio of voids is adjusted to ≤5% is manufactured in such a way that green sheets composed of a glass ceramic composition containing ≥20 vol.% amorphous component after burning are prepared, and wiring circuit layers composed of high-purity metallic conductors containing ≥99.5 wt.% metallic component are respectively formed on the surfaces of the green sheets. Then the green sheets are laminated upon another and a constraining sheet which is composed mainly of a hardly sinterable ceramic material and containing 0.5-15 vol.% amorphous component is formed on at least one surface of the laminated green sheet body. Finally, the laminated body is sintered and the constraint sheet is removed.
