Ceramic substrate and manufacturing method thereof.

摘要

The method of manufacturing a ceramic substrate having a plurality of bumps of the present invention, includes the steps of: forming a bump forming layer having a plurality of holes therein on at least one of upper and lower faces of a laminated body of green sheets; filling the holes in the bump forming layer with a bump forming paste; sintering the laminated body of the green sheets and the bump forming layer; and forming bumps made of the sintered bump forming paste by removing the bump forming layer.
