CONSTRAINING GREEN SHEET AND MANUFACTURING METHOD OF MULTI-LAYER CERAMIC SUBSTRATE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a constraining green sheet and a manufacturing method of a multi-layer ceramic substrate using the same.

SOLUTION: There is provided the constraining green sheet including: a first constraining layer having a surface disposed on one of the top and bottom surfaces of a ceramic laminated body and containing first inorganic powder; and a second constraining layer disposed on the top of the first constraining layer and containing second inorganic powder and a fly ash. Also, there is provided the manufacturing method of the multi-layer ceramic substrate including: a step of providing a non-sintered ceramic laminated body including a plurality of ceramic green sheets; a step of providing at least one constraining green sheet including the first constraining layer containing the first inorganic powder and the second constraining layer containing the second inorganic powder and the combustion material; a step of disposing the constraining green sheet by bonding a surface of the first constraining layer to one of top and bottom parts of the ceramic laminated body; and a step of sintering the ceramic laminated body at a predetermined sintering temperature.
